Chat LangChain is a production-ready documentation assistant agent that answers questions about LangChain, LangGraph, and LangSmith, built with Managed Deep Agents and LangGraph. It includes a Python backend agent with documentation search, support KB lookup, link validation, and guardrails, plus a Next.js chat frontend.

Use cases

• build a chatbot that answers questions from documentation
• deploy a production RAG assistant over docs
• learn how to build agents with LangGraph
• add guardrails to keep an LLM chatbot on-topic
• create a support assistant backed by a knowledge base
• self-host a documentation Q&A chat UI

When to choose

• you want a reference implementation of a production RAG/agent chatbot
• you need a docs assistant for LangChain ecosystem tools
• you want to see Managed Deep Agents, MCP connectors, and guardrails in practice

When to avoid

• you need a generic no-code chatbot builder
• your docs are unrelated to LangChain and you want an out-of-the-box solution without customization
• you cannot use external LLM API keys or managed services
