A simple, privacy-focused browser extension to export AI chats from ChatGPT, Claude, Gemini, Qwen, Perplexity, DeepSeek, and Meta AI to Markdown or JSON.

This extension was developed for personal use and is not very polished. Additionally, formatting of exported items from certain chats is currently not working well.

• Privacy First: All processing happens locally in your browser. No data is sent to external servers.
• Multi-Platform Support: Works with all major AI chat platforms
  • ChatGPT (chatgpt.com)
  • Claude (claude.ai)
  • Gemini (gemini.google.com)
  • Qwen (qwen.ai, chat.qwen.ai)
  • Perplexity (perplexity.ai)
  • DeepSeek (chat.deepseek.com)
  • Meta AI (meta.ai)
• Clean Markdown Export: Properly formatted with code blocks, tables, and attachments preserved
• Schema-Based JSON Export: Normalized JSON exports for predictable downstream use
• One-Click Export: Simple popup interface for quick exports
