A Multiple-Hierachical Information Manager
A lot of programs allow you to classify things in more than one category, and others use tree-like ("hierarchical") organization. Only TheKBase combines both.
TheKBase is a way to organize information in a hierarchy. If you want, you can use it like a notepad with a tree-like structure.
But hierarchical structures are limiting. Often, you want to classify information in multiple ways. TheKBase allows you to do just that, either collaboratively on the Web (TheKBase Web), in a standalone Windows .NET version, and in a Windows Mobile version.
