Looking for the best grammar checker in 2023?
If not, you should be.
After all the work you put into your writing, one grammar error — one simple, stupid error — can undermine it all.
That’s why smart freelance writers, marketers, and students use grammar checking software to keep their writing as professional, SEO-friendly, and error-free as possible.
But which grammar checker is right for you? That’s what we’re going to help you figure out.
Let’s jump in.
Grammarly (affiliate link) is a powerful grammar checker that provides tools to help you improve your writing. It’s a writing assistant that follows you almost everywhere you want to write.
This proofreading tool checks your work and suggests corrections for errors. By providing an explanation for those corrections, it helps you learn from your mistakes.
The free version will help you with spelling errors and basic grammar mistakes and could be adequate for casual writers.
Grammarly Premium catches advanced grammar and punctuation mistakes and contextual spelling errors. It provides suggestions for improvements in sentence structure, word choice, and readability.
It even allows you to set goals for tone and intent, an experimental function, but it can be useful.
Pros of Grammarly
- Easy to use grammar checker tool with a clean and simple user interface.
- Unlimited plagiarism checks with Grammarly Premium.
- The flexibility of multiple formats. It’s available as a web-based online grammar checker tool, web browser extension, desktop app, an add-on for Microsoft Word, or as a keyboard for your mobile devices.
Cons of Grammarly
- The free version has limited features and will catch fewer errors than the premium version. You’ll need to upgrade to Grammarly Premium to gain access to Grammarly’s best features.
- Google Docs integration is still in beta. You’ll need to copy and paste your text into the app to get the full benefit of your premium subscription.
- The Grammarly app can be a bit aggressive in suggesting errors. For example, Grammarly loves commas even when they may interrupt the flow of a sentence.
How Much Does Grammarly Cost?
You can try Grammarly (affiliate link) for free.
The Grammarly Premium upgrade has three options: $29.95 per month billed monthly, $19.98 per month billed quarterly ($59.95), or $11.66 per month billed annually ($139.95).
The free version of Grammarly will catch typos and complete a basic grammar check. The premium version will intercept advanced errors like plagiarism and passive voice detection while also providing feedback to help you improve your writing.
As noted in our in-depth review of Grammarly, it is an excellent choice to improve your writing skills and keep your writing error-free, and it’s a unique gift you can give someone who writes a lot.
Ginger is an online grammar checker tool that corrects “all types of grammatical mistakes, including punctuation, sentence structure, and style.” It also provides translation into over 40 different languages. For example, you can write in German and then translate it into English.
The free tool is limited to 350 characters. However, if you are willing to sign up for the Ginger grammar checker, you can get a far more robust Google Chrome extension for free. This will give you access to the Ginger Writer app, where you can copy and paste your text to find any errors.
Ginger has a mobile app, Ginger Keyboard, to catch spelling mistakes in texts, emails (Outlook, Gmail, etc.), and social media posts. It works with MS Word, but not Google Docs.
Pros of Ginger
- Built-in langauge tool provides translations for over 40 languages.
- The free version includes three writing tools— an editing window with translations, a dictionary, and a thesaurus.
- The premium version includes a “personal trainer” to improve your English. The trainer provides “personalized practice sessions based on your own writing” and is like having a virtual writing tutor.
Cons of Ginger
- Multiple steps to work through your text in the Ginger Writer app. First, you have to hover over mistakes to find out what is wrong. Then you need to click a text box to either accept or reject the error. There is no sidebar (like Grammarly), listing each potential grammar mistake.
- It provides minimal feedback about errors in the free version.
- Ginger is not compatible with the Mac OS or Google Docs.
How Much Does Ginger Cost?
If you need more than the free version, upgrading to Ginger Premium has three options. $20.97 per month billed monthly, $7.49 per month billed annually ($89.88), or a two-year subscription for $159.84. Note these prices reflect a special promo discount of 30% off all plans.
The free version of Ginger offers basic spell check and grammar checking. You’ll need to upgrade to the premium version for more advanced grammar checking or to see an analysis of your errors.
If English is your second language, or if you wish to switch between languages while also double-checking your grammar, Ginger is a great grammar checker app.
3. Hemingway Editor
The Hemingway Editor is a style checker that provides feedback to keep your writing easy to read. Following the style of Hemingway, it aims for clear, simple sentence structures — something every freelance editor and writer can appreciate!
It labels complex sentences as either “hard to read” or “very hard to read.” This way, you can rewrite overly complex sentences that might trip up your reader.
It also flags the use of the passive voice, excessive adverbs, and complex phrases.
Pros of Hemingway Editor
- The online version is free.
- If you get distracted when you write online, an inexpensive desktop version is available to help you avoid temptations.
- Alerts you to writing that is either hard to read or understand that you might not catch on your own.
Cons of Hemingway Editor
- You need to copy and paste your text into the app for it to review your work, and it won’t preserve your formatting.
- It doesn’t provide suggestions on how to edit complex sentences. Fixing your text is up to you.
- Following every suggestion could cause your writing to become TOO simplistic. Although you always want to be clear in your writing, sometimes, a bit of complexity is appropriate.
How Much Does Hemingway Editor Cost?
The online version is free. If you want to work offline, there is a desktop app available for $19.99.
Hemingway Editor Review
The Hemingway Editor is not a replacement for grammar check software. But it is an excellent complement to these tools.
This app helps you enhance your readability and avoid the stumbling blocks that could cause your readers to bail. It can help ensure your writing gets read.
4. After the Deadline
After the Deadline is an open-source grammar checking tool.
To quickly check a piece of writing for free, you can copy and paste it into the interface at polishmywriting.com. This tool provides feedback on spelling errors and provides grammar and style suggestions, as shown below.

After the Deadline Review
If you’re a blogger who composes posts directly in WordPress, this free grammar checker can cut down on potential errors.

Cons of WhiteSmoke
- The free version is limited to 250 characters and is currently available as a web application only. The “free WhiteSmoke toolbar for Chrome” noted on their website was unavailable.
- The web version works with web browsers only. You’ll need to upgrade to Premium to get support for all other formats.
- No option for a monthly subscription. You’ll have to make the commitment to an annual subscription.
How Much Does WhiteSmoke Cost?
The Web version (browsers only) is $5 per month billed as $59.95 annually.
The Premium version is $6.66 per month, billed as $79.95 annually.
Note: these prices reflect a 50% discount.
If you need a lower-priced grammar app (while the 50% discount is valid), WhiteSmoke can save you money. But you have to be willing to take a chance as there is no free trial, although they do have a 31-day money-back guarantee.

It’s available in many formats:

Pros of LanguageTool
- It supports more than 25 languages besides English, including Spanish, French, and Russian.
- It has a personal dictionary you can customize.

- The free version limits you to 20,000 characters per check (a word count of around 3,400 words, although characters per word vary significantly).
- The premium version limits you to 40,000 characters per check, so you’d need to check very long documents in pieces.
How Much Does LanguageTool Cost?
If you need more than the free version offers, LanguageTool Premium has three options. $19 per month billed monthly, $13 per month billed quarterly ($39), or $4.92 per month billed annually ($59).
LanguageTool is the right choice if you are looking for a basic spell checker with grammar checking capabilities. And it’s not just for English speakers — not only is there a free version, but LanguageTool can support other languages too.
However, languages are supported to different degrees. Check this table to determine how well supported your language is.
ProWritingAid (affiliate link with 20% off code) is one of the more robust grammar checkers besides Grammarly. It will tell you if you’ve made a grammatical mistake, punctuation error, spelling error, style gaff, and it provides in-depth feedback on your writing.
It has over 20 different writing reports, which you can click on one at a time, so you don’t need to do all your editing at once.
For example, you could first fix grammar, spelling, and style errors. Then you could select the report to change up any repeated words and phrases.
Next, you could run a report to identify cliches, and then follow up with a report on sentence structure issues.
Going through these reports will help you improve the quality of your writing skill. You can read through their suggestions and implement what works for you.
Pros of ProWritingAid
- The variety of reports provided are excellent for self-editing.
- A lifetime subscription offered at a reasonable price.
- Integration with Scrivener is available.
Cons of ProWritingAid
- The free trial is limited to up to 500 words in the online tool.

How Much Does ProWritingAid Cost?
Upgrading to ProWritingAid Premium has four options: $70 per year, $100 for 2 years, $140 for 3 years, or a lifetime subscription at $240.
If you want extensive feedback on your writing, ProWritingAid is a solid choice. You have the option to view reports one at a time to avoid becoming overwhelmed by the quantity of feedback.
For fiction writers, the unique reports to check your pacing and dialog could be valuable.
8. Google Docs (or Microsoft Word)
Both Google Docs and Microsoft Word (Microsoft Editor) include built-in grammar checkers. They allow you to fix your basic spelling and grammar errors for free.
As you type, a red squiggle under the word alerts you to spelling errors when you make them. A blue squiggle indicates potential grammar errors.
Right-click for suggested corrections (unless you are way off, in which case, you’re on your own!), and select the ones you agree with.
Google Docs at work:
Microsoft Editor also provides a quick snapshot of your text’s readability.
Pros of Google Docs (or Microsoft Word)

- Customizable dictionaries are available in both programs.
Cons of Google Docs (or Microsoft Word)

How Much Does Google Docs (or Microsoft Word) Cost?
There is no extra expense, the grammar and spell checkers are part of the software.
Google Docs (or Microsoft Word) Review
If you write using these word processors, their free spelling and grammar checkers provide the first line of defense against basic errors.
To correct more advanced errors, and get feedback on your writing, you’ll want to use a dedicated grammar checker.

Google Docs does provide translation capabilities, something Grammarly doesn’t have.
So Which One is the Best Grammar Checker?
The best grammar checker for you depends on the features you need and on your budget.
There are free grammar checkers and free versions of premium grammar checkers, and those may be enough for casual writers. But they are limited compared to the premium versions.
Anyone dedicated to the craft of writing should strongly consider a full-featured premium grammar checker.
Grammar checkers are not a replacement for a human proofreader or an editor. They help cut down significantly on errors but are not enough by themselves. Always use human eyes for final proofreading.
Also, don’t rely solely on the suggestions provided by these grammar checkers. Instead, use your own judgment.
The best grammar checkers will significantly cut down on the number of errors you make. And error-free writing is essential.
So select a grammar checker to try and get started today.
