Check and improve your essay

Five things at once: passages that match published web sources, grammar and punctuation errors, spelling slips, citations that are missing or malformed, and passages that read as model-generated, reported as a likelihood in honest bands. The major checks also have their own pages, under Product in the menu, if you only care about one.

Yes. A free scan needs no account and shows the full report on the first part of your paper: every matched source, every finding, and fixes that work on the spot. A free account saves the report, no card needed. Creating an account does not add another free check. A subscription is for longer papers and every draft you write.

Paste or type anything, or drop a Word (.docx), PDF, .txt, .md or .html file straight onto the card; it is read when you scan. In your account, the editor also takes spreadsheets, images and source code, up to 25 MB.

Published pages on the open web, including journal and publisher pages that are openly reachable. Every match links to its source so you can verify it yourself.

We support English, Spanish, French, German, Portuguese, Italian, Dutch. Documents mixing these languages are checked sentence by sentence. Other languages written with spaces between words may work, but results can be less reliable. Languages written without spaces between words, such as Chinese, Japanese and Thai, aren't supported yet.

Your text is saved in your report so you can come back to it, until you delete the report or your account. A free scan without an account is deleted after about three days. It is never added to an archive other papers are checked against, never shared with your school, never published or resold, and we never use it to train AI models. We configure the providers that process it not to train on it wherever they offer that control; the Privacy Policy names them.
