About

You can’t tell if content is AI anymore — but you can see who’s willing to stand behind it.

AuthSig lets creators sign what they publish and readers verify who authored it and when.
Once signed, content can’t be secretly changed or disowned.
The proof is public, tamper-resistant, and verifiable — all directly in your browser.
