Copilot HTML Export Pro από dev-chris

⚠ IMPORTANT UPDATE (September 2026): Microsoft recently introduced major structural changes to Copilot's backend API and migrated to the new copilot.com domain. As a result, the current version( v. 1.0.3) is temporarily broken.

I am actively developing a major update to transition the extension to Manifest V3 and align it with Microsoft's new infrastructure. Work is underway to fully restore all export features as soon as possible. Thank you for your patience while I work on this fix!


Copilot HTML Export Pro provides reliable, private chat backups in a layout that mirrors Copilot’s own interface. Copilot’s “Send a copy” cloud share link has strict size limits: long chats simply cannot be shared. This extension removes that barrier completely, allowing you to export any length of conversation in Copilot-styled HTML or Markdown, from short exchanges to multi-hour sessions, without errors or truncation. You stay in full control of your data — no cloud links, no size limits, no failed shares.

• Fully local processing — no tracking, no cloud servers, no data retention.
• No browser storage needed: exports are generated on-the-fly and saved only where you choose.
  Minimal permissions: only accesses Copilot and Bing domains to pull your chat history and images, plus clipboard access strictly to copy text layouts.

• Search bar with clear Copilot-style text highlighting.
• Built-in filters for code blocks, tables, images, links, and liked messages.
• Automatic grouping by date, role, or conversation pauses.
• A fast Copilot-styled sidebar for smooth navigation through large chats.

• Preserves formatting, links, and references with high fidelity.
• Interactive code blocks that collapse or expand with a single click.
• Simple print option that works even on filtered messages.
• Export filtered messages again as a clean, standalone HTML file.
• Extracts hidden AI image prompts and writes them directly beneath each image.
• Fast navigation in very long chats (5000+ messages) using an efficient virtualized layout, so even huge HTML exports stay smooth and responsive.

1. Log in to Copilot and select your chat in the copilot sidebar.
2. Open the extension and select Load Chat.
3. After loading is finished, choose your export format (HTML or Markdown).
