Simulating user personas for UX testing

AI simulates realistic merchant personas interacting with the product so design teams can run fast, repeatable user testing without recruiting participants or scheduling sessions.

Why the human is still essential here

The human designer still defines the product context, interprets what matters, and decides which UX issues are worth solving and how to prioritize them.

How people use this

Synthetic merchant walkthroughs

AI roleplays different merchant types and walks through onboarding or setup flows to reveal where each persona gets confused before any live study is scheduled.

Prototype testing with synthetic users

Designers run simulated users through clickable prototypes to pressure-test navigation, copy, and task completion across multiple customer segments in minutes.

Persona-based concept validation

Teams generate AI personas that reflect target customer segments and use them to sanity-check whether a new feature concept fits likely user goals and objections.

My design process at ReferRush right now:

My design process at ReferRush right now:

1.AI simulates 5 real merchant personas using my app
2.A second AI acts as a senior PM silently watching them struggle
http://3.PM writes a friction log with every hesitation, misclick, and almost-uninstall moment
4.A builder AI takes that feedback and rebuilds the entire front end
5.Loop back to step 1

I’m running user testing at the speed of thought with zero recruits, zero scheduling, and zero bias. Each round takes minutes, not weeks.

This two-prompt system is catching UX problems I would have shipped and found out about 3 months later from a 1-star review.
