About Leon

Leon is an open-source personal assistant that runs on your own server and performs tasks when you ask, using natural language processing, text-to-speech, and speech-to-text. Its modular architecture lets you install or build packages for new skills, choose cloud or offline voice services, and keep control of your data by deciding which third parties to use.
