MerMindMap
MerMindMap is a free visual mind-map editor in your browser. Brainstorm, plan and organise ideas, then keep them as portable Mermaid text.
Map ideas at the speed of thought
Tab adds a child topic, Enter adds a sibling. Drag branches, zoom and pan freely.
Plain-text Mermaid files
Every map is saved in Mermaid mindmap format, so it works in GitHub, Notion, Obsidian and more.
Optional Google Drive
Save maps to, and open maps from, your own Google Drive. MerMindMap only sees files you choose.
Private by default
Your maps are saved to your account automatically and only you can see them.
Enjoying MerMindMap?
It’s free to use. If it helps you, a coffee helps keep it running.
