AI Image Evidence Checker

ProvenanceByte markersCamera / Frequency

Works best with original image files. Free AI image evidence checker for original files: review C2PA Content Credentials, OpenAI-style markers, EXIF metadata, byte markers, camera-like evidence, and frequency signals. Screenshots and reposted images may lose provenance metadata, so results are evidence-based—not a definitive verdict.

OpenAI/C2PA marker-only strings can be detected, but this runtime cannot cryptographically verify C2PA manifests.

How the checker works

Check image provenance with evidence, not false certainty.

Our model weighs signals in layers: verified C2PA provenance first, marker-only indicators next, then metadata, byte-level traces, and frequency clues.

FAQ

Common questions about AI image evidence checks

Evidence, not certainty

Can this tool prove whether an image is AI-generated?

No. It reports evidence signals such as C2PA Content Credentials, marker strings, camera-like metadata, and frequency clues. It is an evidence checker, not a definitive AI detector.

Missing is not proof

What does it mean if no C2PA data is found?

No C2PA data means supported provenance metadata was not found. It does not prove that the image is fake or AI-generated because metadata can be absent, stripped, or never added.

Original files help

Should I upload a screenshot or the original image?

Upload the original image whenever possible. Screenshots, social reposts, and compressed copies often remove provenance metadata and weaken the evidence report.
