NotebookLM to ChatGPT: reuse notes and chats as context
Short answer
To continue NotebookLM work in ChatGPT, export the notes, report or chat to Markdown with NotebookLM Ultra Exporter, which is free, and upload the file to a ChatGPT chat or project. ChatGPT then has the grounded summary and its citation markers as context.

Good to know
The export carries the text and citation markers, not the source documents themselves. Attach key sources too if ChatGPT needs to quote them.
The extension creates files on your computer. It does not sign in to ChatGPT, and nothing is sent to ChatGPT 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 ChatGPT integration?
No. Gemini Notebook has no built-in connection to ChatGPT. The working route is a file: export from NotebookLM in a format ChatGPT reads (Markdown), then import or open it there.
Can I go the other way, from ChatGPT to NotebookLM?
Does my content pass through a server on its way to ChatGPT?
No. Files are converted in your browser and saved to your downloads folder. You move them into the other app yourself.
