Synthetic personas for researchers

ActualSimulation

Turn real interviews into a living persona you can interview back — voice to voice, grounded in verbatim evidence. One interview becomes a persona you can question and a synthetic panel you can measure, any time.

What it's for

A participant in the room when there isn't one. Pressure-test messaging, explore a segment, and rehearse hard questions against a persona built from real evidence — not a vibe.

Built for UX researchers, strategists, and product teams who need fast, faithful answers between rounds of live research.

How it works

01

Intake

Upload interview transcripts — or run an AI-moderated, voice-to-voice interview with your participants. Speech is transcribed and mined for evidence automatically.

02

Source & approve

Actual Simulation proposes enrichment from public signals. You approve every source before it can shape the persona — nothing enters without your sign-off.

03

Synthesize

A living persona is composed from the evidence: traits, motivations, and a contradiction map — every claim cited back to the verbatim line it came from.

04

Interview

Talk to the finished persona in real time, voice to voice. Ask the questions you wish you'd asked — it answers in character, never beyond the evidence.

From one evidence base

The same grounded evidence powers two modes — go deep with one voice, or broad across a synthetic audience.

Interview

Talk to a single persona, one to one — voice or text. Qualitative depth: ask follow-ups, probe motivations, and hear it answer in character, never beyond the evidence.

Panel

Measure how a whole synthetic audience reacts to a concept, message, or price. Free-text reactions are mapped to rating distributions you can calibrate against real survey data — directional, fast, and traceable to the evidence.

Why it's different

Voice to voice, both ways

Interview real participants by AI voice during intake, then interview the synthetic persona by voice once it's built. No scheduling, no transcription lag.

Grounded, not guessed

Every statement traces to a verbatim excerpt — open any claim to see its source. The persona can't assert what the evidence doesn't support.

Keeps the contradictions

Real people hold opposing views. The contradiction map surfaces those tensions instead of flattening them into a tidy, misleading average.

Your prompts, not a black box

Tune the system prompts behind the interviewer, the synthesis, and the persona's voice — set them per project, or override per study.

Grounded in evidence

Every persona claim is backed by verbatim excerpts from your interviews and approved sources.

Private by default

Projects are scoped to your team. Data stays in your account and is never used for model training.
