Leon AI is an open-source, self-hosted virtual assistant designed to offer the convenience of digital helpers without compromising user privacy. Unlike commercial alternatives that trade data for convenience, Leon operates entirely on the user’s own server, granting complete control over data and interactions. Its modular architecture, built with “skills” as self-contained units, allows for scalability and customization, enabling users to add new functionalities without updating the entire system. The MIT license under which it’s released promotes freedom, speed of development, and community contribution, making users part of the tool’s ownership. Leon supports an offline mode, providing digital sovereignty for sensitive data and conversations. Recent development focuses on integrating foundation models in a hybrid approach, balancing the power of large AI brains for complex tasks with faster, lighter methods for basic commands. Users can choose their preferred AI technologies for Natural Language Processing, Text-to-Speech, and Speech-to-Text, with options for both cloud services and robust local alternatives. The project relies heavily on community involvement, with a Discord channel for sharing ideas and contributing code. Financial support through sponsorships is crucial for its sustainability, allowing core contributors to dedicate more time to its development. Installation involves setting up Node.js and NPM, followed by installing the Leon CLI and using commands like “Leon create” and “Leon start” to set up and run the assistant, accessible via a web browser at localhost:1337. Leon AI represents a shift towards demanding higher standards for data privacy and user control in technology.
