Leon: Your Open-Source Personal AI Assistant — Complete Guide
Meet Leon, the open-source personal AI assistant that runs on your own server. Voice and text interaction, extensible skills, and full data privacy — explained in depth.
What Is Leon?
Leon is an open-source personal AI assistant that lives entirely on your own server. Unlike cloud assistants that send your data to third parties, Leon runs locally, communicates via voice and text, and understands you in multiple languages. It was created with a simple mission: give everyone a private, extensible assistant they actually own.
