Zersona is a decision-support tool for product teams
who don’t have users yet.
It simulates diverse AI personas to help you
stress-test assumptions, explore conflicting opinions,
and refine questions before real user research.
Zersona doesn’t replace interviews.
It helps you think earlier — when decisions still feel uncertain.

Hey Product Hunt 👋 I built Zersona because I kept making product decisions before I had real users to talk to. Zersona simulates diverse AI personas so you can challenge assumptions and surface blind spots before committing to a direction. It’s not meant to replace user interviews — just to help you think earlier, when things are still fuzzy. I’d love to hear how you currently validate ideas...
