Personas

Create AI personas of your user base, and ask them questions
Every persona below is a reusable, evidence-backed participant. It answers surveys, drives A/B comparisons, reacts to journeys in UX research and runs QA flows — and every quote it produces is attributed back to it by reference.
1Base layer

Drawn from Persona OS: 3M+ real profiles across ~120k job titles. Sets role, seniority, demographics and industry priors.

2Grounding layer

Your Knowledge, uploaded transcripts and Grounding Rounds enrich the persona with what real users actually said.

3Behavioural layer

OCEAN traits and MBTI shape how the persona reads pages, tolerates friction and decides — so two personas act differently on the same screen.

4Seats in a run

A persona can Drive (act, step by step) or Ride (observe and react). Each persona-user is an independent sample, so 12 types become 10,000 participants.
