Show HN: Pupul, portable and revocable memory you carry into any AI

Pupul launches a portable, revocable memory system that lets users carry personal context into any AI assistant and revoke it instantly with one tap, using offline-verifiable ES256 tokens. The demo shows an assistant adapting to a user's style and then going blind mid-task upon revocation, highlighting user-controlled memory that persists across AI models.

A fresh assistant meets Ava by her consented Pupul, on our best model. It has never met her, yet it already fits. Then she revokes, and the same assistant goes blind mid task. Sixty seconds, live and real. Ava signs in with a genuine ES256 token, verifiable offline against our public JWKS. No callback to us, ever. When she revokes, the signature is still valid. Access dies anyway. That gap is the whole point. The assistant gets her word, her rhythm, and how to meet her. How she folds under pressure never leaves her, at any price. This is the memory the labs will not give you: one you carry into any AI, and take back with one tap. See the button /sign-in-with-pupul . Get your own Pupul /identity
