FAQ

Is AI proofreading as good as a human proofreader?

It is fast and catches most common errors, but it can miss things or suggest a wrong change. For important documents, have a person read the final version.

Can I proofread long documents?

Paste the text in parts. Free checks take up to 500 words at a time; Pro takes up to 5,000.
