About Free Grammar Checker

Free Grammar Checker scans any pasted text for real grammar, spelling, punctuation, and style issues using the open LanguageTool proofreading engine - completely free, with no API key required. Every issue shown comes with the exact rule that flagged it and, where available, a suggested fix you can apply with one click directly in the editor. It never rewrites your text silently - the corrected version only changes when you accept a specific suggestion. If AI is configured on this site, you can also generate a fully polished rewrite of your text in a tone of your choosing (Professional, Casual, Concise, or Persuasive) once you have reviewed the flagged issues.
