About Grammar Checker
Grammar Checker is a free online writing-checking tool. Paste text from an email, paper, article, message, or social media post to view suggestions about grammar, spelling, punctuation, and clarity of expression in one place, then accept one by one the edits that preserve the original meaning. AI suggestions flag issues at the full-sentence level, helping you complete a quick review before publishing, submitting, or sending, and can also analyze whether the text may be judged to be AI-generated. The tool runs directly in the browser, requires no account registration before checking drafts, and suits quick checks of a passage when switching between shared devices or multiple tabs.
