## Introduction
NextChat (formerly ChatGPT-Next-Web) is a cross-platform AI chat client that connects to OpenAI, Azure OpenAI, Claude, Gemini, and other LLM providers through a single polished interface. It deploys in one click on Vercel or Docker and runs on web, desktop, iOS, and Android.

## What NextChat Does
- Provides a clean chat UI with markdown rendering and streaming responses
- Supports multiple LLM providers including OpenAI, Anthropic Claude, Google Gemini, and local models
- Offers cross-platform native apps for Windows, macOS, Linux, iOS, and Android
- Manages conversation history, prompt templates, and model parameter tuning
- Enables one-click self-hosted deployment via Vercel, Docker, or static export

## Architecture Overview
NextChat is built with Next.js and TypeScript. The frontend communicates with LLM provider APIs directly from the client or through a lightweight proxy layer. Desktop builds use Tauri for minimal resource consumption. The app stores conversations in IndexedDB on the client side, keeping all data local by default.

## Self-Hosting & Configuration
- Deploy to Vercel with a single click using the repository template
- Run via Docker with environment variables for API keys and base URLs
- Configure model providers by setting OPENAI_API_KEY, AZURE_URL, GOOGLE_API_KEY, or ANTHROPIC_API_KEY
- Set ACCESS_CODE to password-protect your deployment
- Customize system prompts, model defaults, and UI theme through the settings panel

## Key Features
- Multi-provider support: switch between OpenAI, Claude, Gemini, and more in one interface
- Cross-platform native apps built with Tauri for small binary size
- Client-side data storage keeps conversations private by default
- Prompt library with community-shared templates
- Conversation export and import in markdown and JSON formats

## FAQ
**Q: Which AI providers does NextChat support?**
A: OpenAI, Azure OpenAI, Anthropic Claude, Google Gemini, and any OpenAI-compatible API endpoint.

**Q: Is my data stored on a server?**
A: No. Conversations are stored in your browser's IndexedDB by default. No server-side database is required.

**Q: Can I run NextChat fully offline?**
A: The UI can be self-hosted, but it requires network access to reach the LLM provider APIs unless you point it at a local model server.

**Q: How do I update a Docker deployment?**
A: Pull the latest image with docker pull and restart the container. Configuration persists through environment variables.
