The Best Grammar Checker Software

Best grammar checker tools - 2019

I handpicked these 10 grammar checker tools and tested them for this 2020 review.

Ready to find out which checker software is right for you?

Let’s get started.

1. Grammarly 

Grammarly is a writing assistant that not only corrects your grammar but also gives you comprehensive writing feedback. 

You can use the Grammarly tool to proofread and check for grammatical errors and spelling errors in social media updates, emails, blog posts, articles, and even early drafts of book chapters.

I’ve used the Grammarly free and premium versions since 2015, and I’m most familiar with this tool. 

Key Features

  • Grammarly checks your writing across the web. It works via a Grammarly web extension like the chrome extension, a desktop app for Windows and Mac, and an iOS and Android app called Grammarly Keyboard.
  • The Grammarly extension or browser add-on works as a punctuation checker and grammar checker Grammarly within your WordPress editor too. You can check grammar and punctuation online. You can also run a spell check on your blog post as you write it using the grammarly extension. 
  • The free grammar checker version of Grammarly is ideal if you’re a writer on a tight budget. You can install a plugin for your browser and use grammarly free to check your emails, social media updates, and anything you write online for errors.
  • Grammarly Premium is the paid version that checks spelling and grammar, and punctuation. It is useful if you want to improve your knowledge of English grammar as it provides more writing insights and the reasons behind common grammar mistakes. 

Apart from grammar checks, the grammarly premium version: 

  • Checks for readability
  • Corrects run-on sentences
  • Gives you suggestions to enhance vocabulary and sentence structure
  • Detects plagiarism

How Much Does Grammarly Premium Cost?

What’s better?

Grammarly offers human proofreader services.

You can also send extracts of your work straight to a human proofreader within Grammarly for between 0.02 and 0.12 of a cent a word depending on how quickly you want the document returned.

Grammarly Review

The Grammarly editor identified the grammar, punctuation, and spelling errors in my text in a sidebar.

I fixed them one by one by scrolling down. It also caught and fixed the punctuation errors and grammar issues that Microsoft Word ignored – like text written in the passive voice. You can, of course, write in this voice, but it’s less engaging to read.

Grammarly offers context to each mistake, helping you improve your writing skills. The premium version of Grammarly editor also indicates errors in sentence structure.

Like other punctuation checker tools, it also recommended adding some commas in the text that Whitesmoke and Ginger ignored.

Apart from checking grammar and punctuation, the tool also has a plagiarism checker, which allows you to check your article against billions of web pages for unoriginal text.

If you don’t want to pay to check the originality of your content, try Dupli Checker – it is an efficient and free plagiarism checker tool.

However, Dupli Checker and all free plagiarism checkers place a limit on the number of words you can check. Grammarly is a lot quicker, besides being more accurate as a plagiarism checker!

I’ve reviewed the Grammarly tool at length. If you’re interested, read my full Grammarly review.

Note: I used the desktop version of grammar checker grammarly and not the grammarly keyboard.

Grammarly writing insights

Pros

  • Easy to use with an excellent user interface
  • Features a powerful online spelling and grammar checker
  • Great writing insights

Cons

  • Grammarly Premium version is expensive for new writers
  • No personal dictionary like Ginger

Ease-of-use: 4.5/5

Accuracy: 5/5

Affordability: 4.5/5

Total: 5/5

Try Grammarly

2. Ginger

An Israeli startup created Ginger in 2007, making it one of the more established spelling and grammar checkers on the market.

Like Grammarly, Ginger offers free grammar and spell check as well as premium online proofreading software.

Key features

  • The quickest way to get started is by installing a Chrome extension or any other browser extension. 
  • It is also available for advanced tools like Slack. It provides apps for Windows and iOS. 
  • You can use a keyboard for Android. Or, you can paste extracts of your text into their web app. You can also use it as a punctuation checker to correct your text in Gmail.
  • Ginger reveals the character count, word count, and the number of sentences for your text. 
  • The tool also helps you find and fix synonyms for commonly overused words like make.
  • Ginger identifies grammatical errors and spelling errors by highlighting them in blue.
  • Like Grammarly, Ginger Premium offers more context for grammatical mistakes and identifies more issues than the free grammar checker version. For instance, it has advanced features to check for grammar rules like subject-verb agreement.
  • Interestingly, Ginger can translate extracts of your writing into 60 other languages, including Spanish, German, and even Yiddish. Sure, Google Translate also does this, but being able to check a document for grammar issues and translate from within one app is useful.
  • A Ginger Premium subscription also includes a virtual writing tutor who provides video grammar lessons and tests for improving your English grammar. This English grammar checker feature should appeal to those learning or writing in the language for the first time.
  • This makes Ginger online grammar corrector ideal for non-English native writers—you could write in Yiddish, translate to English, and then grammar check your writing all within Ginger.
  • You can also add words that you don’t want to identify as mistakes to a personal dictionary within the Ginger grammar checking tool. I could see this appealing to fiction writers with unusual character names for their stories. (I wish Grammarly would add this feature!)

How Much Does Ginger Software Cost?

Ginger pricing at time of writing this best grammar checker review

At the time of writing this best grammar checker review, Ginger was offering a discount of 30% on its premium plans. You can also avail of a 7-day, 100% money-back guarantee.

Ginger Review

For this Ginger review, I used the Chrome extension of this grammar checker software. Unlike Grammarly, Ginger doesn’t offer a Mac desktop app yet.

When I pasted my 600-word article into the Ginger web app, it copied the formatting of my document, putting headings in bold and so on. Grammarly and Whitesmoke don’t do this.

So kudos to Ginger for that!

Like Grammarly, Ginger identified all of my grammar errors, spelling errors, and punctuation mistakes as well as the ones MS Word missed. 

However, Ginger was less insistent about fixing my inconsistent comma usage in the text.

Interestingly, Ginger Premium missed a spelling mistake in one of my headings. While you may wonder if it’s spell checker function is top-notch, this particular mistake can be attributed to a formatting issue, which I explain in my video review. 

I also had to hover over all grammar errors and punctuation errors with my mouse rather than reviewing them in a sidebar. This meant I spent more time correcting my grammar errors. It’s a small gripe, but I’m a little obsessed with workflows!

Pros

  • The free version of Ginger grammar checker software is relatively powerful
  • Useful for non-English native speakers thanks to a virtual writing tutor and translation features
  • Personal dictionary a nice addition

Cons

  • Hovering over grammatical mistakes slows self-editing somewhat
  • Some accuracy issues depending on how a document is formatted

Ease-of-use: 4.5/5

Accuracy: 4.5/5

Affordability: 4.5/5

Total: 4.5/5

3. Whitesmoke

The software company, Whitesmoke, was set up in 2002 to sell affordable online proofreading software for Mac and Windows.

Key features

  • You can use Whitesmoke to check your articles for spelling and grammar mistakes, punctuation mistakes, and more. It’s useful for writers and non-English speakers on a tight budget 
  • It identifies errors in sentence structure
  • Whitesmoke works in almost all browsers, including Chrome, Safari, Opera, and Firefox, depending on what version you subscribe to
  • You can also download apps for iOS and Android 
  • Whitesmoke Essential is a version that’s compatible only with your web browser
  • Whitesmoke Premium (what I tested) offers additional support and apps for Mac, Windows, Gmail, and MS Office
  • The version of Whitesmoke I tested for this best grammar checker review features a translator, although it supports eight languages rather than 64 (no Yiddish!)
  • Whitesmoke grammar corrector also offers several templates for writing projects like cover letters, grant proposals, thank you messages, and so on

Whitesmoke is one of the cheapest online proofreading software that I’ve featured in this review. Like grammarly editor, the company updated its user interface in 2018.

Whitesmoke grammar checker in action
 

How Much Does Whitesmoke Cost?

Unusually, Whitesmoke doesn’t offer monthly subscriptions.

You can save more money if you buy a three-year subscription, at the time of writing this best grammar checker review.

Whitesmoke Review

Whitesmoke is more affordable than Grammarly. It’s accurate, too (as you can see in my video comparison review).

However, Whitesmoke isn’t as fast or as easy to use as Grammarly.

Making changes to your documents also involves an extra step compared to Grammarly in that you must export the final version to a text document.

Like ProwritingAid, it’s cheaper than Grammarly. And, unlike ProWritingAid, you get to download mobile apps as well.

Pros

  • Affordable, provided you don’t mind paying yearly
  • Accurate
  • Relatively easy to use
  • Suitable for businesses

Cons

  • User interface lags behind Grammarly and Ginger
  • Slightly slower than Ginger and Grammarly

Ease-of-use: 3.75/5

Accuracy: 4.5/5

Affordability: 4.5/5

Total Score: 4/5

Try Whitesmoke

4. ProWritingAid

ProWritingAid is a London-based software firm founded in 2012. This software tool acts as your virtual writing tutor and grammar checker as well as a personal writing coach. 

Since writing this grammar checker review and recording the above video, I received several questions from readers and commenters about ProWritingAid. So I tested this spelling and grammar checker thoroughly.

Key features

  • ProWritingAid integrates with MS Word/Outlook, Google Docs, Open Office, Final Draft, and even Scrivener.
  • You can download a desktop app for Mac and Windows or install a plugin for your browser. ProWritingAid also offers Word and Google Docs plugins.
  • You can use the browser extension for Chrome, Firefox, Edge, and Safari, to check your writing on any website, including Medium, Facebook, Twitter, Gmail, and Wattpad.
  • You can paste text and check for grammar and spelling errors in a web editor. Alternatively, you can upload a document containing your writing.

How Much Does ProWritingAid Cost?

Prowriting Aid offers a two-week free trial. After that, prices are as follows:

This makes ProWritingAid the cheapest grammar checker in this review.

ProWriting Aid Review

Prowriting Aid report - review 2018

When I pasted my text into the ProWritingAid web app, it kept the source formatting, including my choice of colors and fonts.

The grammar checker underlined grammar mistakes, spelling issues, and other suggestions.

At first, I found the various types of reports overwhelming. But, they quickly made sense once I clicked through each suggestion or mistake.

I particularly liked a feature called Echoes. This feature identified places where I overused turns of phrase and other words.

This is a useful feature for improving your writing skills. It also identified some clichés in my writing.

This struck me as particularly useful for fiction writers who want to improve the quality of their sentences and sentence structure.

The prowritingaid premium version I tested only supports British and American English, so it’s less ideal if you write in more than one language or you’re learning English.

ProWritingAid also took longer than Grammarly and Ginger to identify these mistakes, and the user interface wasn’t as polished.

Anyone who wants to write for the web like a blog post should try to write for an eighth or ninth grade audience (a Flesch reading score of above 70%).

The good news is, apart from specifying grammar rules, ProWritingAid will also help you figure out the readability of your articles based on the Flesch Reading Score. This is great for improving your web writing skills.

Why are readability and Flesch scores important?

Well, web readers have a shorter attention span than those consuming print (look a squirrel!). It is really easy to simplify and tailor your blog post for this audience with ProWritingAid.

Although the WordPress plugin Yoast also gives you this feature, it’s useful if you write outside of WordPress.

ProWritingAid Works With Scrivener

The desktop version enables you to open Scrivener files directly in ProWritingAid, fix typos and other grammar issues, and then save back to Scrivener.

This is a clever feature. But, I prefer to run the final exported books file from Scrivener through a grammar checker before moving to Vellum for self-publishing.

I also only use Scrivener these days for long-form writing and instead rely on iA Writer for producing articles like these.

In short: your mileage may vary depending on your writing workflow.

If you’re on a tight budget and can’t afford the other premium grammar checkers in this review, ProWritingAid premium makes a good choice. It’s also useful for fiction writers and those who use Scrivener a lot.

Pros

  • The most affordable spelling and grammar checker I have reviewed
  • Relatively accurate
  • Lots of nice features for self-editing
  • Suitable for fiction writers and Scrivener fans

Cons

  • Slower than Grammarly and Ginger
  • User interface lags behind other grammar checkers
  • Less useful for with English as a second language
  • No mobile version

Ease-of-use: 3.5/5

Accuracy: 4.5/5

Affordability: 5/5

5. After the Deadline

After The Deadline is a web app to find your writing errors and get smart suggestions. 

I’ve used After the Deadline on and off for years as a english grammar checker for checking blog posts.

After the Deadline -grammar checker review

Key Features

  • You can install this as a free grammar checker browser plugin for Chrome and Firefox.
  • It highlights misused words in red, grammar mistakes in green, and style suggestions in blue. 
  • It’s also free for personal use.

How Much Does After The Deadline Cost?

This is a free grammar check software.

After The Deadline Review

It is easy to use and is ideal for bloggers and anyone who publishes articles on their website.

It catches more errors than MS Word. 

This grammar checker will also help you identify clichés, redundant words, and so on.

If you’re a blogger, I recommend using After the Deadline to check your posts before you hit publish via the WordPress plugin.

However, I had trouble getting the Chrome plugin to work properly while writing this review and preferred the Grammarly plugin for checking my writing outside of WordPress.

Pros

  • Works great with WordPress
  • Fast and easy to use
  • Free grammar checking tool

Cons

  • Less useful outside of WordPress
  • Barebones

Ease-of-use: 3.5/5

Accuracy: 4.5/5

Affordability: 5/5

Total: 4/5

6. Microsoft Word and Google Docs

Both Microsoft Word and Google Docs have grammar checking features built into them.

If you’re a writer on a budget, don’t worry about the premium grammar checker tools in this review for now. Both of these punctuation checker tools will work just fine. 

Key Features

  • To use Word, you can install it on a select number of Windows and OS X computers once you buy the Microsoft 365 suite.
  • To use Google Docs, you can simply log in to your Google account from a browser and go to docs.google.com. You can use it on any computer and browser, including Windows, Mac OS X, Linux, and Chrome OS.
  • You could use both tools to catch typos and other mistakes before hitting publish or sending your writing to someone else. As you type, you’ll find a red line under errors which you can click or right-click and correct quickly.
  • Word offers suggestions for synonyms and readability and synonyms.
  • Google Docs offers spelling suggestions, as well.

How Much Does Microsoft Word and Google Docs Cost?

Word comes as part of the Microsoft 365 package (Office 365) that starts from $6.99 a month. This includes MS Excel, PowerPoint, Outlook, Publisher, and Access.

Docs is free for use. You can also buy a G Suite “business” version at monthly plans that start at $5 per user.

Microsoft Word and Google Docs Review

You can check shorter articles using these tools.

I recommend printing out longer articles and reading them aloud as another line of defense. You should also always hire a proofreader if you’re an author.

That said…

These in-built grammar checkers won’t help you find and fix clichés, redundant writing, and so on.

Pros

  • Google Docs is free, and MS Word comes with the popular MS Office suite, which you’d be using for other purposes anyway.
  • Grammar check and spell check are inbuilt in the tools, so you needn’t copy and paste it any other tool.
  • You can get your text translated into a 100 languages for free on Google Docs.

Cons

  • Both tools don’t have advanced grammar or style checks as like the other dedicated tools
  • Slower than using a dedicated grammar checker

Ease-of-use: 4/5

Accuracy: 4/5

Affordability: 4.5/5

Total: 3.5/5

7. SpellCheckPlus

SpellCheckPlus is a useful and affordable grammar checker if English isn’t your first language.

Like Ginger, SpellCheckPlus will help you learn more about writing in a second language and the intricacies of English grammar.

SpellCheckPlus -grammar checker review

Key Features

  • It is a virtual writing tutor and grammar checker which allows you to paste extracts of your work – up to 2,000 characters at a time.
  • It scans your extracts for complicated language, redundant words, and so on.

How Much Does SpellCheckPlus Cost?

SpellCheckPlus is a free grammar checker.

SpellCheckPlus Review

I liked how SpellCheckPlus summaries errors and also provides context.

Unlike the other grammar checker tools in this post, it’s a barebones grammar checker for finding and fixing errors on the go.

You can’t add custom words to a dictionary, specify writing styles, and so on. So, it’s less useful for fiction writers. You also can’t use it outside of a web browser.

I prefer using dedicated apps to checking longer pieces of writing as I get distracted easily.

Anyhow, this grammar checker is free and effective if you want to check shorter pieces of writing.

If you want to check extracts longer than 2,000 characters, it costs $14.99 for a year. That’s an affordable price for most new writers.

Pros

  • Free for use
  • Easy to use

Cons

  • Works via a web-browser only
  • Feature-light

Ease-of-use: 3.5/5

Accuracy: 4.5/5

Affordability: 5/5

Total: 4/5

8. Hemingway Editor

The American author Ernest Hemingway famously said:

“All you have to do is write one true sentence. Write the truest sentence that you know.”

Hemingway Editor -grammar checker review

Hemingway Editor is built to help you write that true sentence and discard everything else.

Today, I rely on this tool and Grammarly the most for editing my work.

I use grammarly web to check my articles and book chapters for mistakes. I also paste second and third drafts into Hemingway Editor while self-editing.

Key Features

  • Hemingway Editor highlights complex sentences in red, instances of the passive voice in green and adverbs in blue. Deciding which sentence structure to fix or ignore is down to your taste and writing style.
  • You can mouse over them for hints.

How Much Does Hemingway Editor Cost?

You can use the web app for free or download a desktop app for Windows or Mac for USD19.99.

Hemingway Editor Review

I use the highlights feature to identify what to find and fix while self-editing.

Hemingway Editor doesn’t offer suggestions or provide context like the other grammar checker tools in this post. It does, however, help me write more clearly.

This virtual writing tutor is fast and efficient too.

The desktop app doesn’t have any additional features. That said, I like using it as I get distracted when writing within a web-browser.

Pros

  • Ideal for self-editing
  • Ideal for fiction and non-fiction writing
  • Complements Grammarly (or whatever tool you prefer)

Cons

  • Not a replacement for a dedicated grammar checker
  • Less features than other grammar checkers in this post

Ease-of-use: 5/5

Accuracy: 4/5

Affordability: 4/5

Total: 4.5/5

9. GrammarChecker

GrammarChecker is an online spell check tool that analyses your writing for grammar, punctuation, spelling, and stylistic errors.

Grammarchecker.net -grammar checker review

Key Features

  • It rewrites shorter pieces of writing automatically.
  • It finds suitable synonyms, swaps out words, and so on. The result is supposed to be SEO-friendly, plagiarism-free text.
  • It supports many different languages, including French, Spanish, German, and Arabic.

How Much Does GrammarChecker Cost?

This tool is free for use.

GrammarChecker Review

I was uncomfortable with this tool as I like to review and reject edits manually.

I also found the accuracy off-putting. It didn’t catch some grammar mistakes and errors in my work and inserted some odd words.

To be honest, I’m not sure what type of writer would consider a paraphrasing tool like this useful.

Pros

  • Simple interface.

Cons

  • Can be used only via a web browser.

Ease-of-use: 2/5

Accuracy: 1/5

Affordability: Free

Total: 1/5

10. Reverso

Reverso is an online translator and spelling and grammar checking tool developed by Reverso-Softissimo.

Reverso -grammar checker review

Key Features

  • This tool can translate your text into different languages, including German, Italian, Arabic, Hebrew, Spanish, and more.
  • Reverso works via a web browser, a Google Chrome plugin, and a Google Play and iPhone app. It works offline, and you can speak words into the app if typing isn’t for you.
  • Reverso provides corrections and suggestions and more information via an in-built dictionary.

How Much Does Reverso Cost?

Reverso is free for use.

Reverso Review

As it has a word-count limit of 600 characters, this online writing tutor is useful for checking or translating shorter pieces of writing. Examples include a brief email or a social media post.

I liked how I could check the definition of certain words and their synonyms via one or two clicks within Reverso. This is a useful method for self-editing. 

Reverso also provides context that will help you learn English.

After some digging, I found out the tool is powered by Ginger software, which explains its support for non-English languages. It’s a useful tool, that works much like Ginger.

Pros

  • Works much like Ginger
  • Easy to use mobile app
  • Useful for non-English writers

Cons

  • Less features than other grammar checkers in this post
  • Grammarly is a little faster

Ease-of-use: 3/5

Accuracy: 4/5

Affordability: Free

Total: 4/5

Now:

Are you looking for Free Grammar Checker Tools Only?

Most of these tools have free versions. Although they’ll have limited features, they will correct the most common grammar mistakes.

However, I do recommend that you go for a premium tool to ensure that you detect advanced instances of the passive voice, subject-verb agreement, and other tricky errors. 

A free version might skip these. And, they’re hard to spot manually.

Research Process: How I Tested Tools for This Best Grammar Checker Review

I started by using the four most popular grammar checker tools today: Grammarly, Ginger, Whitesmoke, and ProWritingAid.

I ran a small experiment to test different tools in this best grammar checker review.

  • I wrote a 600-word non-fiction article on the go in MS Word. It contained many grammatical errors and spelling errors.
  • The MS Word online grammar checker found most of my errors, but it missed a few grammar mistakes, including a missing word in a sentence.
  • I bought the premium versions of these tools, and pasted the article into the relevant app for Mac or Chrome. 
  • Then, I compared how each grammar checking tool treated the text.
  • Later on, I experimented with the other tools referenced towards the end of this review e.g. Reverso, SpellCheckPlus, and so on.

That said, you can always go back to the old-school way of proofreading or hiring a writing tutor at any time – for a change. 

Here are some ideas:

Proofreading Tips

As you know, proofreading is a different skill set from writing.

It’s difficult to spend hours working on a draft and then find and catch errors by yourself. Much like the hiker who spends hours inside a forest, you won’t be able to see the woods from the trees.

These days, I use grammar checkers like the ones in this review to find errors fast. I also work with an editor who checks my articles and book chapters for errors.

You can also proofread your writing using an old journalist trick!

Here’s how:

  1. Change the font to Courier or Courier New.
  2. Change the spacing to double.
  3. Print your writing out.
  4. Get a red pen and mark it up.
  5. Read aloud, listening for clunky language.
  6. Edit as needed.

Thanks to this mono-spaced font and the extra white space, your eagle-eye will spot issues like run-on sentences easier, and your ear will catch them.

If it’s a shorter piece of writing, you can read aloud from the screen.

Ideally, you should:

  • Let your manuscript rest for a few hours or even days before you proofread it so you can approach it with fresh eyes.
  • Proofread in a quiet place with minimal noise, away from your computer.
  • Mark up your manuscript with a pen rather than fixing it as you read.
  • Read your manuscript backward (this pattern interrupt will help you find more errors).
  • Read your manuscript several times, each time looking for a different type of error e.g., punctuation, numeracy, clumsy sentences, etc.
  • Ask a colleague to proofread more important documents.
  • Accept when you make a mistake: nobody is perfect, even newspapers print retractions and corrections.

Now, here’s a comparison between Grammarly and the other top grammar checkers.

Grammarly vs. Some of the Top Grammar Checking Tools

Most grammar checking tools have features comparable to Grammarly. But, there are some crucial differences as well. 

Let’s see what they are.

Ginger vs. Grammarly

Ginger and Grammarly are relatively similar online grammar and spell checker tools.

There’s little difference in the pricing, and both the online grammar checkers are accurate. They also find your spelling errors easily. The features of both products are consistent too, apart from the Grammarly Mac desktop app and MS Word plugin.

However, Ginger is useful if you write in more languages than just English.

It’s also a good grammar checker tool if you want to learn more about English grammar by taking the various lessons inside of Ginger.

These days, I use Grammarly more than Ginger as I prefer the Grammarly user interface and Mac desktop app.

Whitesmoke vs. Grammarly

Whitesmoke is cheaper than includes support for more languages than Grammarly. I also didn’t notice any considerable differences in accuracy between the two tools while writing this review.

However, while Whitesmoke will check your grammatical mistakes and improve your sentence structure, it isn’t as fast or intuitive as Grammarly. The Whitesmoke mobile and desktop apps don’t look as good as Grammarly’s either.

So, in short, you can trade speed and looks to save a little money on your grammar checker of choice.

ProWritingAid vs. Grammarly

I’ve used Grammarly for years because it’s fast and accurate. That said, some new writers don’t like paying the monthly subscription fee, which I understand.

If you want to use a more affordable tool than Grammarly, consider ProWritingAid.

It’s not as fast or as easy to use as Grammarly. They also don’t have mobile grammar checker apps.

However, ProWritingAid is relatively accurate and more affordable. It’s also particularly useful if you like Scrivener or write fiction.

After the Deadline vs. Grammarly

After The Deadline had a popular WordPress plugin, which has now been discontinued. This software is good for writers who want a free, basic alternative for spelling and grammar checks. It doesn’t have the advanced features and suggestions offered by Grammarly.

Word and Google Docs vs. Grammarly

The advantage of Word is that you can work offline using the desktop version. You can also use the Google Translation features in Docs.

But, they both don’t offer the full feature set that a tool like Grammarly does. It’s a full-featured spelling, style, grammar and punctuation checker. Grammarly gives you the suggestions to correct your mistakes, and reasons for those suggestions. Also, you can use it on the web or mobile, and in word processing software like Word.

SpellCheckPlus vs. Grammarly

Grammarly is higher in accuracy and can also check for plagiarism, which SpellCheckPlus cannot. 

Hemingway Editor vs. Grammarly

Hemingway Editor points out the overuse of adverbs, something that Grammarly doesn’t do. 

However, it doesn’t provide suggestions on fixing issues and isn’t customizable to writing styles (formal, business, and so on) like Grammarly.

Grammar Checker vs. Grammarly

Although Grammar Checker catches the contextual mistakes of English sentences, it is less accurate than Grammarly. For instance, it doesn’t point out missing punctuation or English grammar errors.

Reverso vs. Grammarly

Reverso offers useful contextual translations, but it’s a great free option only for basic grammar checks and translating. 

Which are the Best Grammar Checkers in 2020?

Please remember, always work with a human proofreader for longer pieces of writing – like a book chapter or a lengthy article.

Having worked on a translation project for a large company, I’d also caution against solely relying on software to translate your writing from your language of choice to English.

A virtual writing tutor, much like any book editing tool, is useful. 

But, I don’t consider it as a replacement for common sense or a set of human eyes. Instead, these products are just one of many that belong in your toolbox.

That said…

All of these grammar checkers will help you get the job done and fix issues in your writing. 

And, my top pick is: Grammarly.

I use Grammarly the most out of these proofreading tools. I prefer its applications and user interface—but that’s down to my tastes only. I also don’t need to learn English.

Well, many new writers email me to say they can’t afford to pay for Grammarly Premium. It’s hard to fault useful proofreading software that costs less than $7 a month.

In short, test the free versions of any of these 10 tools and then decide which fits best with the way you work—or write.

Have you got questions about this best grammar checker review? Check the FAQ section below for answers to some of the common questions.

FAQs

Who needs a spelling or grammar checker?

Everyone can use a spelling or grammar checker. At the bare minimum, they will teach new writers more about English and grammar.

Any writer who takes their craft seriously should use a premium grammar checker as another line of defense. They will help you find and fix errors faster. 

As good as they are, please remember to hire a proofreader if you’re an author.

Is there any good English grammar checker that doesn’t require a monthly fee?

Consider the free versions of Grammarly or Ginger. You don’t need to pay a monthly fee to use them. Alternatively, try SpellCheckPlus or WhiteSmoke.

Why aren’t there any grammar checkers that work offline?

Grammar checkers rely on software that works online or in the cloud. If you want an offline grammar checker, use Microsoft Word or Hemingway Editor.

Alternatively, write your earlier drafts offline. When you’re finished, go back online and paste your draft into a grammar checker of choice.

WhiteSmoke is also useful if you are writing articles, essays or early book drafts offline.

Is a grammar checker safe to use?

Unless you’re writing something legally or commercially sensitive, then yes. A good grammar checker won’t monitor your content. As an example, check out Grammarly’s Privacy Policy.

If your document is legally sensitive, a grammar checker is unlikely to help you.

I’m worried about plagiarism, what should I do?

A grammar checker like Grammarly can help you find instances of plagiarism online. Simply paste your work into it to find out if there’s any plagiarism.

A good grammar checker or writing tutor will also scan your draft and tell you if it’s too much like another well-known piece of writing. That’s useful for college students who are new to research and writing essays.

If you’re worried about being plagiarised, it’s highly unlikely that anything you paste into a grammar checker will be used elsewhere.

Which are some good grammar and punctuation checker apps?

Grammarly, Ginger or Hemingway Editor are all good.

What’s the best grammar checker for writers?

I use Grammarly and Hemingway Editor regularly. I write non-fiction, and these serve my needs as they are affordable, accurate, and fast.

Ginger is also useful for non-fiction and non-English writers.

Fiction writers should also consider ProWritingAid.

Is Microsoft Word grammar checker accurate?

Yes! This writing tutor does the job if you’re on a budget. That said, I always recommend printing out longer pieces of writing (more than 1,000 words) and hiring a proofreader for books.

What’s the best free grammar checker on the internet?

Consider SpellCheckPlus as a writing tutor for checking writing on the go. If you’re a blogger or use WordPress, install the Jetpack plugin and turn on After the Deadline.

Is Grammarly a reliable grammar checker?

It’s my tool of choice. Check out my Grammarly review and claim a discount.

I’m looking for online grammar checker tools that are not Grammarly. What should I pick?

Ginger is the most comparable. Alternatively, consider WhiteSmoke.

What are some other websites like Grammarly?

Ginger is the most similar to Grammarly, followed by Reverso. It offers more support for non-English writers. 

What are the grammar checker apps on a mobile?

Grammarly Ginger and Reverse all work on mobile. Ginger and Reverso will help if you write in other languages. You can also use the dictionary built into your smartphone, although it’s less accurate.

What are the best online English grammar checkers for blogging?

If you’re pasting final drafts into WordPress, I would recommend you install the Grammarly or Ginger plugins.

What grammar checkers work with Word?

WhiteSmoke works quite well with Word. It provides options not available in Word, such as templates and a detailed thesaurus.

71 thoughts on “10 Best Grammar Checker (2020 Update): Grammarly, Ginger, ProWritingAid, And More”

  1. Never even heard of Ginger or Whitesmoke. How in the world wasn’t ProWritingAid included in this? I’ve used it and Grammarly, and ProWritingAid beats it hands down. And from what I see of the other two from your review, it’d probably top those as well.

    Pricing’s better as well. The cost of a yearly membership for Grammarly is the equivilant of the one-time lifetime subscription from ProWritingAid. And if you sign up for ProWritingAid’s free newsletter, eventually they send you a half-off coupon for the lifetime subscription (I’ve known this to happen for at least half a dozen other writers).

    Grammarly isn’t bad, though I found it to be a bit glitchy if using the desktop app. Best of all, it will natively open all the major file formats (including Scrivener projects) so there’s none of this “copy-and-paste-oh-wait-which-version-is-the-new-one-and-hey-did-I-copy-my-changes-back-over-the-original?” stuff.

  2. How do we get a discount on Ginger? This is a great article, as someone who is just stating to delve into Grammar checkers for short articles I found this very insightful and helped me narrow things down!

  3. I appreciate the review. I used Grammarly for over a year. When I first signed up, I got a nice discount, but that was only available to new customers. when my auto-renewal came up, they would not negotiate on the price.

    I had become accustomed to the Grammarly sidebar, so it was hard to adjust to ProWriting Aid, but I am stils searching. I appreciate your review.c

  4. Ginger is fairly close to Grammarly. I actually prefer the highlighting of possible corrections in Ginger to the Grammarly sidebar because I often wasted time locating the small changes noted in the Grammarly sidebar. Ginger highlights in blue so it’s harder to miss. Also easy to add to the personal dictionary of Ginger.

    1. I don’t think so, however you could always copy your writing into your grammar checker of choice when you’ve finished editing in Libre Office.

    First, hello Bryan and thanks for the useful comparisons. I just happened on the site while checking out why I keep hearing about Grammrly. Now I see C.L. (hi CL) has said exactly what I was going to say. I have ProWritingAid and love it. Like another comment below if I had tried Grammarly first I might not be as content. But now that I’ve seen the pricing structure of other tools my view that ProWritingAid is great value (once off reasonable payment) is reinforced.
    By the way I use it mainly for short stories, and like you said it also teaches a lot about good writing practice. (I’m sure the others also do that). I know you reviewed it since CL commented, but I’m just throwing in my tuppence worth because articles and comment sections like this have been a great help to me.

  6. I am wondering if you used any of these tools on this post. If so, did none of them notice that the second and fifth sentences are nearly identical?

    Otherwise, thank you for the useful comparison.

  7. Hi! My name is Joe and I’m a freelance writer who has a passion for writing and I believe I can add value to your audience. I know that you accept guest posts on your site/blog, so I’d really like to write on these topics:

    – 10 Incredible Content Writing Tools For Amazing Marketing;
    – 9 Content Strategies You Need For Your Business;
    – 11 Top-Notch Proofreading Tools for Content Writers.

    I’m sure it can be a good fit for your website.

    Thanks and looking forward to hearing from you 🙂

    Best regards,

    Joseph McLean.

  8. Hi Bryan,

    thanks for taking the trouble to do this comparison, but I’m afraid I have many problems with this blog post.

    First of all, it’s not a great advert for any of the products since so many glaring mistakes made it through.
    * “english” without a capital E (multiple times)
    * missing words (several times)
    * wrong words
    * missing punctuation
    * odd phrasing

    I also watched your video. I’m afraid that there’s a mistake in Grammarly’s correction of the sentence “Today Ohno known as…” Grammarly’s correction is “Today Ohno was known as…” but it should be “is known as”.

    Which leads me to another problem with the post. You write “…grammar issues that Microsoft Word ignored like text written in passive voice.” Passive voice is not a grammar issue for any variant of English apart from American English. In fact, it’s not an issue in most languages apart from American English. It has a variety of legitimate uses, all of which Grammarly ignores. While it may be true that American publications frown upon its use, it is perfectly legitimate in British (and I imagine Irish) publications. Can you imagine a scientist writing up an experiment NOT using passive structures?! (I’ll gloss over the lack of punctuation)

    Am I correct in thinking that none of the products caught the lack of punctuation in the sentence after “Today Ohno…” ? There are three sets of inverted commas rather than four.

    To be honest, I’m a little worried when you mention in the video that it can simplify your writing. Why does everything have to be simplified these days? Can people no longer think for themselves?

    Finally, I feel you could have mentioned that Word for Windows has a plugin, so there’s no need to upload a text, and thus you can preserve any formatting.

    It was an interesting blog post and certainly gave me food for thought.

    Thanks again,

    Mark

    1. Thanks for the feedback Mark. I am planning on updating this post later in 2019 and will factor in your feedback. I always recommend using a human proofreader for longer pieces of work. These tools are useful but they don’t catch everything.

  9. Interesting review.
    I haven’t shopped for a spellchecker for years but have been hearing a lot of Grammarly commercials lately so I thought I would do some research.
    Could you add TinySpell to your comparison for those of us who haven’t looked at this field for a while and still use that?

    Thanks

  10. Hi, I use Grammarly and ProwritingAid. I found ProwritingAid to be a more thorough editor because of all the filters you can run it through. Both extensions when I added them to Chrome seriously screwed up my computer, so I took them off. It was not worth it!!! However, I appreciate the article, it’s very helpful.

    1. 100% agree. WhiteSmoke is junk and waste of money. This is because I found it with serious errors. Don’t recommend WhiteSmoke at all.

  11. I use word on my Mac and I want to make sure ProWritingAid Premium can work with that. I write full length novels and I want something that can work without pasting it to other programs. Also, I don’t use scrivener but may start using Vellum.

    I need a good editing tool that does more than spelling and grammar. I need more along the lines of an editor and that program that seems to give me that is ProWritingAid Premium.

    Do you concur? and thank you for the reviews.

    keith

  12. I use both Grammarly and Whitesmoke. I prefer grammarly becaus user friendly and easily to use. PROS: Synonym function that help to choose the proper word. However, it is not user friendly. Desktop version did not function properly such as translator, it also cannot be reinstall with the window version updated after some function of Whitesmoke cannot work properly. The web log in is error so often, it keeps showing username and password wrong, while the support team take too long to reply the issue, and not follow or provide the possible solution. CONS: The billing department for cancellation did not response the related issue about the refund. The customer service did not offer any helps and solutions. And finally they lose your contact without any responses or responsibility. I decide to get the refund, but I have not any response from the billing department, just only automated responses sent back. Hope this helps before subscription.

  13. “You can, of course, writing in the passive voice but it’s less engaging to read.” You meant “write”/”be writing”?

  14. What about Grammarlookup.com? I think it’s better than 5 of the listed in your post, It’s a free online Spell and grammar checker, uses AI to improve style and structure of your sentence.

  15. Hi Bryan,

    Thanks for writing this helpful article.

    Have you tried out Sapling? (Sapling.ai)

    We’ve developed it to learn from data so it catches many more mistakes than any other tool out there. Here’s a funny example we encountered recently:

    “We plan to cut homeless people in half by 2025.”
    Sapling suggests: “We plan to cut *the number of* homeless people *by* half by 2025.”

    It supports most websites and there’s a Google Docs plugin as well.

  16. Hi,
    I have used the premium versions of Grammarly, ProWritingAid and White Smoke.
    As an all-round resource for creative writing, I found ProWritingAid to be very good, but its detection of common grammatical errors is inferior to both White Smoke and Grammarly. Grammarly is the most accurate, but it is expensive. If ProWritingAid could improve their accuracy in detecting common errors, then I would stay with that product.

  17. Thanks for sharing the valuable information. Writing correct spellings is one of the most important things whether you are a student or a professional, if you write wrong spellings with the wrong grammar, it will make you feel ashamed and put your self-esteem down in front of others. So, you should take help of grammar checker tool. I always prefer NOUNPLUS to check my English writing.

  18. Eileen Faulkner

    I recently purchased ProWritingAid premium at half price after having tried it for a one year fee previously. So much more has been added since my first trial and i am looking forward to familiarising myself with all new additions.
    I have tried the free version of Grammarly and found it helpful. however, I cannot afford to buy too many of these checkers, being a senior citizen and lacking the necessary to do so, so will stick with my PWA and their very helpful monthly blog posts explaining so much.
    May i wish everyone here the best of luck with all future projects, too?

  19. Thank you, Mark! I came on your website after looking for alternatives to Grammarly.
    I’m looking for a grammar and spell checker to review all my posts over at https://itexperience.net . I’ve never used a checker before. Since I’m not native English, I’m sure there are a lot of errors to be corrected

  20. Thanks for the valuable information and in-depth review I would ask that for a future (or amended) head-to-head, to include LanguageTool. It’s open-source, with a paid option. I have no affiliation with any grammar applications/extensions. I generally search alternativeto.net for open source alternatives to freemium, abandoned, discontinued software.

  21. Bryan,

    I sent you a note via your Contact page but wanted to also add another tool to this list that just may surpass what’s listed in comparison.

    Please see Antidote https://www.antidote.info/en/antidote-10.

    With over 1.2 M users worldwide…. used by professional writers, business writers, students and more – it’s worth the review.

    Very best and thanks for the informative piece.

    1. I was going to suggest Antidote as well. I started using it many years ago when it only supported French. It has supported English for many years now and I have yet to find something better.

  22. Гульнара Самигулина

    Hi! It is a great app! Thank you! But I have a problem to login into my account. I recovered my password, but they write that there is no matching between password and e-mail. How can I solve this problem?

  23. In any case, I recommend you not to install Ginger! It requires to make an account with no option to delete it. I tried to uninstall and delete it, but unsuccessfully again. It’s continuously spamming me and now I have to reinstall my Windows…

  24. Nicely written, Bryan.
    I still love Ginger. As far as I remember Ginger was the first ‘Popular’ Grammer checker and Grammarly followed the footsteps of Ginger. Finally Grammarly won 😀

    Now I’m using Grammarly on a daily basis.
    Since I’m not a native speaker, Grammarly is helping me a lot when communicating with my clients and coworkers. Yup, I’m a freelance social media marketer and I’m sending at least 15 emails a day. So yeah, it is quite a bit of writing and Grammarly is saving my day.

  25. Amelia Williams

    You have shared a very informative post which is really very helpful. Writing with perfect grammar is hard to do unless if you’re a grammar expert. Many peoples have problems with grammar and spelling. I always prefer NOUNPLUS.

  26. Hi Bryan
    I have dyslexia and need to write grants mostly on the internet. I have problems with transposing words such as my/by, but/put, man or/manner punctuation, and run on sentences. I’m tired of having to have someone go over my work. I own a non-profit organization which has a website that I need to write up, would like to have a newsletter, use Facebook, other social media. Can you suggest one of your reviewed grammar programs that would work best for me?

  27. As a security professional, I have to disagree with your statements about these applications being “safe.” For the applications that send your text to the cloud for processing, you are basically installing a keylogger. The browser extensions are capturing everything you type, not just the things you want checked. Consider whether you really trust Grammarly not to lose all the text that you’ve typed in your browser.

    1. I’ve never lost text, I’ll don’t write legally sensitive materials. That said, I recently came across Antidote which works entirely on a desktop without internet access.

    2. I was going to ask the same thing. Grammarly is amazing at checking your writing…it is also fantastic at logging EVERYTHING YOU TYPE! Passwords, credit card numbers, personal info, everything. I wrote to ask about this and they broke off communication with me. I complete uninstalled and changed all passwords, BEWARE!!!! How about a list of non-cloud editors???

  28. Totally missing from the post is a suggestion with respect to the most appropriate choice if the writer prefers to write in real English rather than Yankish.

    While the English may have difficulty teaching their children to speak and write in their lingua franca, as we are reminded in Pygmalion, the Yanks never did learn to spell or speak in English and have always preferred to employ a patois slang

    Murricans (who are actually no more American than any of the other residents of the two continents) believe their bastardisation of real English is in accord with their “rugged individualism”. For this reason I would prefer to use a program based on the Queen’s English rather than U.S. slang.

  29. As a non english writer, I usually use grammarly. But since I write fictions, seems ProWritingAid is a good choice also. Thanks for the list.

  30. Grammarly is very glitchy to the point of annoying. Even with the ability to set writing goals, Grammarly’s algorithm makes suggestions that are not always appropriate. Grammarly acts as if I should never use the passive voice, which is one of the many irritating features for me. Grammarly makes it seem as if every piece I write, middle-schoolers and highschoolers should be able to understand.

    Another feature that causes premature baldness was using Grammarly to check my WordPress blogs. Grammarly makes a suggestion, but as you start to correct the mistake, Grammarly jumps to the next issue before you have a chance to finish your correction. You have to surf through your post to find where Grammarly interrupted your efforts to make the necessary corrections. Grammarly is packed with all kinds of bugs!

    I found this article looking for better grammar checking software. I’m disheartened to find Grammarly at the top of your list. I think I will have to shell out some money for a super, high-end grammar checker if Grammarly is considered the best by so many.

  31. Thanks for sharing this information. Whenever we write something at that time we have doubts in our mind, that writing is correct or not. For this reason, I use NOUNPLUS grammar checker tool for checking writings.

  32. I do not know if it’s just me or if perhaps everybody else
    experiencing problems with your blog. It seems like some of the text within your posts are running off the screen. Can somebody else please comment
    and let me know if this is happening to them too? This might be a issue with my browser because I’ve had this happen before.
    Many thanks

  33. Thanks for this review; there are several apps here I’d never heard of.

    I regularly use both Grammarly Premium and Pro Writing Aid Premium. Grammarly lacks many of the reports and features that Pro Writing Aid has, but Pro Writing Aid has its faults, so I use both.

    Grammarly’s biggest flaw, IMHO, is that it has a list of frequently overused words that it hammers you on. These are not necessarily words that you have overused, though. If you follow Grammarly’s rules, the words good, bad, big, small, large, huge, et al. would disappear. Grammarly’s readability check only covers a few sentences, rather than entire paragraphs. Though Grammarly will tell you if you have three consecutive sentences that have the same structure, it won’t tell you that you have three or more consecutive sentences that start with the same word. Grammarly does not check for long sentences nor for words that you have overused that are not on its list. It also is limited in the size of document you can enter; I’ve loaded an entire novel into Pro Writing Aid, but you can’t do that in Grammarly.

    Pro Writing Aid, on the other hand, has a poor understanding of U.S. English. Some of its rules are simply absurd, e.g. don’t use the word “holiday” because in the U.S. they use “vacation.” Uh, no, that’s not correct. And there are many others of that sort. Often Pro Writing Aid will label something as “UK spelling” when in fact it is a valid U.S. spelling as well, as supported by Merriam-Webster and Google Books Ngrams.

    Pro Writing Aid’s readability and consistency checks are near useless. Readability gives you no clue what’s wrong, only telling you that you should rewrite, and it has difficulty with short, terse sentences. The Consistency Check consistently flags capitalization and hyphenation inconsistencies even when those are used correctly.

    On top of those issues, it’s simply buggy. For example, in a text I’m editing, Pro Writing Aid complains that there’s a sentence that’s too long–38 words–when in fact the application has conflated three consecutive sentences to achieve that count.

    If I could find an application that had Pro Writing Aid’s features with Grammarly’s quality, I’d buy it. Until then, I’m still looking.

  34. Whitesmoke is all smoke and mirrors. More or less useless on a Mac. I was not able to get it to function like it’s described, and customer support did not respond to multiple inquiries. I deleted the app within a day. Complete waste of money.

  35. Helpful article!
    But I think some of them are not convenient on the phone device. When we writing an email, or send a short message, we don’t want to open a website to correct our grammar mistakes. There is an alternative to Ginger is AI Grammar Checker, which is already uploaded on the App Store and Google Play Store.
    AI Grammar Checker is based on the amount of real people error correction, which can make your writing more genuine and accurate. What’s more, it can provide detailed analysis including part of speech and example sentence, which is other grammar correction apps don’t provide.

  36. Hi, I’m the developer of AI Grammar, a grammar checker on Apple & Android smartphones, and hope to work with you. Can you give me your email or other contact information?

  37. Hemingway just doesn’t understand how search engines like Google rank my articles. Don’t get me wrong, I still use Hemingway every so often to make sure that the mechanics of my writing are up to par, but I’ve been relying on INK for all SEO Score more and more recently.https://seo.app/xXbUVFVV7

  38. It’s a beneficial article. Thank you for sharing.Hemingway just doesn’t understand how search engines like Google rank my articles. Don’t get me wrong, I still use Hemingway every so often to make sure that the mechanics of my writing are up to par, but I’ve been relying on INK for all SEO Score more and more recently.https://seo.app/xXbUVFVV7

  39. I am a high school special education teacher. I’m wondering if you think Hemingway would be a good teaching tool for students to use after Grammarly. I would like students to understand the mistakes they make, instead of having something automatically fix it for them. What are your thoughts? Do you have a better suggestion?

  40. I ordered a 2 year subscription to whitesmoke as part of a bundle I was only able to login once. It was annoying and inefficient. I didn’t bother again until near the end of my subscription to give them another chance to which I found there was no login and I had to contact customer DISSERVICE. The absolutely UNHELPFUL rep, Micaela, dragged out the ‘help’ process’ responding only once a day with further questions to ‘verify’ my subscription while prominently stating in each email “they’ll give me a 3 year subscription for only $99!”. Gee, your software stinks and I am not able to login into it and you’re doing NOTHING to fix that but you want me to spend $99?!?! How about you FIX MY PROBLEM! She did nothing to resolve the problem only extend the time until the next to last day saying ‘it’s expired now but BUY BUY BUY!’ I responded with I still have another day I paid for FIX IT! And again, she waited another day then replied with ‘we hope to have you back!’ Whitesmoke is aptly named because your money goes up in smoke and you get terrible service from a garbage product. Don’t let them blow smoke up your a$$ and avoid whitesmoke! I will never buy anything from this lousy company ever again and I suggest you don’t either.

  41. Hey,
    Very Nice and useful article, I think Grammarly is the best among all. I personally using this for many years.
    I also read your Grammarly Review article, in that you provide a very usefull detail of this software.
    Thanks for your valuable content.
