As a docs writer, and someone who loves to experiment with code from time to time, I wanted to find out if I could create an application that uses a real documentation set and provides answers based on it. It extends a JavaFX example application I created for the LangChain4j examples repository. At the start, it loads a JSON dataset containing the Azul documentation. When asking questions, the application is able to give correct answers based on this documentation.
