Quick answer
How to export a mind map from Gemini Notebook
First, install the NotebookLM Exporter Chrome extension linked on this page when you need editable structure rather than NotebookLM's native visual download. Next, open NotebookLM Studio, select the mind map and wait for the map canvas to load. Locate the Export ▾ button at the top of the mind-map canvas. Then, choose Markdown, OPML, FreeMind, HTML, Text or JSON based on the destination tool. Finally, download the file and open it in the compatible outliner, mind-map application, text editor or script.
Why export it?
Why export?
A visual image is useful for sharing, but it is difficult to edit, search or transform. Writers, researchers and planners often need the hierarchy behind the diagram rather than only a picture of it.
