Before you survey anyone
Know what your survey will find, before you send it.
Pressure-test a questionnaire and estimate what you'll find, before spending the time, money, and goodwill it takes to ask real people.
- No credit card to start
- Two engines: statistical or persona-based
- Verify against real responses, whenever you're ready
Two ways to simulate, one way to check your work
Pick the engine that matches what you need to learn, then hold it up against real responses when you collect them.
Statistical engine
Sample from demographic and behavioral distributions to estimate response patterns in minutes.
Persona engine
Generate AI respondent personas who answer in their own words, for research that needs texture, not just numbers.
Compare to reality
Run the same questionnaire as a live survey later, and see exactly where the simulation was right — and where it wasn't.
How it works
-
01
Build your questionnaire
Write it from scratch, import from Google Forms, or draft it with AI assistance.
-
02
Define your audience and simulate
Describe who you're studying, pick an engine, and get a full set of simulated responses.
-
03
Review, then verify against reality
Read the analysis now, and compare it against real respondents whenever you collect them.
Why verify
Simulation without a check is just a guess dressed up as data.
Typical AI simulation
- Runs once, presents the output with confidence
- No way to know if it matched real people
- You find out you were wrong after the budget's spent
SimuData
- Runs your exact questionnaire, not a paraphrase
- Send the same questionnaire as a live survey later
- See exactly where the simulation matched — and where it didn't
Pressure-test your next questionnaire.
