New to content provenance?
Content provenance is cryptographic proof that you created your content. When AI companies scrape the web for training data, they currently can't tell who owns what. Our technology embeds invisible, tamper-proof signatures directly into your text that:
- Survive copy-paste — Your proof travels with your content
- Enable licensing — AI companies can identify and pay you
- Are invisible — Readers see nothing different
Built on C2PA, the same standard used by NYT, BBC, Adobe, and Google. We co-authored the text specification.
