Grammar Checker

Grammar Checker is a free online writing tool that finds grammar, spelling, punctuation, and style issues in any text you paste. It's designed for quick checks: paste a paragraph from an email, essay, article, or social post, and see highlighted suggestions before you publish or send. There's no sign-up step, so you can start proofreading immediately in your browser.

The tool combines several checks into one view: it scans for typos, repeated words, agreement errors, comma and period problems, and sentence fragments. Its AI suggestions look at full sentences rather than isolated words, so you can review context before accepting an edit. You always keep control — nothing is rewritten automatically. A built-in AI detector, thesaurus, and title capitalizer sit alongside the main editor for extra polish.

Grammar Checker is useful for students checking essay paragraphs, professionals cleaning up emails, or anyone who wants a fast second pass on short to medium-length drafts. Because it works entirely in a browser on any device, it fits easily into existing writing habits without extra software or subscriptions.
