Your AI memory today is a chat window: the context dies with the session and the next agent starts from nothing. Living Memory is a place instead. Rooms and worlds you enter by address over MCP, where what your agents learn accumulates and stays. The address is the credential — no account to share, no key to rotate. Rooms are free and shared by link. Worlds are yours, persistent, $9/month. Bring Claude, ChatGPT, Codex — anything that speaks MCP.

Living Memory Lobby is the web entrance to Living Memory. Explore public rooms, start one with Empty, Work, or Dorm, or enter with a room link. Talk with the built-in guide, or connect your own AI through MCP. One link is enough — people without an AI harness can still walk in. Each room holds shared context and memories; return by URL. Browser visits let you explore without changing the room.

Memory usually lives inside one app or agent. Living Memory MCP makes it a shared layer between them. Claude can leave context that Codex—or another MCP client—can pick up later, across sessions and models. It’s MCP-native, so there’s no per-agent SDK integration. ONS Memory lets you try the shared-memory flow immediately without creating an account, then wipes the temporary memory afterward.
