What Is Grammar Checker?
An AI grammar checker goes beyond basic spellcheck — it understands context, sentence structure, tone, and style. Formly's free grammar checker detects and explains grammatical errors, punctuation mistakes, word choice issues, awkward phrasing, passive voice overuse, run-on sentences, and style inconsistencies. Unlike simple red-underline spell checkers, it provides clear explanations for each correction so you understand why the change improves your writing. Works for emails, essays, blog posts, reports, cover letters, and any professional document.
