The Brain mind map is a polycentric mind map. TheBrain is a unique product among various thinking process recording tools - its way of presenting the thinking network is very unique, its node/association relationship expression ability is very strong, the interactive interface is more in line with human intuition, and the editing operation of the thinking network is also quite flexible and convenient (Developed The author has applied for a patent for its interactive interface a long time ago), and node input also supports keyword matching and automatic completion, which is very suitable for building a personal lifelong learning knowledge base.
Common mind mapping software usually centers on a thinking node (and it is difficult to change once determined), and extends around it in two intervals: left and right or upper and lower. Whether it is left/right/top/bottom, the positions of each branch are parallel. If you want to emphasize the difference, you need to manually set the outer frame yourself.
TheBrain is different. It supports any node as the center and is roughly divided into three areas: upper/lower/left. The actual meaning of these three areas can be distinguished by users according to their personal habits. But in any case, their status is different, which can be seen with the naked eye.
