# Next.js AI Chatbot

A Next.js 13 and App Router-ready AI chatbot template featuring:

- [Next.js](https://nextjs.org) App Router
- React Server Components (RSCs), Suspense, and Server Actions
- [Vercel AI SDK](https://sdk.vercel.ai/docs) for streaming chat UI
- Support for OpenAI (default), Anthropic, HuggingFace, or custom AI chat models and/or LangChain
- Edge runtime-ready
- [Shadcn UI](https://ui.shadcn.com)
  - Styling with [Tailwind CSS](https://tailwindcss.com)
  - [Radix UI](https://radix-ui.com) for headless component primitives
- Chat History, rate limiting, and session storage with [Vercel KV](https://vercel.com/storage/kv)
- [Next Auth](https://github.com/nextauthjs/next-auth) for authentication

## Model Providers

This template ships with OpenAI `gpt-3.5-turbo` as the default. However, thanks to the [Vercel AI SDK](https://sdk.vercel.ai/docs), switching LLM providers to [Anthropic](https://anthropic.com), [HuggingFace](https://huggingface.co), or using [LangChain](https://js.langchain.com) with just a few lines of code.

## Running locally

You will need to use the environment variables [defined in `.env.example`](.env.example) to run Next.js AI Chatbot. It's recommended you use [Vercel Environment Variables](https://vercel.com/docs/concepts/projects/environment-variables) for this, but a `.env` file is all that is necessary.

> Note: You should not commit your `.env` file or it will expose secrets that will allow others to control access to your various OpenAI and authentication provider accounts.

1. Install Vercel CLI: `npm i -g vercel`
2. Link local instance with Vercel and GitHub accounts (creates `.vercel` directory): `vercel link`
3. Download your environment variables: `vercel env pull`

```bash
pnpm install
pnpm dev
```

Your app should now be running on [localhost:3000](http://localhost:3000/).
