ChatTree: Conversation Map for Claude.ai

ChatTree adds a tree-map navigation panel to your Claude.ai chat sessions, so you never lose your place in a long conversation. Keep it floating over the page, or dock it as a sidebar beside the chat. As you chat, ChatTree automatically detects every message and branch and lays them out as a clean, navigable tree. Click any node to jump straight to that message — the page scrolls right to it. The currently visible message is highlighted, and the tree auto-scrolls to keep it in view. NEW IN 2.0 • Sidebar mode — dock the panel beside the conversation instead of floating over it, with a toggle button right in Claude's top-right action bar • Interactive Map — a second board below the tree that you can pan, zoom, and rearrange: drag an edge to re-parent a node, disconnect a branch, or give your branches names • On-device AI summaries (optional) — label every message with a keyword and open the full Q&A with one click, all computed on your own machine • Collapse messages from either side — hide a node in the tree and it collapses in the chat too, and the reverse • Your tree now survives a browser restart, so long conversations no longer come back truncated • Get notified when Claude finishes writing, so you can look away and come back when the answer is ready KEY FEATURES • Tree-map overview of the whole conversation, including branches • Interactive Map with pan, zoom, and hand-editable connections • One-click jump to any message • Active-message tracking with auto-scroll • Bookmark important messages within a session • Tag messages to organize them your way • Search to find specific messages in the current chat • Sort the message list to suit your workflow • Hide messages you are done with, in the tree and in the chat • Clear multi-branch indicators for conversations with edits/regenerations • Floating or sidebar layout, resizable and collapsible, with light / dark / auto themes • Korean and English language support ABOUT THE ON-DEVICE AI The AI summary feature is entirely optional and turned OFF until you switch it on in the panel settings. When enabled, it runs two models locally: Chrome's built-in Gemini Nano writes the summaries (Chrome downloads it once, with your confirmation, and it needs Chrome 138 or newer), and a small embedding model bundled inside the extension relates messages to one another. Your conversations are never uploaded, and if your browser does not support the built-in AI, ChatTree simply tells you so and everything else keeps working. PRIVACY ChatTree runs only on Claude.ai. All of your settings, session data, and any AI summaries stay on your device — nothing is ever collected, transmitted, or shared. The extension makes no network requests of any kind. No account, no tracking, no external servers. ChatTree is open source. Feedback and contributions are welcome on GitHub.
