Synthetic populations, real questions
Ask a synthetic population before you ask a real one
Describe the people you care about. Studio builds them, asks your questions, and shows who leans which way, and why.
No card needed. Three guided studies are on us, and the free plan has one population of up to 1,000 people.

Real places
Each filled square has a template of its own. Choose one to see who lives there.
What it is good for
- Pre-testing a policy before announcing it
- Finding the wording that backfires
- Seeing which groups to worry about
- Deciding which questions deserve a real survey
- Teaching and exploring how opinion forms
- Building believable worlds for stories and games
What it is not
- Not a survey. AI answers for invented people. Never present them as real views.
- Better at contrasts than levels. Which groups lean which way, not exact percentages.
- Only as informed as you make it. A good briefing makes all the difference.
- No real people's data. Describe groups with proportions, never records.
