## What it is
NLUX is an open-source React and JavaScript library for building conversational AI chat interfaces powered by large language models. It provides React components and hooks like <AiChat /> with adapters for LangChain, HuggingFace, Vercel AI, and custom backends.

## Use cases
- add an ai chat widget to my react app
- build a chatgpt-style interface in next.js
- connect a chat ui to langchain langserve backend
- stream llm responses with markdown rendering in javascript
- create a conversational assistant with custom personas
- integrate huggingface models into a web chat ui

## When to choose
- you need a polished LLM chat UI in React, Next.js, or vanilla JS with minimal code
- you want ready-made adapters for Vercel AI, LangChain, or HuggingFace
- you need streaming markdown responses, personas, and theming out of the box

## When to avoid
- you need a non-JavaScript or native mobile chat UI
- you require voice chat, file uploads, or full accessibility support that is still on the roadmap
- you need a fully custom chat experience where a component library gets in the way
