0byte gives every AI generation a fingerprint and a public proof of origin — who made it, with which model, and when. Anyone can check it, even from a screenshot.
They attach trust to the file. The internet strips the file.
Labels like C2PA get stripped the moment you upload to any platform. Watermarks only cover one vendor’s models and fade under screenshots and re-encoding. Standalone detectors hand you a probability with no evidence behind it.
None of them hold up where it matters — in a newsroom, or a courtroom.
The proof has to live outside the file, based on what the content looks like. That’s 0byte.
Proof of origin that lives outside the file — verifiable by anyone, with detection as the safety net.
0byte reads what the content looks like and turns it into a fingerprint. Screenshots, trimmed edges, color shifts, and re-uploads still match — and your image stays byte-for-byte identical.
Every generation gets a digitally signed proof in an append-only public registry — who made it, with which model, and when. The same structure that secures HTTPS, so no one can quietly rewrite it.
If content was never stamped, you still get an answer — an AI-detection score, clearly marked as a statistical estimate, not proof. The registry only gets stronger as more platforms stamp.
C2PA and watermarks each solve part of the problem. 0byte is built for the part of the journey where they break — and surfaces their signals too when they survive.
Signed metadata attached inside the file — stripped the moment a platform re-encodes it on upload.
Embedded pixels that only cover one vendor’s own models — and fade with screenshots and re-uploads.
Proof lives in a public registry, not the file — so it survives stripping and re-encoding. And when a label or watermark does survive, verification surfaces it too. One call, every signal.
Stamping takes under 50ms and runs in the background. Verifying is free and needs no account.
Add 0byte to your pipeline in a single line. Stamping takes under 50ms and runs in the background — your users never feel it.
The fingerprint and a signed proof go into an append-only transparency log that only grows — auditable by anyone, rewritable by no one.
Send any content to one endpoint and get the origin back — provider, model, timestamp, signature. Free, and no account required.
No registry match? You still get a verdict — an AI-detection score, returned as a calibrated estimate rather than proof.

}Only the fingerprint and proof metadata — never the image itself. The fingerprint can't be reversed back into your image.
Ever. They never touch our systems, and neither does any personal data.
No metadata injection, no watermarks. The image you ship is byte-for-byte identical to the one you made.
Verifying is free with no account. Detection works without stamping, and stamping works without anyone verifying.
byteEverything that passes through carries a signed proof of origin — provable anywhere it travels.
