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.

Ship a release to production read-only

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.
Ship the web-app release to production.
Success ?Success is the finish line — an independent grader checks it against the final screen. It's how the gong knows to ring.
The deploy console shows the release live in production with every pipeline stage green.
