AI Detector Tools for Images, Metadata, and Text
The browser tools are free. They run on Numen's private Mac server and delete each check after processing. The iPhone and Mac apps do the same work on-device. Use the general checker if you are not sure where to start. For a narrower check, pick ChatGPT, Gemini, Flux, Stable Diffusion, SynthID, C2PA, IPTC, deepfakes, or AI text.
