Gemini Notebook Mindmap Exporter

Extract mind maps from Gemini Notebook (formerly NotebookLM) with one click; supports exporting in eight formats, clipboard… Gemini Notebook Mindmap Exporter is a focused Chrome extension for Gemini Notebook (formerly Google NotebookLM) that exports the mind map you've built in any notebook into clean, reusable files on your device.

If you've ever wondered "how do I download the NotebookLM mind map so I can edit or share it?", this extension is the answer — and it works with the new Gemini Notebook. It reads the mind map currently shown on the page and rebuilds it locally, so your notes and notebook contents never leave your browser.

• One-click extraction — expand the mind map view, click Extract, and the whole structure is captured in seconds.
• Multiple export formats — save the same mind map as Markdown, JSON, CSV, or other file types, so a single export fits any downstream tool.
• Interactive HTML mind map — get a visual, pan-and-zoom mind map you can open in any browser.
• Xmind-ready copy — paste the copied content straight into Xmind to keep editing visually.
• Copy to clipboard — grab the mind map in your chosen format without saving a file.
• Local extraction history — the last 10 extractions are saved on your device so you can restore or re-export them anytime.
• Stats & preview — see total nodes, max depth, leaf count, and a collapsible structure preview before you export.
• Works entirely on-device — all reading, parsing, and file generation happen in your browser; nothing is uploaded.

Install this Chrome extension, open your notebook, expand the mind map view, click Extract, then pick a format and download — your file is ready in seconds.
