Good to know
This keeps the map as plain text you can version in Git and still view as a diagram.
The extension creates files on your computer. It does not sign in to Markmap, and nothing is sent to Markmap until you import the file yourself.
Free or Pro?
Free, with no daily export quota and no website account needed. Pro covers the extension only; it does not include a Google subscription or raise NotebookLM's own limits. Current prices are on the pricing page.
Frequently asked questions
Does NotebookLM have a built-in Markmap integration?
No. Gemini Notebook has no built-in connection to Markmap. The working route is a file: export from NotebookLM in a format Markmap reads (Markdown outline), then import or open it there.
Why not use the interactive HTML export instead?
Use HTML to share a finished map. Use Markdown with Markmap when you want to keep editing the structure as text.
Does my content pass through a server on its way to Markmap?
No. Files are converted in your browser and saved to your downloads folder. You move them into the other app yourself.
