Provenance Lens

About Provenance Lens

Who maintains Provenance Lens, why it reports evidence instead of probability, and its independence from the AI providers whose signals it inspects.

Evidence, not guessing

Provenance Lens reports only what can be checked: a cryptographically signed manifest, a metadata field, a specific codepoint, a documented provider mechanism. When a signal cannot be checked, it says so. It never converts silence into a verdict.

Runs in your browser

The check runs in your browser. Your file is not uploaded โ€” it never reaches our servers. You can verify that in your browser's network tab while a scan runs.

What a report cannot prove

  • A valid signature proves who signed a manifest, not that the manifest's claims are true.
  • Metadata is trivially editable. Treat generator fields as an indication, never as proof.
  • Hidden Unicode characters have many innocent causes, including ordinary copy-paste.
