Test ad

before launch

Rehearsals lets you test campaign concepts, storyboards, static ads, landing pages, and value propositions with AI twins before you buy media.

Twins explain what they notice, what feels believable, what makes them hesitate, and which version they would act on. You see the winner and the reasoning behind it.

The output is a clear creative read: the message that lands, the elements to cut, and the language customers use when they describe why they care.

How it works

Upload creative options, define the audience, and let Rehearsals run structured interviews with thousands of twins. The report ranks each option, summarizes the objections, and shows the exact reasoning behind the recommendation.

Why it matters

Creative testing is usually slow enough that teams ship first and learn after spend is committed. Rehearsals gives you directional confidence while the campaign can still change.
