About Grammit: AI Grammar Checker

Free grammar checker that finds and corrects a wide range of errors that a regular spell checker may miss. Grammit gives you suggestions to polish your writing. Errors are underlined automatically as you write, and corrections can easily be applied individually or all at once. Top Grammit benefits: ★ Spelling check Grammit catches spelling mistakes (“peice” will be corrected to “piece”), capitalization errors (“nasa” will be corrected to “NASA”), and other typos. ★ Grammar check Grammit catches all sorts of grammar mistakes such as “Your” vs “You’re” or “It’s” vs “Its”. ★ Correct other mistakes Grammit’s AI correction engine can catch other mistakes. Did you accidentally write "The theory of evolution was developed by Charles Dickens"? Grammit will correct that to "Charles Darwin". ★ 100 languages supported Grammit supports many languages. It also supports variants of common languages such as British English or American English. ★ Rephrasing and drafting support Ask Grammit to rephrase your writing to make it more professional. Or have it draft an email for you or help you brainstorm ideas. ★ Works everywhere you work Whether you're writing emails, social media posts, or chat messages, Grammit can help you. ★ Local corrections run on your computer Select between Grammit’s Local AI or Cloud AI models to control where your data is corrected. Other grammar checkers (*cough* Grammarly, *cough* Quillbot, *cough* LanguageTool) may require using a cloud service to correct. Grammit can check your writing directly on your computer using a Local AI model. ~~~ If you're tired of mistakes slipping through, it's time to switch to Grammit. It’s free! When you use Grammit’s on-device Local AI, all grammar checking, rephrasing, and chats with Grammit happen entirely on your computer without your writing being sent to external servers. If you use our Cloud AI model, we do not retain your writing, nor do we use it to train models. Try Grammit today to see your writing improve.
