Stateful agents with persistent memory that learn continuously rather than resetting each session.
- Stateful agents that persist memory across sessions
- Continuous learning rather than per-session resets
- Memory management beyond the limits of a context window
Directly addresses the memory limit that undermines most agents
Infrastructure rather than a ready-made application

vs Vectorize−0.2
Catches where an enterprise agent failed, routes it to an expert, and keeps the correction.
- Failure detection on deployed agents
- Routing to the specific expert who can validate
- Governed memory built from validated corrections
Closes the correction loop most agent deployments leave open
