Grammar Checker

Paste any block of text and get it proofread by AI — a corrected version plus an itemized list of every grammar, spelling, punctuation, and style issue it found, and why each one was flagged.

How to use it

1. Paste the text you want checked (10 to 20,000 characters).
2. Click Check Grammar.
3. Review the corrected text, the highlighted diff view showing exactly what changed, the issues found list, and the issue count.

What it checks

• Grammar — subject-verb agreement, tense consistency, article/preposition misuse, and similar structural errors.
• Spelling — misspelled words.
• Punctuation — missing or misplaced commas, apostrophes, periods, and the like.
• Style — wordiness, awkward phrasing, and clarity issues that aren't outright errors but read better fixed.

Each flagged issue lists the original snippet, the suggested fix, and a short reason — so you can see exactly what changed instead of just trusting a rewritten block.

Tips

• This proofreads what you pasted — it fixes wording, not facts, and doesn't add outside information.
• For a result you can share or embed without regenerating it, copy the output text — like every AI-generated tool on this site, the result isn't reproducible from a shared link (it's non-deterministic, so a link would just spend credits regenerating a different answer).
• Need to reword an already-correct passage rather than fix errors in it? Try Article Rewriter instead.

Is my text stored anywhere?

Your pasted text is sent to an AI provider to generate the corrected version and issue list, then discarded — it isn't logged, stored, or used to train anything. See the third-party data badge above the tool for details.

Does it catch everything a human editor would?

It catches the common, obvious issues reliably, but it's a probabilistic check, not a certified proofread — for anything high-stakes (a contract, a thesis), still have a human give it a final pass.
