Yes. To export NotebookLM mind maps to interactive HTML, open the mind map in Studio, choose Export and pick interactive HTML. It is free in NotebookLM Ultra Exporter, with no daily quota and no account. You get one self-contained offline file that opens in a desktop browser, where you can expand and collapse nodes, search, pan and zoom. Recipients need no account.

## Quick facts

| Output | interactive HTML (.html) |
| Plan | Free |
| Where | Export entry on the mind map |
| Processing | Converted in your browser. Nothing is uploaded to export. |

## 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 **interactive HTML** 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 one self-contained offline file that opens in a desktop browser, where you can expand and collapse nodes, search, pan and zoom. Recipients need no account.

This is the default output and the best way to share a map with someone who does not use NotebookLM.

## 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.

## Frequently asked questions

### Is it free to export NotebookLM mind maps to interactive HTML?

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

### Can someone open the HTML mind map without NotebookLM?

Yes. It is a single offline file; any desktop browser opens it and no sign-in is needed.

### Do I need to expand every node before exporting?

No. The extension reads the tree data rather than the visible picture, so collapsed branches are included. Check the node count in the preview.

### Can I export several mind maps at once?

Yes. Choose Batch export in the mind map dialog to export every map in the notebook in one format; multiple files are zipped. Free allows 5 results per batch; Pro removes that limit.
