FAQ

​

What is Semilattice?

Semilattice shows you how your users will react to your work before they see it. Simulated users built from real human data answer questions about a plan, a message or an idea, or go through a page or a flow, and you get back what to change. See How Semilattice works.

​

What’s a user model?

A simulated version of a specific group of people, such as UK adults thinking about their finances. It is built from real human data and simulates hundreds of respondents, each modelled on one real person, so you can see where opinions split. See User models.

​

Can I use it from my own AI agent?

Yes. Connect Claude, Claude Code, Cursor or any other MCP client, and your agent can plan and run simulations on the same projects you see in the app. See Semilattice MCP.

​

How accurate are the predictions?

Every user model’s page shows its accuracy, measured against how real people answered questions the model was not built from. On held-out questions, Anacreon, the engine behind our user models, reaches an ordinal alignment of 0.775, ahead of every published academic baseline. See Trust & measurement and the technical report.

​

Can I use my own data?

Yes. With Semilattice Custom we build a user model of your users from your own research: interviews, reviews and open-ended survey responses. It is private to your organisation and tested for accuracy before you use it. Your data and the model remain yours. Book a call.

​

What do you do with my data?

We use it to build and operate your user model, and nothing else. Your data is never used to train other customers’ models, never accessible to other customers, and never used to train foundation models. We do use aggregate performance metrics, such as accuracy scores, to improve how we build models in general, which is not the same as training on your content. See Security and Privacy.

​

What kinds of questions can I ask?

In a User Research simulation, every question is single-choice on a scale, and every simulated user answers all of them. That covers feature preferences, reactions to a price, how a message reads and what people intend to do. To see what people do rather than what they say, a User Journey simulation sends simulated users through a page or a flow.

​

How is this different from traditional research?

A research study takes weeks. Semilattice returns results in minutes, so you can check the decisions that would otherwise be made on instinct. It doesn’t replace deep qualitative research. Use it to find out where your work needs changing before you spend on it, and to decide what is worth a full study.

​

How much does it cost?

The Base and Org plans include a 1-month free trial, which starts when public Anacreon user models launch in November 2026. You can create an account now. See pricing.

How do I get started?

Create an account, or connect your agent. If you want a user model of your own users, book a call.
