AI or Not

AI or Not is an iOS app that detects AI-written text using a model embedded on the device. Nothing is uploaded, no account is needed, and checks work offline after a one-time activation. A free tier is capped daily, and Pro is a one-time purchase.

AI or Not is an iOS app from AIorNot, Inc. that checks whether a piece of text was likely written by an AI system. Its defining trait is where the work happens: the detection model is embedded in the app and runs on the phone itself, so pasted text is not uploaded to a server, and the app makes no network calls to the publisher's servers. The tool suits people who want a quick authenticity check but are wary of handing drafts, student work or client copy to a third-party service. Teachers, editors, hiring managers and writers who handle sensitive material are the obvious audience. Because no account is required or offered, there is no sign-up step: a user installs the app, pastes text and reads the resulting score. In practice, the app analyzes pasted text and returns a score, then keeps the text, score and date in a local check history on the device. That history can be deleted inside the app, and removing the app clears its local data. The free tier limits how many checks can be run each day, tracked by a local counter, while a one-time Pro in-app purchase, handled through the user's Apple Account, lifts that limit. The first launch needs an internet connection once, because iOS fetches a decryption key for the encrypted model from Apple. After that activation, detection works fully offline. Among alternatives, most AI text detectors are web services that require pasting content into a browser and often involve accounts, subscriptions or stored submissions. AI or Not trades that server-side approach for privacy and offline use, with the caveat that this listing covers the iPhone app only. Website and API use fall under a separate aiornot.com policy, and details such as model accuracy, supported languages and the Pro price are not described in the source material.
