AI or Not: Text Detector

AI or Not identifies whether text was written by a person or by an AI model like ChatGPT. Users can paste essays, cover letters, emails, or news articles to receive a probability score, a final verdict, and sentence-level highlights showing exactly where AI was detected. Designed with privacy as a priority, the full detection model lives directly inside the app, ensuring that text is processed locally and never uploaded to a server. The tool also integrates with the system share sheet to analyze text directly from Safari or other applications.
