Free Grammar Checker

This spell-check and grammar check catches grammatical errors, spelling mistakes, punctuation problems, and issues of tone and style such as wordiness, passive voice, and awkward phrasing. Each correction comes with a plain-English explanation so you learn as you edit.

Paste or upload your text, then click Check Grammar. This AI-powered check returns a corrected version, a list of corrections you can accept or ignore individually, and a writing score in seconds.

It checks full sentences and paragraphs together rather than one at a time, so corrections account for the surrounding context instead of an isolated line. That makes it suited to whole essays, emails, and reports, not just single sentences.

The best grammar checker for you depends on what you need it to do. If you want free daily checks with no account and a direct handoff into paraphrasing or humanizing tools, this one is built for that. If you need real-time checking inside a word processor, a dedicated writing app might suit you better.

Our AI is highly accurate across grammar, spelling, and punctuation. Dialect differences, such as American versus British English, can occasionally trigger a suggestion you don't need, so review each correction before copying your text. Reviewing suggestions over time can also improve your writing skills.

Yes. Your text is processed securely to generate corrections and is never stored or shared. You can check sensitive documents with confidence.
