We describe the development of the Designers’ NotePad; a tool to support the rapid creation and refinement of ideas. The tool supports collaborative dialogues with features that enable idea fragments to be rapidly entered and revised. The core features are entities and links. Users are able to gradually add more structure while still keeping the freedom to rapidly refine and without being required to make premature commitments about classification. An iterative design approach was used involving frequent studies of the tool in use. Particular attention is given to the impact of the interface on the usability and effectiveness of the system.
