2. Click the extension icon in your Chrome toolbar
3. Choose your export options:
   - **Include thinking blocks** - Include Claude's extended thinking

## Features

- Exports full conversation including all messages
- Optionally includes Claude's thinking process
- Optionally includes tool usage details
- Three output formats: Markdown, JSON, Plain Text
- Works with your existing claude.ai session (no separate login)
- Shows preview and file size before export

## Troubleshooting

**"Please navigate to a Claude.ai chat first"**
- Make sure you're on a page like `https://claude.ai/chat/xxxx-xxxx-xxxx`

**"Could not determine organization ID"**
- Try refreshing the Claude.ai page and reopening the extension

**"Authentication failed"**
- Your session may have expired. Log into claude.ai again.

## How It Works

The extension uses your existing Claude.ai session cookies to call the same API that the Claude web interface uses. It fetches the full conversation data and formats it into a readable export.
