Freeplane

Freeplane is a free and open-source software application that supports thinking, sharing information and getting things done at work, in school, and at home. The software can be used for mind mapping and analyzing the information contained in mind maps. Freeplane runs on any operating system that has a current version of Java installed. It can be run locally or portably from removable storage like a USB drive.

Features and Highlights

• Note-taking with freely positionable, unconnected nodes (post-it’s);
• Ordering ideas (nodes) into a hierarchy connected by lines (edges);
• Classifying nodes with metadata (attributes) and style types (system styles, user-defined styles, level styles);
• Grouping nodes with visual containers (clouds) and accolade (summary node);
• Connecting nodes with dynamic links, free lines (connectors) and labels;
• Automatically styling nodes (with a bubble, color, edge type, etc.) according to hierarchical level and content (conditional styles, automatic edge color, level styles);
• Structuring nodes in terms of content (text, scientific formula, calculation, icon, image, and hyperlink) and presentation area (core, details, notes, attributes, images, and tooltip);
