Orchard is a web-based software that supports visual idea clustering. Orchard helps to elaborate and synthesize new ideas from online brainstorming sessions and to generate high-quality ideas (also called idea synthesis). Users can import already collected idea-sparks from, e.g., Greenhouse using RDF. Users can then place ideas on a digital whiteboard, summarize and filter ideas, create clusters based on similar ideas, name these clusters, and get an overview of existing categories. The user can export the results in RDF format again.
