What does Actx0 do?

Actx0 is a managed memory infrastructure designed specifically for AI agents and applications. Instead of replaying full chat transcripts every time an agent needs context, Actx0 stores session memories and workspace knowledge, then returns only the relevant pieces in under 10 milliseconds. It sits between your model and your user, handling the storage and retrieval so your agent can pick up where it left off without carrying the whole history.
