Mind mapping

Cayra is a free desktop application that lets you represent tasks, ideas, concepts and other items in a graphic, well-structured way. Cayra is based on such visualization techniques, as Mind Mapping and Concept Mapping and allows you to conveniently work with big maps.

FreeMind is a premier free mind-mapping software written in Java. The recent development has hopefully turned it into high productivity tool. We are proud that the operation and navigation of FreeMind is faster than that of Mind Manager because of one-click "fold / unfold" and "follow link" operations.

The IHMC CmapTools program empowers users to construct, navigate, share and criticize knowledge models represented as concept maps. It allows users to, among many other features, construct their Cmaps in their personal computer, share them on servers (CmapServers) anywhere on the Internet, link their Cmaps to other Cmaps on servers, automatically create web pages of their concept maps on servers, edit their maps synchronously (at the same time) with other users on the Internet, and search the web for information relevant to a concept map.
