Private, no-signup brainstorming
Give your ideas room to grow.
Brainstorm your next article, explore a project, or break down a goal. Start with one main idea, connect related themes, and develop the details in a structured 9×9 mind map.
Capture ideas, questions, notes, or actions. Use as much of the map as you need; blank cells are welcome.

Local and private
Your thinking stays yours
Autosave keeps your working map in this browser. Use Saved maps to save named copies and load them later. These copies use browser-local storage only: they do not sync to another browser or device. There is no account, cloud save, external AI, or content API.
Your chart and named copies stay in this browser unless you export or share them.
Clearing this site’s browser data removes autosave and named copies. Download JSON for a portable backup, especially before clearing browser data or using private browsing.
