The short answer
Leon (17,401 stars, MIT) is the leading open-source personal assistant in 2026: a self-hosted, privacy-first assistant that you can run on a laptop, VPS, or Raspberry Pi. It supports skills, speech, and now LLM integration - making it the closest thing to a local Jarvis that actually works.
What Leon does
- Skills architecture: modular skills (weather, news, reminders, web search, calculations, and more) you can install or write yourself.
- Speech interface: wake word + speech-to-text + text-to-speech pipeline (works with Whisper and Piper).
- LLM-powered: connect it to a local or cloud LLM for open-ended conversation and task handling beyond fixed skills.
- Self-hosted: runs via Docker; your data stays on your machine.
git clone https://github.com/leon-ai/leon
cd leon
./scripts/install.sh
./scripts/run.sh
# then interact via web UI, CLI, or voice
2026 use cases
- Private voice assistant: home automation commands without cloud voice processing.
- Personal automation hub: chain skills - "summarize today's news and email it to me".
- Development playground: write custom skills in Python/Node and hook LLM calls.

| Cost | Free | Free, but data costs |
FAQ
Is Leon stable enough for daily use? It's community-maintained; expect to tinker. It shines as a learning platform and privacy-first assistant rather than a polished consumer product.
Can it control smart home devices? Yes, via skills and integrations (Home Assistant integration is common - see our Home Assistant LLM guide).
Does it need a GPU? No - works on CPU; LLM features get faster with a GPU or use a cloud API.
