Frequently Asked Questions

Is this grammar checker free?

Yes, 100% free. No account, no credits, no subscription needed.

Basic spell-check only catches misspelled words. AI understands context, so it catches grammatical errors, wrong word usage, and awkward phrasing that spell-checkers miss entirely.

Can I use it for professional documents?

Absolutely. It works great for emails, reports, cover letters, essays, and any professional writing. Always do a final human review for critical documents.

Does it work for non-native English speakers?

Yes. It is especially useful for ESL writers because it explains each correction so you can learn from the feedback.

Is my text stored or shared?

No. Text is processed in real-time and immediately discarded. Nothing is saved or shared.
