Check the origin of images and text
This site searches a file or a text for markers that are set when content is generated by a machine. It does not judge how something looks or reads; it reads out what is actually present in the data.
This result is not proof and would not hold up in court. It is not a basis for an accusation against any person. The absence of markers is the normal case and establishes nothing.
Method and limits
| C2PA provenance record | Does the file carry a cryptographically signed provenance record, and does the signature check out? |
|---|---|
| IPTC and EXIF labelling | Do the metadata state the kind of source? |
| Generator working data in the image | Does the PNG file contain the working data of an image generator? |
| Invisible watermark in the image | Can the watermark of the Stable Diffusion reference implementation be decoded? |
| Green/red list watermark | Do strikingly many words fall on their green list? |
| Hidden characters | Does the text contain characters that do not appear when read? |
