About Proof

Proof analyzes whether an image appears to be an unmodified camera original or shows signs of alteration, generation, or reprocessing. Every photo taken by a real camera leaves behind physics-level signals in its pixels. Sensor noise, demosaic patterns, lens artifacts, compression structure. These signals are extremely difficult to replicate.

We extract and analyze these camera pipeline signals across five independent detectors: AI-Generated, Photo-of-Photo, Screenshot, Web-Download, and Camera-Origin. Each detector weighs the signals that matter most for that specific image and shows exactly which signals influenced its answer.

No neural network guessing. No black box. Proof reads the physics baked into every image at the moment of capture and tells you what it found.
