Talk to Your Documents with LangChain and JavaScript

This intermediate course path teaches you how to create chat applications that answer questions using information from your own documents. You will work with LangChain in JavaScript to connect conversational interfaces with document processing and retrieval workflows. You will learn how to load, split, embed, and search document content so an AI application can find relevant source material. The path also covers conversational memory and response customization, helping you build chat experiences that maintain context across exchanges. By the end, you will be prepared to build retrieval-augmented generation applications for use cases such as document analysis, knowledge-base chat, and information retrieval from private document collections.
