What to do insteadInspect the file directly with a metadata and marker viewer

We keep this page narrow on purpose: where a generator has not published a metadata or provenance policy, the honest answer is that we do not know, not a guess dressed up as a fact. xAI has not published documentation comparable to OpenAI's or Adobe's C2PA statements for Grok's image generation feature at the time this page was last checked.

That makes direct inspection more important, not less. Run any file you are evaluating through our metadata viewer and Content Credentials marker inspector and read exactly what fields are present, rather than assuming a policy that has not been documented publicly. If xAI publishes a clear policy, this page will be updated to reflect it.

Questions this page answers

Does an empty metadata result mean the image is not from Grok (xAI)?

No. A missing field can mean the metadata was never written, was stripped by an export or upload step, or was not inspected by this tool. Treat it as inconclusive, not as proof either way.

Does this page verify a specific image is from Grok (xAI)?

No. It describes documented or observed behavior for Grok (xAI) in general. To evaluate one file, inspect it with our metadata viewer and Content Credentials marker inspector and weigh the result alongside other context.
