Check a photo for signs of AI generation

No tool can reliably detect every AI image, and you should distrust any that claims to. What you can do is check the evidence a file actually carries: many generators embed signed C2PA Content Credentials asserting AI involvement, some add detectable watermark signals, and metadata often holds hints — a generator's software tag, or the complete absence of camera fields. MetaMarshal reads all of that on your device so you can verify what's checkable and disclose honestly.

Processed on your device — nothing is uploaded unless you tap the optional AI estimate.
Nothing leaves your device to clean a photo — the only exception is the optional AI location estimate, which sends a downscaled copy off-device, and only after you tap to confirm.

How it works

1
Drop the image above; the byte-level scan runs locally and looks for provenance signals.
2
See whether a C2PA manifest is present and what it asserts — including any AI-generation claim signed by the tool that made it.
3
Review watermark signals and metadata hints: generation software tags, missing capture fields, timestamps that don't fit a camera.
4
Weigh the evidence honestly — positive signals are meaningful, but a clean result is inconclusive, not a verdict of 'real'.

Frequently asked questions

No — and nothing can. It reports the signals the file carries: C2PA credentials, watermark indicators and metadata hints. An image that was screenshotted, re-saved or made by a tool that embeds nothing will show no signals, and that absence proves nothing either way.
