## Good to know

OPML carries hierarchy and text only, which is exactly what an outliner needs.

The extension creates files on your computer. It does not sign in to OmniOutliner, and nothing is sent to OmniOutliner until you import the file yourself.

## Frequently asked questions

### Does NotebookLM have a built-in OmniOutliner integration?

No. Gemini Notebook has no built-in connection to OmniOutliner. The working route is a file: export from NotebookLM in a format OmniOutliner reads (OPML), then import or open it there.

### Can a slide deck become an outline too?

Yes, with Pro: see [export slides to an outline](https://nlmexporter.com/guides/export/slides-to-outline).

### Does my content pass through a server on its way to OmniOutliner?

No. Files are converted in your browser and saved to your downloads folder. You move them into the other app yourself.
