Prove it's real.
AI can generate images, video, and audio indistinguishable from reality. Detection algorithms are losing the arms race—they improve, but generative models improve faster. The solution isn't detecting fakes. It's proving authenticity at the source.
Content provenance signs media at the moment of capture—before any opportunity for manipulation exists. Authenticity is proven cryptographically, not guessed by algorithms that can be fooled.
Detection is losing.
Every AI detector can be fooled by the next generation of generative models. False positives destroy trust in legitimate content. The fundamental approach is broken.
- Indistinguishable — AI content is already impossible to reliably detect
- High false positives — Detection models routinely flag authentic content
- Arms race — Every detector is obsolete before it ships
- Eroding trust — All media is now suspect
Provenance wins.
Sign at Capture
Content is cryptographically signed the moment it's created—before any opportunity for manipulation exists.
Anchor to Blockchain
The signature and content hash are recorded on an immutable ledger with a provable timestamp.
Track Chain of Custody
Every edit, transfer, and transformation is recorded, creating verifiable provenance from source to consumer.
Verify Anywhere
Anyone can check authenticity against the blockchain record—no AI detector required, no false positives.

Built on open standards.
Our approach aligns with the Content Authenticity Initiative (C2PA) standards developed by Adobe, Microsoft, Intel, and others. We build on blockchain infrastructure to provide decentralized, permissionless verification that doesn't depend on any single authority.
