About Leon
Leon is a personal assistant you host yourself. It is built on Node.js and Python, and it does things when you ask. A modular architecture lets you use or write packages of skills to automate everyday tasks.
Leon uses natural language processing, text-to-speech and speech-to-text. For voice you can use cloud services such as Google Cloud, AWS or IBM Watson, or offline engines like CMU Flite. Because it runs on your own server, you decide whether any third party sees your data.
