Build survey and select AI IntelligenceCompare more than two options
Build a cascading winner series.
Start with A vs. B, then automatically advance each winner against the next challenger. Three options create two head-to-head questions; five options create four. Every round uses the same response target.
Choose 25–1,000 responses per question. Cascades use an odd response target, up to 999, to avoid ties. Need us to recruit respondents? We will confirm audience availability, timing, and price before you pay.
