JPEG forensics

Was this JPEG touched by AI?

Headers, grain, and a trained look at the pixels. A reading — not a verdict you could take to court.

Headers

EXIF, XMP, C2PA, IPTC source type. The loudest tell — when it survives the upload.

Grain

Error-level analysis and residual noise. Generators paint; sensors grit.

Eye

Grok looks at the still for plastic skin, melted type, and impossible light.
