What is Semilattice?
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.
How accurate are the predictions?
How accurate are the predictions?
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 →
What's a population model?
What's a population model?
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 →
Can I use my own data?
Can I use my own data?
Yes. Send us your survey data and we’ll build a custom population model for your audience, tested for accuracy using cross-validation. See the data requirements →
What kinds of questions can I ask?
What kinds of questions can I ask?
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.
How is this different from traditional research?
How is this different from traditional research?
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.
