Mubu

About

Mubu (幕布) is an outline and mind-map tool for organizing knowledge, work, and everyday life. Its outlines let you break complex material into nested levels, so scattered notes can fit into a clear framework. Templates cover areas such as study planning, exam preparation, work meetings and progress tracking, and travel plans, and bidirectional links connect related information into a knowledge network.

The app is built for fast, keyboard-driven writing. It supports Markdown input and LaTeX formulas, offers shortcuts across all scenarios, and is said to open very large documents quickly. Mubu is available on Mac, Windows, iPhone, iPad, Android, and the web, with cloud sync across platforms.

Mubu also supports collaboration. You can send a link so a team can edit together, and you can share your knowledge with other users. A free version is available, along with a premium version.
