The Synthetic User's Gym · No sign-in required

The gym where preusers train.

A preuser is an AI user — it opens your app and walks a real journey like a person, no test code. Watch one train on a demo below, then sign in to task your own and ring the gong when it graduates.

Pick a demo below. Tasking a preuser is just this: a plain-English goal and the finish line that counts — no scripts, no selectors. Watch one train, then send in your own.

This is everything a preuser needs — a goal and a finish line, in plain English.

Goal ?The goal is the workout you hand a preuser — what a person is trying to do, in plain English. No selectors, no waits. The preuser reads it and goes and does it.
Take the new lead through the pipeline and close the deal.
Success ?Success is the finish line — an independent grader checks it against the final screen. It's how the gong knows to ring.
