# Open in Chat

The "Open in Chat" feature enables users to seamlessly transfer documentation context to their preferred AI assistant. With a single click, users can open the current page in external AI chat platforms like ChatGPT, Claude, v0, Cursor, and more.

  Help me test Open in Chat for this Geistdocs site. Verify that page URLs resolve correctly, markdown endpoints work, and each configured AI platform receives useful context.

## How it works

On every documentation page, users will find an "Open in chat" button in the table of contents sidebar. When clicked, a menu appears with options to open the page in various AI platforms:

1. User clicks "Open in chat"
2. A dropdown menu shows available platforms
3. User selects their preferred AI assistant
4. The platform opens with a pre-filled prompt containing the page URL and context

The prompt automatically includes:

```
Read this page, I want to ask questions about it. [URL]
```

This allows the AI assistant to fetch and understand the page content before answering user questions.

## Supported Platforms

The feature integrates with multiple popular AI platforms:

### Code & Development Tools

- **[Cursor](https://cursor.sh/)** - AI-powered code editor
- **[v0](https://v0.dev/)** - Vercel's AI interface design tool

### General AI Assistants

- **[ChatGPT](https://chat.openai.com/)** - OpenAI's conversational AI
- **[Claude](https://claude.ai/)** - Anthropic's AI assistant
- **[T3](https://t3.gg/)** - T3 Stack AI assistant
- **[Scira](https://scira.app/)** - AI-powered documentation assistant

## Configuration

The environment variable `NEXT_PUBLIC_VERCEL_PROJECT_PRODUCTION_URL` must be set, which you can read more about in the [Environment Variables](/docs/env) section.

## User Experience

### Desktop Experience

The "Open in chat" button appears in the table of contents sidebar with an external link icon. Clicking it reveals a dropdown menu with all available platforms.

### Platform-Specific Behavior

Each platform has its own integration:

- **Browser-based platforms** (ChatGPT, Claude, v0): Open in a new browser tab with the prompt pre-filled
- **Desktop applications** (Cursor): Open using a custom URL scheme that launches the application
- **Specialized tools** (T3, Scira): Open with platform-specific parameters and context

## Outcomes

### For Users

1. **Context transfer**: Users do not need to manually copy URLs or switch contexts.
2. **Consistent starting point**: Each AI platform receives the same page context.
3. **Tool choice**: Users can open the AI platform they prefer.

### For Documentation Authors

1. **More support paths**: Users can ask follow-up questions about a page.
2. **Lower support load**: AI assistants can answer common documentation questions.
3. **Platform flexibility**: Teams can support different AI preferences.
