AI-moderated interviewing is bringing qualitative depth to quantitative scale, but can MaxDiff travel with it? This study first tests standard MaxDiff across Web, text chat, WhatsApp, phone, real-time voice and video. A second experiment then asks a broader design question: what kind of MaxDiff works best in each AI-moderated environment? By varying task structure and respondent load, we explore how much MaxDiff each mode can support before measurement quality begins to suffer.
