About

Leon is a personal AI assistant you run on your own machine or server. It can handle a request through fixed native skills or through an agent mode that plans step by step, and it can use tools including desktop and browser control. It keeps layered memory of preferences and recent context, and works with both local and remote AI providers. Speech input and output are supported through several cloud and offline engines. The current 2.0 work is a developer preview.

Use cases: personal-assistant, workflow-automation, browser-automation, agent-memory
