Leon is an open-source personal assistant designed to run on your own server and help you automate tasks through a modular “skills” system. It supports both text and voice interaction, with optional offline operation to keep data under your control.

Key Features

  • Modular skills architecture to add and share new capabilities
  • Text-based assistant via a web interface
  • Voice assistant capabilities with speech-to-text and text-to-speech (cloud or offline options)
  • Local/offline mode to reduce reliance on third-party services
  • CLI-based installation and management
  • Hybrid stack with a Node.js core and Python integration for certain NLP/skill components

Use Cases

  • Personal workflow automation (recurring tasks, quick actions, utility commands)
  • Building and sharing custom assistant skills for a household or team
  • Privacy-conscious local assistant for text/voice interactions

Limitations and Considerations

  • The project is undergoing a major architectural rewrite; the develop branch may be unstable and documentation may lag behind implementation

Leon is a good fit for users who want a customizable, privacy-oriented assistant they can extend with their own skills. Its modular design makes it suitable as a long-term personal automation hub as capabilities evolve.

Willow

Willow

Self-hosted voice assistant platform for ESP32 devices with on-device wake-word and command recognition, Home Assistant integration, and an optional inference server for STT/TTS/LLM.

Willow is an open-source, privacy-focused voice assistant platform designed for low-cost ESP32-S3 hardware. It provides fast on-device wake-word and command recognition and can optionally integrate with a self-hosted inference server for high-quality speech-to-text, TTS, and LLM tasks. (heywillow.io)

Key Features

  • On-device wake-word engine and voice-activity detection with configurable wake words and up to hundreds of on-device commands. (heywillow.io)
  • Integration with Home Assistant, openHAB and generic REST endpoints for home automation and custom workflows. (heywillow.io)
  • Willow Inference Server (WIS) option: a performance-optimized server that supports ASR/STT (Whisper models), TTS, and optional LLM inference with REST, WebRTC and WebSocket transports. WIS targets CUDA GPUs for low-latency workloads and includes deployment scripts and Docker compose support. (github.com)
  • Device management and OTA flashing via the Willow Application Server (WAS) with a provided Docker image to simplify onboarding. (heywillow.io)

Use Cases

  • Privacy-first smart-home voice control: local wake-word and command recognition that triggers Home Assistant automations without cloud transcription.
  • On-premises speech processing: self-hosted WIS for low-latency ASR/STT and TTS for accessibility, transcription, or edge assistant applications.
  • Developer integrations: embed Willow devices into custom REST/WebRTC workflows or use WIS to add LLM-powered assistants to local networks. (github.com)

Limitations and Considerations

  • Advanced WIS features (LLM, high-quality TTS) expect CUDA-capable GPUs and NVIDIA drivers; CPU-only setups are supported but significantly slower and may disable some features. (github.com)
  • Primary device target is the ESP32-S3-BOX family; other hardware may require additional porting or tuning. (heywillow.io)

Willow combines a small-footprint device runtime with an optional, high-performance inference server to enable private, low-latency voice assistants and on-premises speech workflows. It is actively developed with documentation, Docker deployment options, and community discussion channels for support. (heywillow.io)
