Does Is This AI upload my files?
No. All models are bundled in the app and run on your phone. No file, scan, or result ever touches a server.
How accurate is it?
Detection results are probabilistic estimates. Accuracy varies with image quality, audio clarity, text length, language, and which AI system generated the content. Always apply independent judgment, results shouldn't be used as sole evidence for high-stakes decisions.
Does it work offline?
Yes. Once installed, the app requires no internet connection to perform scans.
What content can I scan?
Images (JPEG/PNG/HEIC), plain text (pasted or typed), and audio files (common formats). Live microphone recording is not supported.
