Your writing

The quick check runs in your browser and sends nothing. The deeper checks send your text to GPT Nada's own private computer, which runs the models itself. Your text waits there only while a check is queued or running, and is wiped as soon as the result is ready. It is never used to train anything and is never shared.

Searches that leave Nada

• Sources sends short phrases from your essay (about nine words each) to Brave Search.
• Citations sends the titles of your references, and one author's surname, to Crossref, OpenAlex and Open Library.

Nothing else from your essay leaves the Nada computer.

What we keep

• A random code in your browser, so we can count how many different people use the site. It holds no name, no email and no text. Clearing your browser's site data removes it.
• For each check, the time, the kind of check and that random code. Never the text.
• Your network address, held for up to 10 minutes, only to stop one person flooding the queue.
• If you press Report a problem, we keep your note for 30 days, then delete it. If you tick the box, your text and the results on screen (the same as Download report) are sent too. They move from the website to the GPT Nada computer within a day, and are deleted there once the problem is sorted.
• If you pick light or dark, that choice lasts only until you close the tab.

Other companies your browser contacts

Fonts and logo artwork are served by this site. Opening a Word file, PDF or picture loads a reader from jsDelivr, and the reading itself happens in your browser. Pages are served by Cloudflare. Cloudflare Web Analytics counts visits to each page without cookies and filters out known bots, so we can see roughly how many visits the site gets; it does not identify you and never sees your text. Before a check runs, Cloudflare Turnstile confirms that a real browser is asking, usually without you seeing anything; it does not see your text. No advertising or cross-site tracking services are used.

What the results mean

Results are estimates from writing patterns. They are not proof that anyone used or did not use a machine, and should never be used on their own to accuse someone.
