Introduction
Get started with Semilattice’s API for user simulation
Semilattice is a user simulation API that predicts how specific user profiles would answer questions. Our API lets you simulate responses from any user profile, from general consumers to software developers to niche user segments you define with your own data.
How it works
- Choose a population model - Select from ready-to-use public population models or create your own
- Simulate answers - Simulate how the population would answer questions to predict behaviour
- Orchestrate simulations - Combine multiple answer simulations to produce more complex prediction outputs

Core concepts
Populations
Population models represent specific user profiles. Learn how to choose the right population for your use case.
Answers
Answer predictions show how populations respond to questions. Understand simulation vs benchmarking.
