👋 Introduction

Leon is an open-source personal assistant who can live on your server.

He does stuff when you ask him for.

You can talk to him and he can talk to you. You can also text him and he can also text you. If you want to, Leon can communicate with you by being offline to protect your privacy.


  1. If you are a developer (or not), you may want to build many things that could help in your daily life. Instead of building a dedicated project for each of those ideas, Leon can help you with his packages/modules (skills) structure.
  2. With this generic structure, everyone can create their own modules and share them with others. Therefore there is only one core (to rule them all).
  3. Leon uses AI concepts, which is cool.
  4. Privacy matters, you can configure Leon to talk with him offline. You can already text with him without any third party services.
  5. Open source is great.

What is this repository for?

This repository contains the following nodes of Leon: - The server - The packages/modules - The web app - The hotword node

What is Leon able to do?

Today, the most interesting part is about his core and the way he can scale up. He is pretty young but can easily scale to have new features (packages/modules). You can find what he is able to do by browsing the packages list.
