A few useful answers
Before your first study.
Use it when you need an early read on a problem, a comparison of possible solutions or a check on likely UX friction. The findings help you decide what to investigate and test with real customers.
Depth interviews, concept tests and UX tests are available through compatible MCP clients. You can also run these studies, plus ad testing, in the Sunzu web app.
Sunzu creates audience characters grounded in customer evidence and enriched with a behavioural corpus. They are simulations. Use findings to explore directions and sharpen questions; lived experience, unexpected behaviour and consequential decisions still need research with real people.
