Treeport: Mind Map Exporter for Gemini Notebook™

Treeport: export Gemini Notebook™ mind maps to Markdown or OPML. Map stays in your browser; Pro exports send only a license check.

Your exact mind map, every branch, word for word, not an AI re-summary. Treeport turns the map you're viewing in Gemini Notebook (formerly NotebookLM) into a real, editable file you can open in your notes app, outliner or mapping tool. You get the whole tree, down to the deepest branch, not just the levels that are open on screen. WHAT YOU GET • Complete trees: every node is captured, including branches that are still collapsed on screen, with no clicking. The popup shows the count, for example "53 of 53 nodes exported", so you can see that nothing was dropped. • Private by design: the map is read and converted inside your browser. Your notebook content is never sent to us or anyone else. No analytics, no tracking. HOW IT WORKS 1. Open a notebook and its mind map at notebook.google.com. 2. Click the Treeport toolbar button and pick a format. 3. The file downloads to your computer. The first time, you're asked to allow access to the sandbox frame where the map is drawn. This optional permission is requested only when you click, never at install. FREE • Current mind map → Markdown outline or OPML. PRO (optional, via ExtensionPay: $3.99/month, $24/year or $34 lifetime) • JSON tree • FreeMind (.mm) for desktop mapping apps • Mermaid diagram code for docs and wikis • SVG or PNG image of the map (very large maps are saved as vector only) CAN'T THE CHAT DO THIS? The built-in download saves a picture of only the branches you have expanded. Ask the notebook's chat for an outline and it writes a new one from your sources: a re-summary that isn't guaranteed to match your map node for node. When we asked the chat to copy an existing map, it said it can't read the map's contents and offered to build a new one from the sources instead. This extension copies the map itself, word for word, and gives the same file every time. PRIVACY Export processing is fully local and never sends your content anywhere. The free formats contact no server at all. The only network contact is ExtensionPay (extensionpay.com), our payment provider, and only when you run a Pro export, start or restore a purchase, or visit ExtensionPay's own pages: it checks your licence using an installation key, never your notes. Settings stay on this device (nothing syncs). Full policy: https://chrisgrant303.github.io/govcon-data-suite/treeport/privacy.html Gemini Notebook™ and NotebookLM® are trademarks of Google LLC.
