Olivia is an open-source chatbot written in Go (a programming language developed by Google) that uses a neural network to understand and respond to messages. The goal is to offer a free, self-hostable alternative to commercial chatbot services like DialogFlow. You can talk to Olivia by typing or by speaking, and she can respond with a text message or a synthesized voice. Setting up Olivia involves pulling a Docker container from GitHub Packages and starting it with a single command. Docker is a tool that packages software so it runs consistently on any computer. If you prefer not to use Docker, you can clone the source code directly and run it with the Go programming language installed. A docker-compose file is also provided to start both the frontend chat interface and the backend server together in one step. The chatbot is trained using a JSON file that stores the neural network's saved state. A pre-trained version ships with the repository so it works right away without any extra setup. If you want to teach Olivia new patterns, you can delete that file and retrain the model by restarting the application. Olivia supports conversations in English, Spanish, Catalan, French, German, and Italian, with Brazilian Portuguese partially done. Language coverage details and instructions for adding new languages are in the project documentation. The frontend is a Progressive Web Application, which means it can be installed on a phone and behaves like a native app. This is a community project that welcomes code and financial contributions. Automated checks run on every update to verify code coverage, Docker builds, and formatting.
