What if you could predict how residents would respond to a policy before it launched? Or get a signal on who will win an election?

This is a synthetic population for cities from census marginals: demographics, neighborhoods, religion, education, migration and polls it with archetype-clustered LLM calls.

Ask any yes/no question, belief forecast, or multi-option poll. The synthetic population clusters residents into demographic archetypes, batches model calls, and aggregates answers with survey weights then reveals the verdict on the map.
