About

Leon is an open source personal assistant you can self-host on your own server, designed to act like a virtual brain that does things when you ask it to by leveraging AI concepts such as natural language processing, speech-to-text, and text-to-speech. It lets you interact via text or voice and can even operate offline to keep your data private and under your control, since Leon runs where you choose rather than in the cloud. Built with a modular, skills-based architecture on Node.js and Python, Leon gives users the flexibility to create, install, and share custom modules to extend its functionality for a wide range of tasks and workflows. There’s no hard limit on what you can automate beyond your own imagination. Its modular structure lets contributors and developers build and integrate new capabilities easily, encouraging community growth and customization.

About
