Infocard Workbench is a thought-enhancing tool (currently console-based) for reading and organizing "electronic notecards," called infocards, stored in the InfoML format (see http://InfoML.org). In this way, users can store and explore large numbers of loosely-connected, tagged "chunks" of human-readable data. Typical uses include organizing research materials (for papers, novels, etc.), brainstorming, and searching a knowledge base of domain-specific information.
