Verify AI-generated content

Everything DSGHT.ai generates is marked as AI-generated in a machine-readable way. Downloads also carry a signed provenance token in the X-AI-Provenance response header. Paste a token, add the file or its text, and this page tells you what it can prove. Files are hashed in your browser and never uploaded.

Provenance check

Files are hashed in your browser and never uploaded.

The file (PDF, DOCX, Markdown, HTML…)

Pasted text rarely matches a signed file byte for byte. For a hash check, use the original file.

How this works

  • A token is an Ed25519 signature over a small record: the SHA-256 of the exact bytes we served, when, and that the content is AI-generated.
  • Our public keys are at /.well-known/dsght-ai-provenance, so you can check a token without this page.
  • Frontmatter, meta tags and document properties are unsigned marks: they say a file was marked, and anyone can add or remove them.
  • Finding no marking does not prove a human wrote something.
