About this tool

Most grammar checkers keep your writing on their servers. This checker sends only the text you paste, once, to the free public LanguageTool API — no account, no document storage, no watermark on results. It catches subject-verb agreement, article mistakes, common confusions (their/there, its/it's), punctuation and British/American spelling. Click any suggestion to apply the fix, then copy the clean text.

FAQ

Is my text stored anywhere?

No. The text is sent once to the free LanguageTool API to compute corrections; this site stores nothing and LanguageTool's free public API does not keep text.

Which languages work?

English (US/UK) is default; auto-detect covers 25+ languages on the free tier.

Is there a length limit?

The free public API accepts ~20,000 characters per check — split longer documents.

Does it check plagiarism?

No — use our Plagiarism Checker for that; this tool checks correctness, not originality.

How fast is it?

A few hundred words are checked in about a second.

Can I use it offline?

No — grammar checking needs the language model, which lives on the free API.
