Overview

Why use our Grammar Checker?

This AI grammar checker reads the whole sentence before it touches a word. It weighs context, then corrects grammar, spelling, punctuation and clumsy phrasing in a single pass, while your meaning and tone stay exactly as you wrote them.

Every fix appears highlighted next to your original text, so you can see what changed and why. There is no sign-up, no quota and no watermark. Paste your draft, click once and copy clean, error-free writing in seconds.

Context-aware grammar correction

Most checkers flag words one at a time. This AI grammar checker reads the full sentence first, so it catches subject-verb agreement, verb tense, articles and prepositions that a basic spell-checker misses. Paste your text, press Check grammar, and the corrected version comes back in seconds.
02

Grammar, spelling and punctuation in one pass

It repairs typos and misspellings, fixes commas, apostrophes and quotation marks, and resolves run-on sentences, comma splices and sentence fragments. Clumsy phrasing gets smoothed at the same time, so you never need a separate tool for each error type.
03

See every edit, side by side

The result sits next to your original with each change highlighted. You can scan exactly what the corrector fixed, learn the rule behind it, then copy the clean text or run the check again on a fresh draft.
04

Your meaning and tone stay intact

This is a corrector, not a rewriter. The tool keeps your wording, voice and formatting, including line breaks, and never paraphrases. It mends what is broken and leaves the rest of your draft exactly as you wrote it.
05

Proofread in 30+ languages

Check grammar, spelling and punctuation in English, Spanish, French, German, Portuguese and many more. The corrector adapts to the language you paste and applies its rules automatically, so there is nothing to configure.
06

Built for any kind of writing

Students proofread essays and assignments, professionals tighten emails and reports, and marketers polish web copy and product descriptions. Anyone writing in a second language gets a quick, reliable check before they hit send. Run one or two paragraphs at a time for the sharpest review, and when a sentence needs rewording rather than a fix, send it to our Paraphrasing tool.
