Grammarly is a powerful spelling and grammar checker. It’ll help you find and fix more errors than any competitor. Thanks to its best-in-class AI writing assistant, it can also save you time writing and generating content. Our Grammarly review explains more.

I worked as an editor for a national newspaper, where it was my job to find and fix grammar errors in news stories before they went to print. I know first-hand how painful and embarrassing these mistakes can be… but it’s best not to let your fears hold you back from pressing publish. I’ve also spent years trying grammar checkers and writing tools to find the best one.

Several years ago, I tried the free version of Grammarly, a grammar and spelling checker for proofreading articles, book chapters, and blog posts. Since then, the product has evolved into a powerful writing assistant. It offers AI tools for anyone working with the written word. Today, I use this writing app to edit my work. I also rely on it to check articles by other freelancers I work with. It’s a vital tool for my business.

What Is Grammarly?

Grammarly is a popular grammar checker that was released in 2009. Over the years, it has evolved from a basic grammar checker into a plagiarism checker and advanced writing assistant powered by AI, unlike anything else on the market. It also enables writers to improve the readability of their works and rewrite sentences with a click. The Grammarly product is available via desktop and web apps and software plugins.

Using artificial intelligence, it scans a piece of writing and identifies writing mistakes, errors, and other issues. It can suggest grammar, spelling, readability, and tone improvements. It can also propose full-sentence rewrites and even generate content using promotes. It’s ideal for anyone who uses the written word as part of their job thanks to its various writing and editing tools. The company was co-founded by Ukrainian entrepreneurs Max Lytvyn, Alex Shevchenko, and Dmytro Lider. Today, Grammarly’s headquarters are in San Francisco.

Grammar Checker

Grammarly’s core feature is its grammar checker. It fixes grammar mistakes and punctuation errors of all types. The app or browser plugin provides real-time suggestions and guidelines on how to correct these mistakes. Examples include errant commas, misplaced apostrophes, and other common punctuation mistakes. Learn more about the differences between grammar and punctuation.

The premium version of Grammarly provides context to the flagged grammatical errors, including an explanation of the rule in question and additional examples. These are useful for improving your writing skills.

Spell Checker

Grammarly includes a robust spell-check tool. Using the business version, you can add words to a custom dictionary and even create a dedicated style guide. The spell checker covers variations including American English, British English, Canadian English, and Australian English.

Readability Reports

Grammarly writing insights
Grammarly writing insights are useful for self-editing

Grammarly scans clunky sentences, paragraphs and passages. It determines the ideal age group for a writing sample. It flags readability issues based on the following:

  • Word-count
  • Character count
  • Reading time
  • Speaking time

Then, using AI technology, Grammarly proposes more concise and clearer rewrites for the reader. To learn more, read our guide to the Grammarly Readability score.

Writing Style Improvements

Grammarly provides word choice suggestions and rewrites based on a piece’s ideal audience and intent. For example, Grammarly flags complicated words and clunky sentence structure if the intended audience is set to general and informal. Using AI, it can identify sections of your work to rewrite and provide multiple suggestions.

AI Writing Assistant

Grammarly includes a powerful writing assistant (previously known as GrammarlyGO). It works as a type of conversational chatbot. Click on the Grammarly icon and then ask it to make your writing more persuasive, confident, shorter, longer, and so on. It also provides information, rewrites parts of your writing, provides editing suggestions, and sources additional information.

It’s similar to ChatGPT but more suitable for writers and editors. You get a set amount of conversational credits per month. I found it exceptionally useful. The team recently announced an upgrade to its generative AI for office use. You can also use this assistant inside of Gmail to write email responses quickly and easily. I found this a real time saver.

Editing Reports

Grammarly offers downloadable reports you can send to another writer or editor. It provides word count, character count, and other readability metrics that writers and editors can use to improve a piece of writing. Editors and writers can customize these reports based on their preferred writing style.

Plagiarism Checker

Grammarly detects plagiarism by comparing a piece of writing to billions of web pages. It provides articles with plagiarism scores and links that an editor can check. This report helps verify other writers’ work, check your work, and find missing citations. It compares a scanned article against content that is freely available online. However, it does not compare to gated content or content behind a paywall. To learn more, read our guide about the best plagiarism checkers.

Style Guide

Grammarly Business Style Guide
A style guide is a key Grammarly Business feature

Grammarly offers a helpful style guide for collaborating with other writers. You can add custom words and terms to this style guide and ensure everyone writes out company terms consistently. This style guide is also helpful if you want to set rules around spellings and names.

Tone Rewrites

The Grammarly tone detector

Grammarly offers a tone detector that helps adjust an article or writing style. Essentially, a writer can decide if they want to sound. The tone detector helps tailor the style of business proposals, emails and even Slack messages. The Grammarly team offers this example:

The sentence “We are unsure of the potential impact of this project” sounds indecisive. The tone detector proposes to change this to “We need to find out the potential impact of this project,” which sounds more confident. You can pick a preferred tone for your writing, and Grammarly will tailor its suggestions. This feature is useful for editing emails on the fly. 

Citation Manager

A newer Grammarly feature is its citation manager. A writer can automatically create citations for their work at a click using the web browser plugin. It generates citations for APA, Chicago Manual of Style and MLA. This citation manager works on sites like Wikipedia and research sites like Pubmed, SAGE Journals, and Frontiers. The feature is in beta, but the team supports more publications and journals. Read our guide to the Grammarly citation manager.

Who Is This Grammar Checker Good For?

Grammarly is useful for native English speakers and those who don’t write in the English language that often. It also acts as another line of defense for professional writers. Its ideal audience includes:

  • Bloggers
  • Freelance writers
  • Content marketers
  • Copywriters
  • Authors
  • Journalists
  • Students
  • Academics, researchers, and essayists
  • Content publishers
  • Small business owners
  • Anyone who writes in English often.
  • Those who want access to AI writing tools

Grammarly provides English grammar-checking tools only. However, it includes settings specific to Canadian English, American English, British English, Australian English, and more.

How To Install Grammarly

First, you can create an account using your Google or Facebook account or your best email address. It’s OK to start with the free version. Now, you can use it in several different ways. You might also find our explainer on how to use Grammarly helpful.

Web App

You can access the Grammarly web app via app.grammarly.com. Then, paste a piece of writing directly into the web app. It’ll scan your writing and propose fixes. Alternatively, you can upload a rich text document into the web app and check it. You can download or copy and paste the results into your writing app.

Desktop App

You can download a desktop app for Windows or Mac. These apps require internet access to use. The app works in the background and checks any piece of writing for issues and mistakes. The Grammarly icon appears when you’re editing and writing. Click on it to scan a document in Microsoft Word for errors and other mistakes.

Browser Extensions

Grammarly for Chrome
Grammarly is available for most browsers

Grammarly excels thanks to its popular Chrome, Firefox, Safari, and Microsoft Edge plugins. After you install the plugin, please log in to your account. Now, Grammarly automatically scans pieces of writing in your web browser.

You can use it like a pop-up to check emails in Gmail, your latest social media posts, and more on the fly. Grammarly Chrome and other extensions help check emails, social media posts, and anywhere you write online. Learn more about how to add Grammarly to email.

Microsoft Office Plugin

Grammarly offers an officially supported plugin for Microsoft Office. Once installed, you can check and fix an article, report or email directly inside Microsoft Word or Outlook.

Grammarly Keyboard

Grammarly includes an official smartphone keyboard app for iOS and Android devices. Once activated, the keyboard app checks your writing as you compose a text message or email. It helps fix mistakes while working on the go. It also includes intelligent predictions to speed up typing.

The keyboard is customizable, too. It’s possible to set up your iOS keyboard layout with your preferred English language keyboard, including AZERTY, QWERTZ, COLEMAK, or DVORAK. You can also use Grammarly indirectly with other apps, assuming you are comfortable with the desktop app. Our resources below explain more:

Is Grammarly Easy To Use?

Thanks to its proliferation of apps and plugins, Grammarly is easy to use wherever you write. It scans up to 100,000 characters in real-time and proposes fixes and suggestions. It offers possible solutions and explanations for potential mistakes. You can filter through suggestions based on their importance or score. Then, you can accept or reject requests with a click. Grammarly helped me identify the following:

  • Typos
  • Confused prepositions
  • Overuse of the passive voice
  • Wordy sentences
  • Incorrect comma usage
  • Repetitive words
  • Punctuation errors
  • Common writing and grammar mistakes like misplaced apostrophes
  • Spelling errors
  • Lengthy sentences
  • Broken grammar rules

As Grammarly provides context to each fix (based on its Handbook), it’ll help you improve your writing skills rather than simply offering fixes.

Accuracy

Grammarly Accuracy Test
We tested Grammarly against traditional grammar checkers

Grammarly is accurate for most types of writers. I tested Grammarly extensively against a series of other grammar checkers. For issues, I checked blog posts, web copy, emails, and even book chapters. In my tests, it caught more mistakes than a traditional spelling or grammar checker bundled with an operating system or writing app.

Although some competitors were comparable in accuracy, Grammarly is the fastest and easiest to use. It’s particularly good for editing non-fiction and professional writing, for example, articles, emails, blog posts, web pages, presentations, etc.

Writers with more specific needs, such as genre fiction authors, should tailor Grammarly’s rules and settings and add custom words (e.g., character names) to improve accuracy. It’s also a good idea to set the correct goals inside of Grammarly as these affect its suggestions regarding delivery and engagement.

The caveat is that no tool or grammar checker is 100% accurate. It’s up to you, the writer, to decide whether to break a grammar rule or ignore a suggestion because of the audience, writing style, and subject matter.

If you’re on a budget, install the free browser extension and test it yourself. It’s ideal for writers with a minimal budget for writing tools. The free version contains a basic grammar checker. It lacks an advanced grammar checker, a plagiarism detector, and vocabulary enhancement suggestions.

That said, it’s still worth using.  It underlines potential grammar mistakes in red and proposes fundamental rewrites and fixes. You can also switch between US, British, Canadian, and Australian English. It should catch more errors than a basic grammar or spellchecker; you can try it without spending money.

Grammarly Premium

When you’re ready to upgrade to the paid version, Grammarly Premium contains several additional checks and tools for those who regularly write and publish content online. It also provides additional writing insights and an ability to set writing goals. It also finds and fixes more mistakes than the free version. The best Grammarly premium tools include:

  • The plagiarism report
  • Overused words
  • Inappropriate tone
  • Readability scores and reports
  • An advanced writing assistant
  • GrammarlyGO: its proprietary AI tool 

You can upgrade to Grammarly Premium for a month and cancel when you’re done. You can also upgrade for the entire year if you use it regularly. Check out our Grammarly tips and tricks guide to get more value from your subscription.

Grammarly writing goals
Setting writing goals in Grammarly

Before using Grammarly to edit a longer work, it’s a good idea to set a writing goal. You can set these goals based on your:

  • Intent, e.g., inform, tell a story or describe
  • The audience, e.g., general or expert
  • Style, e.g., formal or informal
  • Emotion, e.g., mild or strong
  • Domain, e.g., academic, business, or technical

The premium version of Grammarly delivers additional insights based on these goals. I found this feature helpful in editing technical documentation, whereby I assumed the audience was knowledgeable about the topic. Next, Grammarly surfaces issues to fix via five key grammar checker reports alongside its plagiarism detector.

1. Correctness

Grammarly underlines grammar and spelling mistakes in red and proposes fixes. Expect to use this report the most. After using this grammar checker on several articles and book chapters, I discovered I have a bad habit of ending sentences with prepositions. I’m also guilty of using the occasional squinting modifier. These are finer grammar points, but knowing my bad habits helped improve my writing.

The built-in grammar checkers in Microsoft Word and Google Docs didn’t provide me with these insights. I also particularly like the “Accept all suggestions” feature. This enables me to review several writing suggestions in a document and accept or reject them all at once. If you use this time-saving feature, don’t forget to review the suggestions and changes. 

2. Clarity

See the proposed rewrite to the side; I can apply them with a click. Grammarly reviews a piece of writing for clumsy and awkward sentence structure. It then underlines issues in blue. It also scans for instances of the passive voice.

Using AI technology, Grammarly proposes rewrites and other fixes. Judge these recommendations based on your audience and style guide; not all are relevant. That said, I was impressed by many of these recommendations. Use this report after you’ve fixed grammar mistakes.

3. Engagement

Grammarly reviews a piece of writing for challenging or hard-to-understand terms and overused words. It highlights them in green. It also looks for clumsy sentences. Use this report to polish your writing by finding better synonyms.

4. Delivery

Grammarly reviews a piece of writing based on your preferred tone and audience. It underlines issues in purple. I didn’t get as much value from this report for emails and other short-form works. However, it’s a nice addition if you want to spend some extra time copyediting a piece before submission or publication.

5. Style

It reviews a piece of writing based on your company style guide. It highlights issues in grey. Use this report if you work with freelancers and have a house-style guide. Learn more about style guides.

6. Plagiarism Detector

The plagiarism report is one of my favorite Grammarly tools. It’s premium only. Grammarly scans a piece of writing, scans the web, and highlights potentially plagiarised content with links. This tool appeals to college students and essayists who are concerned about citing too heavily from their sources without proper attribution. It’s ideal for those writing academic content regularly. It helps review a peer’s work and check an essay for accidental plagiarism.

The Grammarly plagiarism detector is also helpful if you’ve written an article and can’t remember your sources. Writers can check if they’ve inadvertently copied text from research sources without citing or linking correctly.

You can also check if a freelancer is providing you with original content. I also sometimes use this detector to check if someone has plagiarised popular articles from this site so that I can issue DMCA takedown requests.

7. App Actions

Grammarly now works with multiple apps. You can create Asana tasks, browse Unsplash and GIPHY for images, search for Confluence pages and access Google Drive inside of Grammarly. It also works with Microsoft Office 365. This makes it much more useful for content creators and anyone using it for work.

Areas for Improvement

Grammarly isn’t perfect. It could be improved in several different ways. The current price of $30 per month is expensive for writers on a budget. I’d also like to see the following:

  • Support for other languages beyond English
  • A free trial for the plagiarism checker so users can see how valuable it is

Grammarly Competitors

Grammarly has been around since 2009 and is a well-known grammar-checking tool. However, several key players are popular with writers and small business owners. The most popular include Word and Google Docs, ProWritingAid, Microsoft Editor, Ginger and Linguix. We tested it against these extensively but found Grammarly to be more accurate, easier to use, and includes a more powerful AI assistant.
