A free online mind map maker — no signup. Type an outline under a central idea and get a live mind map, rendered server-side as SVG (a Mermaid mindmap). It's real-time collaborative: share the board URL and everyone edits the same mind map together. The fastest way to make a mind map online, free.
Click the button above and you land on a fresh board with this mind map already rendered. Edit the outline in the text node — indent lines under root((Idea)) to branch out — and the mind map re-renders. This is the exact source the maker opens with:
