How are the personas built?

From what we know about your audience: who they are, what they're trying to do and the devices they use.

A short report per build: the tasks attempted, where each persona hesitated or gave up, and screenshots.

Is this a Zelvorm first?

Yes. We haven't seen another agency run AI persona testing on every staging build as standard.

Industry firstPortal

Five AI customers test every build before you do.

Ghost Users are five AI personas modelled on your real audience. Each time there's a new staging build, they try to complete the tasks that matter, like buying, booking or signing up, and report where they hesitated, got confused or gave up, with screenshots. The team fixes what they find before the build reaches your review.

The difference

The usual way

Usability problems surface too late

Real user testing is valuable but slow and costly, so it happens once, if at all, and problems are found after launch.

With Ghost Users

Testing on every build

Ghost Users run on every staging build, so obvious friction is caught and fixed continuously, and real user testing can focus on the subtle things.

Questions

Ghost Users, answered.

AI personas modelled on your real audience navigate each staging build and report where they hesitate, get confused or give up, with screenshots, before your review.

No. They catch common friction early and often. We still recommend testing with real people for nuanced questions about your audience.
