AI Chat Exporter

Export your Gemini and ChatGPT conversations to perfectly formatted Markdown files with complete preservation of LaTeX math, code blocks, tables, and all formatting. Version 4.0.0 introduces DOM-based extraction for Gemini—eliminating clipboard dependencies for more reliable, privacy-friendly exports.

Features

• DOM-based extraction for Gemini (v4.0.0+): Direct HTML parsing without clipboard dependency using Turndown library
• Export your full Gemini or ChatGPT chat conversation to Markdown, preserving formatting (code, tables, LaTeX, etc.)
• Dedicated "Export Chat" button appears automatically on every Gemini and ChatGPT chat page
• Option to hide the export button via the extension popup
• Granular message selection: Use checkboxes next to each message to select exactly what to export
• Selection presets: Instantly select all, none, or only AI responses with a dropdown
• Export to clipboard or file: Copy your chat as Markdown directly to your clipboard—no file download needed, or save as .md file
• Custom filename (optional): Enter a filename, or leave blank to use the chat title or a timestamp
• Automatic lazy-loading: Scrolls to load all messages in long conversations before export
• Citation removal: Automatically strips Gemini citation markers from exported content
• Math formula support: Preserves LaTeX equations from Gemini's data-math attributes
• Dark mode support: Export controls display correctly in both light and dark themes
• No build step required
• Open source under the Apache License 2.0

What's New in v4.0.0

🎉 DOM-Based Extraction for Gemini

• No more clipboard dependency: Gemini exports now use direct DOM parsing with the Turndown library
• More reliable: Eliminates clipboard race conditions and retry logic
• Better formatting: Direct HTML-to-Markdown conversion preserves complex formatting
• Math formula support: Extracts LaTeX equations from Gemini's data-math attributes
• Enhanced privacy: Clipboard access no longer required for Gemini

Technical Improvements

• Integrated Turndown.js for robust HTML→Markdown conversion
• Custom Turndown rules for math blocks, inline math, and tables
• Improved citation removal algorithm
• Fallback to manual DOM traversal if Turndown unavailable

Migration Notes

• Old clipboard-based implementation preserved as gemini_old.js
• ChatGPT export unchanged (still uses clipboard method)
• All UI features maintained (checkboxes, selection presets, custom filenames)

Usage

Gemini

1. Go to Gemini and open any chat conversation.
2. Click the Export Chat button at the top right of the page.
3. In the export menu, use the Select messages dropdown to quickly select "All", "Only answers" (AI responses), or "None". You can also manually check/uncheck any message using the checkboxes on the right of each message. If you make a custom selection, the dropdown will show "Custom".
4. Choose your export mode:
   • Export as file (default): Downloads a Markdown (.md) file
   • Export to clipboard: Copies the conversation to your clipboard for pasting elsewhere
5. (Optional) Enter a custom filename, or leave blank to automatically use the conversation title or timestamp.
6. Click Export Chat again to start. The button will show "Exporting..." during the process.
7. The extension will:
   • Automatically scroll to load all messages in the conversation (including lazy-loaded older messages)
   • Extract content directly from the DOM (no clipboard needed!)
   • Convert formatting, tables, code blocks, and math formulas to Markdown
   • Remove Gemini citation markers like [cite_start] and [cite:1,2,3]
8. Your exported file will be named: <conversation_title>_YYYY-MM-DD_HHMMSS.md (e.g., My_Conversation_2026-01-18_153012.md)

Supported formatting:

• ✅ Text formatting (bold, italics, inline code)
• ✅ Headings (H1-H6)
• ✅ Code blocks with syntax highlighting markers
• ✅ Tables (converted to Markdown tables)
• ✅ Lists (ordered and unordered)
• ✅ Blockquotes
• ✅ Horizontal rules
• ✅ Math formulas (LaTeX from data-math attributes)
• ✅ Line breaks

Not supported:

• ❌ Canvas/drawing responses
• ❌ Embedded images
• ❌ File attachments

Note: All content is extracted directly from the DOM using the Turndown library, ensuring accurate formatting preservation without clipboard dependencies.

ChatGPT

1. Go to ChatGPT and open any chat conversation.
2. Click the Export Chat button at the top right of the page.
3. Use the checkboxes and selection dropdown to choose which messages to export, just like in Gemini.
4. (Optional) Enter a custom filename, or leave blank to use the chat title or timestamp.
5. Choose your export mode:
   • Export as file (default): Downloads a Markdown (.md) file
   • Export to clipboard: Copies the conversation to your clipboard
6. Click Export Chat again to start. The button will show "Exporting..." during the process.
7. The extension will:
   • Automatically scroll to load all messages in the conversation
   • Use ChatGPT's built-in copy button to extract formatted content
   • Compile all selected messages into Markdown format
8. Your exported file will be named: <chat_title>_YYYY-MM-DD_HHMMSS.md (e.g., My_Chat_Title_2026-01-18_153012.md)

Note: ChatGPT export uses clipboard-based extraction via the platform's native copy button to ensure perfect formatting preservation.

Permissions

This extension requires storage permission for extension settings and clipboardRead permission for ChatGPT exports.

Important change in v4.0.0: Gemini exports no longer require clipboard access! The extension now uses direct DOM-based extraction with the Turndown library to convert Gemini's HTML responses to Markdown. This provides:

• ✅ More reliable extraction (no clipboard race conditions)
• ✅ Better formatting preservation (direct HTML→Markdown conversion)
• ✅ Enhanced privacy (no clipboard access needed for Gemini)

ChatGPT still requires clipboard access as it uses the built-in copy button for reliable content extraction.
