Compendium is a software tool providing a flexible visual interface for
managing the connections between information and ideas.

Many people use Compendium to manage their personal digital information
resources, since you can drag+drop in any document, website, email, image,
etc, organise them visually, and then connect ideas, arguments and decisions
to these. Compendium thus becomes the glue that allows you to pool and make
sense of disparate material that would otherwise remain fragmented in
different software applications. You can assign your own keyword tags to these
elements (icons), create your own palettes of icons that have special
meanings, overlay maps on top of background images, and place/edit a given
icon in many different places at once: things dont always fit neatly into just
one box in real life.
