Notary

Proves the conversation really happened with the AI, not typed up afterward.

Asleep · coming later

Clerk

Dami keeps each author's public board and openness score, so nobody can lock twenty versions and show only the best one.

How it works

Export your chat from Claude or ChatGPT.
Lock it. Hide what's private. Paste the code it gives you at the end of your piece.
Date it. One click, free.
Post it. Readers check it against your code.

It runs in your browser. No account, no upload, nothing to install.

What a check tells you, honestly

It does show the conversation is exactly what the author locked, and, if dated, the day it existed by.
It doesn't show yet that the conversation really happened with an AI (that's the Notary), or that the author locked only one version (that's the Clerk). Hidden parts are marked so you can ask about them.
