## What it is
A Next.js frontend for the LangChain Chat chatbot, which answers questions about LangChain documentation with cited sources. It provides the chat UI and API routes that connect to a LangChain-powered backend.

## Use cases
- build a chat interface for a langchain rag backend
- add a chatgpt-style ui to my llm app
- frontend for a documentation question-answering bot
- nextjs chat app with openai streaming
- customize a chatbot web ui for my own docs

## When to choose
- you already have a LangChain backend (like chat-langchain) and need a polished chat frontend
- you want a simple, hackable Next.js chat UI to adapt for your own RAG app

## When to avoid
- you need a full chatbot backend - this repo is frontend only
- you need actively maintained, up-to-date dependencies (last release March 2023)
- you want a non-Next.js stack
