How does iMario work?

iMario creates Synthetic Individuals: persistent AI agents with stable identity, bounded expertise, and human-like memory. Each individual is built through a multi-phase pipeline that generates a foundational personality, validates it against behavioral benchmarks using an expert reflection panel (demographer, psychologist, economist), and maintains consistency through working, episodic, and semantic memory layers. You can then interview them, test concepts with them, rehearse sales calls, or plug them directly into your own AI agents via API.

What are Synthetic Individuals?

Synthetic Individuals are constrained AI agents designed to simulate specific people, not generic personas or freeform roleplay. They maintain stable identity over long conversations (96% consistency), operate within bounded expertise so they never hallucinate credentials they don't have, and carry persistent memory across working, episodic, and semantic layers. Built through iMario's harness-engineered pipeline with expert reflection and validation loops, they represent a new computational primitive: reusable, stateful components of a human world simulator.

Can Synthetic Individuals really replace real human participants?

For the vast majority of research and rehearsal use cases, yes. Synthetic Individuals deliver 92% behavioral parity with human cohorts on concept testing, messaging validation, usability studies, onboarding rehearsal, and sales objection practice. They excel exactly where real-world access is slowest and most expensive: doctors, executives, regulators, and niche consumers. For final validation or highly specialized populations, we recommend combining synthetic insights with selective real-user testing.

iMario is built for product teams, UX researchers, sales leaders, and founders who need human insight faster than traditional research allows. It's especially useful when the audience is hard to reach (physicians, executives, regulators) or when the interaction has to go right the first time (sales calls, launches, onboarding). AI teams also use iMario to ship production agents with a stateful human layer on top via API.

Welcome to iMario Docs

iMario is an AI platform for synthetic user research — you create virtual users (Synthetic Individuals) who think, remember, and respond like real people, then run interviews, content tests, and sales rehearsals against them.

These docs cover everything from setting up your first study to writing discussion guides and interpreting reports.

Start here

Getting Started — Run your first synthetic user study end-to-end in under 30 minutes.
Creating Effective Discussion Guides — Turn research questions into conversations that produce real insight.
Interpreting Research Reports — Read the report, extract decisions, and share findings.

Platform model

iMario is persona-centric: you create and refine virtual users first, then run tasks (interviews, quick tests, direct chats) against them. A Discussion Guide is just one of many task types you can run.
