Semilattice is an audience simulation platform. It builds AI models of specific audiences, grounded in real survey data, that predict how those audiences would answer questions they’ve never been asked. Research-grade signal in seconds, not weeks.
Accuracy depends on the population model and the type of question. Our UK Consumer Finance model scores 91% accuracy against the FCA Financial Lives Survey, on 207 questions it had never seen. Every prediction comes with an accuracy estimate so you know how much to trust it. Read the full validation →
A population model represents a specific group of people: UK adults interested in consumer finance, developers, engineering managers. It’s built from real survey data and uses that data to predict how the group would answer new questions. You can use our public models or create custom ones from your own data. Learn more →

Single-choice and multiple-choice questions. Anything you’d put in a survey: feature preferences, pricing sensitivity, competitive perception, behavioural intent. The model works best with questions that have distinct answer options.
Traditional research takes weeks and costs thousands. Semilattice returns predictions in seconds at a fraction of the cost. It doesn’t replace deep qualitative research. It fills the gap between gut instinct and a full study, giving you signal before you’ve committed to a direction.
Choose a population model, send a question with answer options, and poll for results. Predictions typically return in ~20 seconds. Available via Python SDK, Node.js SDK, or REST API. Quickstart →
