Wrap your model in proof.
Wrap any model -- even your best closed one -- in a provable, reversible, signed layer. Sell trust over commodity quality. Obsign is the proof layer for the AI economy: it proves what your system did, it is not another detector that guesses.
Bring any model
Bit-exact when the model allows it, and an honest guarantee that degrades gracefully when it does not -- the receipt always states exactly which tier it earned. The guarantee never silently overclaims.
Reversible + signed
Every output carries an Ed25519-signed receipt; the original is recoverable and every changed pixel is accounted for. Wrap a closed model and still ship something auditable.
C2PA + trust list
C2PA-aligned receipt export and a published issuer trust list, so a downstream verifier can read your output as trusted -- the rail the content economy is standardizing on.
Read the receipt format
See the canonical receipt format and verify one in your browser -- the exact thing your platform would emit and your users would check.
Detection guesses; provenance proves. Obsign makes the operation re-runnable -- positioning, not a dismissal of detection. AI labs need SDK maturity, trust-list integration, and proof at scale; that is exactly what a design-partner pilot is for.
Build it with us
We take a small number of design partners. A 30-minute call, a use-case review, SDK access, and a pilot with honest commercial terms if it's a fit.
