8 Best Grammar Checker Tools Of 2023

Grammar can be defined as the set of structural rules that governs the composition of words, phrases, and clauses in a natural language. Unfortunately, there are millions of people in the world with bad grammar. It hurts, but that’s the truth.

Wrong grammar can lead to several problems. Perhaps, the two biggest problems that arise from incorrect grammar are poor communication and bad first impression.

As an experienced writer, I have had the opportunity to thoroughly test dozens of English grammar checkers and proofreading tools. Today, there are a plethora of online grammar checkers for authors, bloggers, and writers.

To save your precious time, I’ve carefully handpicked eight of the best grammar checker tools. In addition to long essays, reports, and articles, these tools can also be used for writing error-free presentations, emails, and social media posts.

All these tools (except one) have free versions that provide enough features to correct common grammatical errors. However, if you are a professional writer, I would recommend you to go for the premium tool as it can correct tricky errors that are hard to spot manually.

8. CorrectMe


Price: Free
Platform: iOS

CorrectMe analyzes your text carefully to detect every minor mistake you made. It is specifically designed for iPhone and iPad devices.

Not only does it correct all your spelling and grammar mistakes, but it also provides smart recommendations to fix the problems. For instance, it suggests alternative words you can use to supercharge your writing skills.

The pro version of the app comes with additional features such as grammatical explanations. But I would recommend you to stick with the free version only.

7. GradeProof


Price: $10 per month
Platform: Browser Extension | MS Office | Google Docs

Gradeproof makes it easy to have immaculate articles, reports, and documents. It is packed with various useful features such as artificial intelligence-powered Eloquence Engine, advanced grammar error detections, and plagiarism checks.

The software refines your writing with informed grammar, spelling and rephrasing suggestions, and tracks crucial statistics about content such as grade level and readability.

The platform is easy-to-use and it works great, but the free version comes with basic features only. To use the advanced grammar engine, eloquence engine, and plagiarism checker, you have to opt for the premium version.

6. WhiteSmoke


Price: $59.95 per year
Platform: Windows | Mac | Browser Extension | MS Office

WhiteSmoke is an all-in-one solution – it includes grammar and spell checker, style checker, punctuation checker, translator, and built-in templates.

Instead of performing a word-by-word series of corrections, the software does a contextual analysis of your text, correcting errors in real-time. It also generates a review report that shows the overall rating of the written text.

However, the tool is not perfect. It detects some errors without a problem but ignores other glaring mistakes, such as the use of double negatives and passive voice. Sometimes, the program stops in the middle of reviewing, which is exasperating.

5. LanguageTool


Price: Free | €19 per month
Platform: Browser Extension | MS Office | Google Docs

LanguageTool is an open-source online grammar solution that detects errors in more than 30 languages, including English, German, Russian, French, Spanish and Polish. It can detect and fix grammatical and stylistic issues in content.

Like other grammar checkers, it offers a personal dictionary to keep a set of words that are not found in a standard dictionary, but might be a part of readers’ native language.

And since the software supports multiple languages, it takes into account the variations of those languages. For example, it takes care of the distinction between British and United States English while analyzing the text.

With the free version, you can check up to 2,500 characters in one go. The premium version allows 40,000 characters per check and detection of more than 1,500 other additional errors.

4. Hemingway App

Hemingway App

Price: Free | $19.99 (one-time fee)
Platform: Mac | Windows | Online Editor

The Hemingway App is named after the literature prodigy, Ernest Hemingway. It’s a minimalist yet powerful tool that aims to make your writing bold and clear.

Although Hemingway editor is not an in-depth grammar checker or writing coach, it can tighten up the style of almost any writer out there. It highlights wordy sentences, passive voice, adverbs, and complicated words in different colors.

The app has one-click integrations with WordPress and Medium blog. It also works alongside other editors, such as Microsoft Word, so you don’t have to copy-paste between different programs.

3. ProWritingAid

ProWritingAid - best grammar checker tool

Price: Free | $80 per year
Platform: Mac | Windows | MS Office | Browser Extension | Google Docs

ProWritingAid cleans up almost all types of write-ups by detecting spelling and grammar mistakes, contextual errors, and plagiarized content. It scans for elements like complex sentences, passive voice usage, vague wording, repetitiveness, and over-dependence on adverbs.

The tool is integrated with contextual thesaurus and word explorer that help you expand your vocabulary and express ideas more clearly.

The free version allows you to edit 500 words at a time, whereas the paid one has no word limit and provides 50 plagiarism checks per year.

2. Ginger


Price: Free | $20.97 per month
Platform: Mac | Windows | iOS | Android | Browser Extension

Ginger Software uses statistical algorithms along with natural language processing to improve written communications. The company claims that its language enhancement technology can correct written sentences with relatively high accuracy compared to conventional spell checkers. It can eliminate up to 95% of writing errors.

Ginger’s main feature is spelling and grammar checker that seamlessly work with different UIs. Contextual synonyms, advanced paraphrasing tools, text-to-speech functionality, and multi-language translation features could further enhance your writing experience.

While it is more accurate than other online grammar checkers, you should not rely solely on Ginger for accurate feedback. Sometimes, the tool (especially the browser extension) hangs without any reason and all the editing is lost.

1. Grammarly


Price: Free | $29.95 per month
Platform: Mac | Windows | MS Office | Browser Extension

Grammarly is currently the most accurate digital writing tool powered by machine learning and deep learning algorithms. While the free version offers critical grammar and spelling check services, the premium version gives suggestions about vocabulary, tone, clarity, delivery style.

It comes with an easy-to-use interface: grammar, spelling, and contextual errors are highlighted with an underline as you write. If you hover the cursor on the error, it will show you the correct word/phrase along with an explanation of grammar rules.
