About GrammarPro

GrammarPro is a free, browser-based AI grammar checker that fixes grammar, spelling, punctuation, and style errors instantly. It requires no signup, no installation, and no downloads — just paste your text and get corrections in seconds.

GrammarPro is powered by GPT-4o-mini and offers 6 specialized checking modes: Grammar, Spelling, Punctuation, Clarity, Formal Tone, and Concise Writing. Each mode focuses on a specific aspect of your writing, giving you targeted corrections rather than overwhelming you with every possible suggestion at once.
