What is Grammar Checker?
A grammar checker analyzes your text for grammar errors, spelling mistakes, and style issues.
This tool uses pattern-based detection to catch common problems like double spaces, missing capitalization after periods, repeated words, confused words (their/there/they're), and 17+ common misspellings. It runs entirely in your browser -- your text is never sent to any server.
