About Bourdon
Bourdon is a recognition-first AI memory runtime with a federated agentic memory shared across AI agents. Recognition first. Hydration second. Archive descent third. Bourdon works the way human memory does: it recognizes you instantly, starts responding, and pulls the details up in the background. Claude, Codex, Cursor, Copilot, and Devin write to and read from one shared, federated memory, so a fact learned by one is recognized by the rest, across accounts and machines.
