User Studies

Run UX research, surveys, and A/B studies with AI personas.
19,494 simulated participants across 7 studies on this application. Each run is replayable step by step, and every quote links back to the persona that said it.
1Persona-user

One (persona, user_index) participant. 12 personas × 857 users = 10,284 independent samples, each judged individually.

2Respondent, not estimator

A simulated respondent emits only what a person could: a choice, a stop step, free text, an ordinal certainty. Never a probability.

3Counts → rates on read

Rollups store counts frozen at finalize. Every rate, bound and gate is recomputed on read by one estimator, so what-ifs can't drift.

4Evidence by reference

persona-summary → study-summary. A finding's strength is the number of distinct personas quoted, never a self-graded confidence.
