Leon is a framework for building personal AI assistants that integrates large language models with local tool execution and persistent memory. It functions as an agentic workflow orchestrator and modular skill engine, enabling the creation of autonomous assistants capable of planning and executing multi-step tasks.
The system features a retrieval-augmented generation memory architecture that indexes conversation history and user facts for context-aware grounding. It utilizes a modular skill system to interact with external binaries and APIs, supported by a loop that handles tool calling, schema validation, and failure recovery.
The project covers several broad capability areas, including voice interaction through speech-to-text and text-to-speech synthesis, natural language understanding for intent parsing, and a dynamic persona engine that adapts communication tone. It also includes administrative interfaces for assistant information management and security layers for HTTP API and client socket access.
The application is provided as a dockerized AI server to ensure consistent deployment and hosting.
