Yes. To export NotebookLM mind maps to OPML, open the mind map in Studio, choose Export and pick OPML. It is free in NotebookLM Ultra Exporter, with no daily quota and no account. You get a structured outline file that outliners and mind-mapping tools import as a hierarchy.

## Quick facts

## Steps

1. Install [NotebookLM Ultra Exporter](https://chromewebstore.google.com/detail/notebooklm-ultra-exporter/afchokljnhhggkhedfbmkcmdagjmjchj) in desktop Chrome, then refresh any open NotebookLM (Gemini Notebook) tab.
2. Open the mind map in Studio, click the export entry and wait for the extension to read the map. Then follow Choose output, Confirm content, Download.
3. Choose **OPML** in the list of outputs and set any options shown for it.
4. Open the downloaded file and check it before you rely on it or share it.

## What you get

You get a structured outline file that outliners and mind-mapping tools import as a hierarchy.

OPML is the common denominator between outliners such as Workflowy, Logseq, OmniOutliner and mind-map tools.

## Limits to know before you export

- The extension reads the available tree data. If Google changes the page, check the node count and preview before downloading.
- Target apps differ in how they import OPML and FreeMind styling and layout.
- Images use automatic layout, so they will not match the on-screen arrangement exactly.

## Can NotebookLM export mind maps on its own?

Gemini Notebook shows mind maps interactively and can at most save a picture of the map as it is currently expanded. It does not export an editable outline or mind-map file. Google changes these menus often. The item's own menu in your notebook shows what is built in today.

Yes. It is a basic format with no daily export quota, no account and no payment card. Free batches are limited to 5 items.

### What is OPML used for?

OPML is an outline exchange format. It carries the node hierarchy and text, not colours or positions.

### Can I export just one branch of a NotebookLM mind map?

Yes. The whole map is selected by default; choose one branch to export that node and all its descendants, with the parent path kept as context.
