Frequently asked questions
What is the difference between the three modes?
Fix only corrects grammar, spelling and punctuation without touching your wording. Fix + improve also breaks up run-on sentences and removes awkward phrasing. Make fluent rewrites your text the way a native English speaker would phrase it - ideal for non-native speakers.
Is this grammar checker free?
Yes - completely free with no signup, powered by open-source AI models via OpenRouter. Each user gets 10 corrections per hour so it stays free for everyone.
Does it work for emails and essays?
Yes. It handles anything from a two-line email to an 8,000-character essay, report or cover letter, and keeps your original tone and meaning.
Is my text stored anywhere?
No. Your text is processed to generate the correction and is not saved on our servers.
