AI or Not: Text Detector

Did AI write that? Paste any text and get an answer in seconds. All detection runs only on your phone so the content you check will never leave your device.

AI or Not checks if text was written by a person or by AI like ChatGPT.

Paste in an essay, a cover letter, email, news article or any other text. In a few seconds you get a score, a verdict, and highlights where AI was used.

Everything remains on your phone: the app has the full detection model inside it, the same one that powers aiornot.com. Your text is never uploaded anywhere.

PRIVATE BY DESIGN Every check runs on your phone. Yes, the AI model lives in the app.
