Receipts for every
conversation with AI.
Mneme is a browser wallet that signs a cryptographic receipt for any reply from ChatGPT, Claude, or Gemini. The hash is anchored to Ligate Chain. The content stays on your machine.
Three clicks from conversation
to a receipt onchain.
No accounts. No third-party server reading your messages. Mneme signs locally and anchors a hash. The receipt is the only thing that leaves your browser.
Open the conversation.
Continue using ChatGPT, Claude, or Gemini the way you already do. Mneme adds a small Attest button next to every assistant reply, invisible until you want it.
Click Attest.
Mneme captures the model id, prompt hash, and response hash, then asks your wallet to sign. Your keys never leave the device.
Receipt onchain, verifiable forever.
Mneme returns a lat1… receipt. Anyone with the original conversation can verify it. No one without it learns a thing.
A small wallet. Few promises.
All of them mechanical.
A conversation with a model happened. Mneme is the smallest tool that proves it, and the smallest we could ship that nobody, including us, can read.
Works where you already think.
Mneme injects only the Attest button. Nothing in your conversation is altered, captured, or transmitted unless you click it.
Memory you can prove.
Install Mneme, pin it to your toolbar, and your next conversation is the first one you can carry forever.
