About

What is an Online Grammar Checker?

A grammar checker — also called a grammar correction tool, spelling corrector, or sentence checker — analyses written text for errors in spelling, grammar, punctuation, and style. Unlike basic spell checkers, this tool analyzes context — not just individual words — to catch errors that rely on meaning rather than dictionary lookup.

This tool checks grammar across 11 languages and provides a quality score, issue breakdown by category, and a corrected version of your text. For longer documents, pair it with our Word Counter to track length alongside quality, or use our Keyword Density Checker to optimise SEO content after proofreading.

🔒 Privacy

Your text is processed for grammar analysis only — it is not stored, logged, or used for training. Results are returned directly to your browser.


Why it matters

Why Grammar Mistakes Matter
