Artificial Intelligence

Building a custom AI chatbot with Spring Boot, React, and LangChain4j

Have you ever wanted to build an intelligent chatbot that understands your specific business context? This presentation takes a practical engineering approach to AI. You'll learn how to interact with large language models (LLMs) from code and how you can extend their capabilities by giving them access to your own content and selected Java methods. This talk will feature hands-on coding, where you'll learn to implement a custom AI chatbot with Spring Boot, React, LangChain4j, and Hilla. Walk away with a solid understanding of how you can integrate AI into your own application.
