AI Image Check
Read the provenance evidence in an image file — no guessing, no fake percentage.
What this checks, and what it cannot
This reads the evidence inside the file — signed Content Credentials, the standard field generators write to declare themselves, the generator's name, and the prompt block Stable Diffusion saves. All of it is checkable.
It does not look at the picture and guess. Tools that claim to spot AI images from pixels alone are wrong often enough in both directions to ruin someone's reputation, and a screenshot defeats them entirely. HIMEXA will not give you a confidence percentage, because an honest one cannot be produced.
The consequence worth remembering: finding evidence tells you something; finding none tells you nothing. Metadata is stripped by screenshots, re-saves and most social platforms.
Check where an image came from
Works best on the original file. A screenshot of an image has none of the original's metadata.

The file is read in your browser and never uploaded. You can confirm that by opening this page with the network tab open, or by turning off your connection first — it still works.
About this tool
Checks what an image file says about its own origin: signed C2PA Content Credentials, the IPTC field generators use to declare AI output, generator names in the metadata, and the prompt block Stable Diffusion embeds in PNGs. It reports each finding with what it does and does not prove. It will not score an image from its pixels, because no tool can do that reliably.
There is no dependable way to look at an image and tell whether a model made it. The detectors that claim to do this are wrong in both directions often enough to matter — real photographs get flagged, generated images pass — and taking a screenshot defeats them. Publishing a percentage from one of those would be inviting people to accuse each other on the strength of a number that means very little.
What can be checked is what the file says about itself. C2PA Content Credentials are cryptographically signed. The IPTC digital source type is a field generators set on purpose to declare their output. Stable Diffusion writes the prompt, seed and model into the PNG. Those are facts about the file, and this page reports them with what each one does and does not establish.
The asymmetry is the whole point: evidence found is worth something, evidence absent is worth nothing. Most images on the internet have no metadata left at all, because uploading strips it.
