PROOF - AI or Not?

PROOF · AI detection made easy

AI Image Detector:
Upload any photo. PROOF runs 80+ physics-based signals (light, sensor noise, lens distortion, compression history) and gives you a verdict in seconds: Original, Unclear, or Modified.

What PROOF detects:
• Camera-origin photos
• AI-generated images
• Edited content

AI or Not? Quiz:
A swipe game that trains your eye to spot AI-generated photos. Easy, Medium, and Hard rounds. Climb the leaderboard. Challenge friends head-to-head.

Why PROOF holds up when a new AI generator launches: Most AI detectors only learn what AI photos look like. They start guessing the second a new generator ships. PROOF learns that signal and the physical fingerprint a real camera leaves on a real photo (light, sensor noise, compression history). That fingerprint is the same across every AI model. The visual style can shift overnight; the camera-origin signal can't.
