GraftMind: Facilitating Group Ideation with AI-Mediated Idea Sharing

In group ideation, whether participants should ideate collaboratively or individually remains controversial. Collaborative ideation enables synergy, whereby creativity is stimulated through inspiration from others’ ideas; yet it also introduces evaluation apprehension, which can inhibit creativity due to fear of judgment. In contrast, solitary ideation mitigates evaluation apprehension but cannot foster synergy. Existing hybrid approaches have attempted to alternate between the two modes to balance their strengths, but it remains underexplored how to simultaneously integrate the advantages of both settings.
