# Leon

An open-source personal AI assistant built around tools, context and memory, able to plan and carry out multi-step tasks locally or with remote AI providers rather than only answering with text.

Leon is an open-source personal AI assistant built around tools, context, memory and agentic execution. It can run in a smart mode that picks its own approach, a controlled mode that follows deterministic native skills and actions, or an agent mode that plans a task step by step.

It supports native skills for controlled actions and SKILL.md-backed agent skills for open-ended workflows, and can use real tools to complete tasks rather than only replying with text. A computer-use capability lets it operate desktop and browser interfaces and verify visual outcomes, running locally or through a companion component. It keeps layered memory covering durable preferences, day-to-day context and recent discussion, and can use both local and remote AI providers.

The project is currently focused on a 2.0 developer preview with agentic execution, while a more stable, pre-agentic release remains available on a separate branch. It is written in TypeScript and Python.
