Good to know
One note per file works best. Export notes individually or in a batch rather than as one merged document.
The extension creates files on your computer. It does not sign in to Heptabase, and nothing is sent to Heptabase 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 Heptabase integration?
No. Gemini Notebook has no built-in connection to Heptabase. The working route is a file: export from NotebookLM in a format Heptabase reads (Markdown, Markdown outline), then import or open it there.
Can a NotebookLM mind map become a Heptabase whiteboard?
Not automatically. Export the map as a Markdown outline and use it as a card, or rebuild the layout from it.
Does my content pass through a server on its way to Heptabase?
No. Files are converted in your browser and saved to your downloads folder. You move them into the other app yourself.
