How to build smarter frontend chatbots with RAG and LangChain.js

Chatbots can now understand user context by combining retrieval-augmented generation (RAG) with LangChain.js. This approach allows bots to deliver personalized responses based on where users are in an app, their subscription plan, and recent activities. RAG works by retrieving relevant information from your knowledge base and generating tailored responses, creating a more helpful assistant that adapts to users rather than forcing them to adapt to generic answers.
