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

If you're running a business, check out our Grammarly Business review.

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 missing citations

How Much Does Grammarly Premium Cost?

  • Grammarly Premium monthly subscription costs $29.95 per month.
  • Grammarly Premium quarterly subscription costs $19.98 per month, billed as one payment of $59.95.
  • Grammarly Premium annual subscription costs $11.66 per month, billed as one payment of $139.95.

Grammarly also 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.

Using Grammarly as a Grammar Checker

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 tool.

However, Dupli Checker and all free plagiarism checkers place a limit on how much 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.

Grammarly writing insights
Pros
  • Easy to use
  • Powerful online spelling and grammar checking
  • Great writing insights
Cons
  • Expensive for new writers
  • Personal dictionary and style guide are Grammarly Business features

2. ProWritingAid

WHY YOU SHOULD BUY
ProWritingAid
Accurate and affordable
  • ✓   "Goals" feature helps you focus on impactful changes
  • ✓   Over 20 powerful writing reports
  • ✓   In-app videos and explanations help you learn as you edit

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.

Using ProWritingAid as a Grammar Checker

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 useful 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
  • Affordable
  • Accurate
  • Powerful self-editing reports
  • Suitable for fiction writers and Scrivener fans
Cons
  • Slower than Grammarly
  • No mobile version

Grammarly and ProWritingAid are the two most popular grammar checkers available today. If you'd like to learn more about the right choice for your work, read our ProWritingAid vs Grammarly comparison.

3. Ginger

GRAMMARLY ALTERNATIVE
Ginger
Affordable alternative to Grammarly
  • ✓   Useful personal dictionary
  • ✓   Good for non-english writers
  • ✓   Insightful writing reports

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… but none for Google Docs yet.

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. 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.

How Much Does Ginger Software Cost?

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.

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!

It also didn't suggest sentence improvements like Grammarly. And I ran into several other usability issues. As a Mac user, I couldn't get this app to fit into my workflow. To learn more, read our Ginger vs Grammarly comparison.

Ginger Review
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
  • Mac app is barebones
  • No support for Google Docs

4. WhiteSmoke

GRAMMARLY ALTERNATIVE
WhiteSmoke
Relatively accurate
  • ✓   Useful personal dictionary
  • ✓   Suitable for businesses
  • ✓   Cheaper than other grammar checkers

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 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 cost

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
  • Slower than Grammarly

5. 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 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

6. 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 writing.

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
  • Lacks many writing reports

7. 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
  • Free
Cons
  • Not a replacement for a dedicated grammar checker
  • Lacks insightful writing reports

8. 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
  • Free
Cons
  • Accessible only via a web browser.
  • Not as powerful as other grammar checkers

9. 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
  • Easy to use mobile app
  • Useful for non-English writers
  • Free
Cons
  • Less features than other grammar checkers
  • Slow

10. Writer.com

Writer.com is a newer entry. It's not an app for a novelist, a single writer maintaining a blog, or an essay writer, etc.

Instead, it’s ideal for marketing teams, brand agencies, social media managers, sales and HR departments, PR, and similar business-related writing tasks.

Like Grammarly Business, the tool offers a dedicated style guide and supports secure collaboration. It's also cheaper than Grammarly.

Unlike other tools featured here, it works on nearly anything that companies may use, including sales platforms, content management systems, everyday writing apps like Microsoft Word or Google Docs.

It also supports common email clients like Gmail, and all major social media platforms like Twitter, Facebook

It'll be interesting to see if Writer.com can capture the same market share as Grammarly.

 How Much Does Writer.com Cost?

  • It starts at $11 per month, per user

Writer.com Review

Writer.com has the potential to compete with Grammarly. It's accurate and has some business security measures that other grammar checkers lack like SOC2 and HIPPA compliance.

I particularly liked its style guide and user interface. However, it's less well-known. It's also less suitable for fiction writers and lone writers. I recommend considering this tool if Grammarly business is too expensive for your company.

Pros
  • A premium quality, styleguide checker
  • Allows business to build content rules
  • Cheaper than Grammarly
Cons
  • Not designed for fiction writers or single users
  • Takes time to set up properly

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 I 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. This round-up previously featured After the Deadline. However, I removed it after the discontinued support for platforms like WordPress.

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. 

Paid Vs Free Grammar Checkers

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

However, I recommend 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.

How to Use A Grammar Corrector

A grammar corrector is a useful writing tool for writers, bloggers, essayists, business people and anyone who communicates with the written word.

They are also helpful if you spend time editing the work of other writers or need to check something in a hurry, for example, at work or before a deadline.

Unlike the standard grammar and spell checker in MS Word or Google Docs, these tools perform a more in-depth grammar check. You can even create downloadable editing reports! Basically, a good english grammar corrector should help you fix:

  • Common spelling errors
  • Instances of the passive voice
  • Clunky and hard to understand language
  • Other common grammar errors like misplaced apostrophes, a misused word or incorrect punctuation

To use one:

  • Write your social media post, email, blog post, article or book chapter as normal.
  • Fix any spelling errors as you go.
  • Copy the text and paste into one of the grammar correctors in this round-up.
  • Change the language of your tool to US or British english. Now, the spelling checker will highlight potential localization issues.
  • Review the highlighted grammatical mistakes and associated suggestions.
  • Check if your work is properly cited with links and original content. Some of the premium tools in this guide include tools for this.
  • Alternatively, download the grammar suggestions and localized spelling suggestions as a report and send it to a writer or editor on your team to fix.

Remember, these tools aren't a complete replacement for a human proofreader, particularly for longer projects. 

Most grammar checking tools have features comparable to Grammarly. But, there are some crucial differences as well.  Let’s see what they are.

How Grammar Checkers Support Proofreading

As you know, proofreading is a different skillset 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 and incorrect word choices.

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 backwards (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. 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.

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.

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.

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 apostrophes or commas.

Reverso vs. Grammarly

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

the Best Grammar Checkers You Can Buy

Please remember, always work with a human proofreader for longer works, 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 work. 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.
