Mind map editor for Gemini Notebook
NotebookLM generates mind maps but cannot edit them. Paste its outline here, rearrange and recolour the branches, then export to Markdown, SVG or PNG — everything runs in your browser.
Frequently asked questions
- How do I get my NotebookLM mind map in here?
- NotebookLM will not export the map itself, but it will happily describe it: ask the chat for “a Markdown outline of this mind map” (or of the topic), copy the answer, and paste it into Import. Headings and indented bullets become branches.
- Is anything uploaded?
- No. Parsing, layout, editing and every export format run in your browser. The map autosaves to this browser's local storage and nowhere else.
- What can I export?
- Markdown (re-importable here and readable anywhere), JSON (the raw structure), SVG (vector, scales to any size), and PNG at 2× for slides and documents.
- How does editing work?
- Double-click renames a branch. Tab adds a child, Enter adds a sibling, Delete removes. Drag a branch onto another node to move it there — the editor refuses moves that would break the tree. Ctrl+Z undoes everything.
