From the developer:
MindupFree is a free version of MindupPro, an efficient mind-mapping software program, supporting full keyboard and driven by Vim_style shortcuts. It's suitable for meetings or classroom writing in shorthand. It can also present your contents as with Keynote or PowerPoint, but in mindmap style.
