Bits launches open-source personal agent

Bits makes a compelling case that personal agents should be inspectable, persistent, and model-agnostic rather than trapped in a cloud chat window.

• –Background routines and durable task state let work continue after the app closes or crashes.
• –Plain Markdown memory is transparent, editable, and easier to debug than opaque vector-only storage.
• –Sentinel review and encrypted local secrets address risky actions, though any always-on agent still warrants careful permissions.
• –MCP support and broad model compatibility give developers a practical foundation for extending the agent.
• –The polished cards, voice mode, and quick-ask overlay make a developer-oriented system feel approachable for everyday use.
