About this grammar checker
A grammar checker helps you catch mistakes before anyone else sees them. This free tool scans your text for spelling errors, punctuation problems, capitalization issues, and common grammar slip-ups, then shows each issue with a suggested correction.
It is ideal for emails, essays, social posts, and everyday writing where you want a quick proofread. For deeper, context-aware rewriting — like fixing subtle verb agreement or restructuring awkward sentences — our AI writing tools go further than a rule-based checker can.
The tool is free with no sign-up. Your text is checked and not stored, so your writing stays private.
