Most people generate a mind map, look at it for ten seconds and move on. That misses the point: every node is a clickable entry into your sources, and the shape of the map tells you what your notebook is missing.

**NotebookLM was renamed Gemini Notebook** in July 2026. This guide covers the same product under its new name — everything below still applies whether you know it as NotebookLM or Gemini Notebook.

> **Quick answer**
> Click **Mind Map** in the Studio panel. NotebookLM builds a branching diagram of the concepts across your selected sources. Zoom and collapse branches, **click any node to open a chat scoped to that topic**, and use the download button to export the current view as a PNG.

_The map is built from your sources only. Branches mirror what your notebook actually covers._

## Clicking nodes is the actual feature

Click a node and NotebookLM opens a chat question scoped to that branch. This changes how you explore a big notebook: instead of inventing questions from a blank input box, you browse the map, find the branch you care about, and drill in. For a fifty-source notebook it is the closest thing to a table of contents that spans everything.

## Read the map as a gap report

The map is generated from your sources, so its shape is diagnostic. A branch with one thin twig where you expected a canopy means your notebook barely covers that topic. Students use this to find the lecture they skipped; researchers use it to decide what to source next; writers run it on their own drafts to see which subplot is underdeveloped. The weak branches are your to-do list.

## Getting a better map

- **Rename sources first.** Source titles feed the map. Descriptive names produce meaningfully better branch structure than `document(3).pdf`.
- **Scope with checkboxes.** A map of two selected sources is tighter and deeper than a map of all fifty. Generate several scoped maps rather than one mega-map.
- **Collapse aggressively.** Fold away the branches you know. What remains is the part of the material you have not internalized yet.

## Exporting and sharing

The download button exports a PNG of the map as currently expanded, so collapse the noise before exporting. Anyone you [share the notebook with](/guides/notebooklm-sharing-collaboration) can open the interactive map themselves. For a document version of the same structure, generate a study guide or briefing doc from the same sources and [export that to PDF](/guides/export-notebooklm-study-guide); map plus document covers both ways people like to review.

## Limitations worth knowing

- There is no in-place regeneration. If sources changed, delete the map and generate a new one.
- Mind maps are not available in the mobile app; this is a desktop feature.
- Free accounts can generate 10 mind maps per day, Pro 100. Scoped regeneration burns through that faster than you would expect.

## FAQ

### How do I create a mind map in NotebookLM?

Open your notebook and click the Mind Map tile in the Studio panel. The map generates from the sources currently selected in the Sources panel.

### Can I edit a NotebookLM mind map?

You can expand and collapse branches, but not add or edit nodes. To change the content, change the source selection and regenerate.

### How do I export a mind map?

The download button saves the current view as a PNG. Collapse irrelevant branches first, since the export reflects the expanded state.

### Is NotebookLM the same as Gemini Notebook?

Yes. Google renamed NotebookLM to Gemini Notebook in July 2026 — it's the same product, same features, just a new name.
