What is Grammar Checker?

Grammar Checker is a free online tool that uses artificial intelligence to identify and correct grammar, spelling, and punctuation errors in your writing. Simply paste your text into the editor or type directly, and the tool highlights mistakes with explanations for why they're incorrect. It's designed for anyone who writes: students working on essays, professionals drafting emails and documents, content creators polishing blog posts, and non-native English speakers who want to improve their writing accuracy. The tool works entirely in your browser with no sign-up required, making it accessible and straightforward to use.
