Summary: Freeplane is a mind mapping and knowledge management software. Its easy-to-use interface supports thinking, sharing information and getting things done. Notes can be freely positioned, as unconnected nodes, or as ordered ideas in a hierarchy. Any node can be classified with meta attributes, different manual or automated styling, grouped, connected with links, arrow lines or labels. Nodes can also be structured by content (text, formulas, calculations (LaTeX), images or hyperlinks). It also includes calendaring and reminders, encryption, WYSIWYG and dialog editing, spell checking, publishing and sharing formats, and various search functions.
