  description

  Threadmark is a Chrome extension for ChatGPT and Claude that lets you save, organize, and export AI conversations, prompts, and responses across both platforms.
  
  Bookmark, highlight, branch, and manage your best ChatGPT and Claude ideas in one unified workspace layer — without copying into separate apps.
  
  🚀 What’s New in 1.0.6.1
  
  Threadmark now works across both ChatGPT and Claude.ai, so your ideas are no longer trapped inside one AI.
  
  🧠 Claude.ai Support (Feature Parity)
  Save full messages and highlighted snippets on Claude just like ChatGPT — with hover dots, + Save, return-to-message, and branching support.
  
  🔁 Cross-AI Idea Workflow
  Capture something in ChatGPT. Refine it in Claude. Branch it back again.
  Threadmark lets you collect, revisit, and reuse ideas across both platforms with less friction.
  
  🎯 Movable Floating Action Button
  Drag the FAB freely, then release to snap to the nearest safe corner. It snaps cleanly into corner positions for a polished workspace fit.
  
  ⚡ Performance & Reliability Improvements
  Faster saves, smoother interactions, and improved compatibility with modern ChatGPT and Claude layouts.
  
  ⸻
  
  Turn AI Chats Into a Real Workspace
  
  AI tools generate incredible ideas.
  But they’re built like conversations — not workspaces.
  
  Threadmark adds a lightweight memory layer on top of ChatGPT and Claude so you can:
  
  • Save only what matters
  • Organize ideas into folders
  • Instantly return to key moments
  • Branch into new conversations
  • Export cleanly when it’s time to ship
  
  No more endless scrolling.
  No more re-asking the same question.
  No more scattered notes.
