Semantik (previously Kdissert) is a mindmapping-like tool to help students to produce complicated documents very quickly and efficiently : presentations, dissertations, thesis, reports. While targetted mostly at students, Kdissert can also help teachers, decision maker, engineers and businessmen. Semantik is also available exclusively for Linux and other free operating systems.

Though this application shares some similarities with general-purpose mindmapping tools like Freemind or Vym, the very first goal of Semantik is to create general-purpose documents through the use of mindmaps.
