How It Works

The extension extracts chat messages directly from the page's DOM structure. Each AI platform uses different HTML structures, so the extension includes platform-specific extractors:

• ChatGPT: Uses data-message-author-role attributes
• Claude: Uses class-based selectors for human/assistant messages
• Gemini: Uses query/response container structure
• Z.AI: Uses user-message and chat-assistant classes
• DeepSeek: Uses ds-markdown for responses with specific user message containers
• Kimi: Uses chat-content-item containers with user/assistant variants
• Qwen: Uses qwen-chat-message containers with role-specific classes

Privacy

• No data collection: All processing happens locally in your browser
• No external servers: Chat content never leaves your device
• No tracking: The extension doesn't collect any analytics

Troubleshooting

"No messages found"

• Make sure you have an active chat conversation open
• Try scrolling through the conversation to load all messages
• Refresh the page and try again

Export button is disabled

• Ensure you're on a supported platform
• Check that the chat has loaded completely

PDF is empty or incomplete

• Some platforms lazy-load messages - scroll through the entire conversation first
• Try disabling the "Include thinking" option if the AI platform doesn't support it
