Check grammar, spelling, punctuation, and style in your writing. Improve your text with instant feedback.
A grammar checker is an automated proofreading tool that scans your text for grammar errors, spelling mistakes, punctuation problems, and style issues. It works by comparing your writing against language rules and common error patterns, then highlights issues and suggests corrections. Our free grammar checker detects four categories of issues: grammar (subject-verb agreement, tense, word usage), spelling (typos and misspellings), punctuation (commas, periods, double spaces), and style (wordiness, redundancy, passive voice).
Whether you are writing a blog post, academic paper, business email, or social media update, grammar checking should be the final step before publishing. Use it alongside our Readability Score tool to ensure your writing is both correct and easy to understand, or check your text length with the Character Counter if you have platform limits.
Grammar quality directly impacts how readers and search engines perceive your content. Studies show that websites with grammar errors have higher bounce rates and lower trust scores. Google has stated that content quality is a ranking factor, and poor grammar signals low-quality content. For content marketers, every grammar mistake is a potential lost conversion. After fixing grammar, optimize your content further with our Keyword Density Checker and Meta Tag Generator.
Our grammar checker detects four types of errors: Grammar (subject-verb agreement, tense issues), Spelling (common misspellings), Punctuation (missing commas, incorrect periods), and Style (redundant phrases, wordiness). Each issue is color-coded for easy identification.

Grammar suggestions flag clear errors (wrong word, missing punctuation). Style suggestions highlight choices that aren't wrong but could be improved - like 'very unique' (redundant) or 'in order to' (could be simplified to 'to'). Style suggestions are optional to accept.
