Vaadin AI assistant application

AI powered expert system demo

This app shows how you can use LangChain4j to build an AI-powered system that:

• Has access to terms and conditions (retrieval augmented generation, RAG)
• Can access tools (Java methods) to perform actions
• Uses an LLM to interact with the user

All credit for the example goes to LangChain4j, this demo simply expands on it by adding a React UI and a database.

Requirements

• Java 17+
• OpenAI API key in OPENAI_API_KEY environment variable. Create your API key here: platform.openai.com/api-keys

Running

Run the app by running Application.java in your IDE or mvn in the command line.
