Invite-only

Arrive with your history.

A private vault. Named grants for Claude, ChatGPT, and Grok. When you switch, they start with you—not a blank thread.

A closed folio on a dark table, ember light at the edge.

New models start cold.

ChatGPT, Claude, Grok—each one asks you to begin again. An export dumped into a prompt is not the same as a life, kept current, with a say in who sees it.

Vault

One place for what you already wrote.

Combine official chat exports, durable agent memory, and standing facts. Newer notes replace older ones. Last-known stays.

Grant

Each model sees only what you opened.

Parent inherits. A child can revoke. Secrets stay home. A dump is not a grant.

Connect

Claude, ChatGPT, or Grok.

Attach a query grant. The next model walks in warm. You do not re-teach it from scratch.

Two ordered trails of paper memory cards converge into one dark folio with an ember crease.

Already run an agent?

Your agent already knows what the next model doesn’t.

Pack durable memory from Hermes or OpenClaw into the same dated vault as your chat history. Grant the useful parts outward while credentials, raw sessions, databases, media, and tool authority stay local.
