01 / BRIEF
Bring the work in progress.
Upload campaign concepts, static ads, storyboards, landing pages, or video. Then define the audience whose reaction matters.
Know which creative wins before media does.
Put every concept in front of AI twins of your actual audience. See what lands, why it lands, and what to change before the spend goes live.
PROVEN AGAINST OUTCOMES
The signal holds up after launch.
Creative feedback is only useful if it points toward what real customers actually do. We test that connection against observed performance.

THREE STEPS
Brief it. Run it. Make the call.
One Rehearsal takes a live creative decision from rough work to an audience-backed recommendation.
02 / SIMULATE
Watch the audience respond.
Twins compare the options, explain what they notice, and surface the belief, hesitation, and language behind each choice.
03 / DECIDE
Ship with a clear read.
Get the winner, the reasons it won, and the edits most likely to improve it while the campaign can still change.
MERA NYC
Twins picked the ad that produced higher ROAS.
A footwear brand had two very different directions. The result was already waiting inside the audience response.
Before the media ran, the twins preferred Ad B. After launch, Ad B delivered the higher return.
72%of twins chose the real-world winner
Ad A28%
Ad B72%
In a separate test on a third ad, the twins also flagged the loser more than 90% of the time and diagnosed the reason it underperformed.
MORE THAN A SCORE
Keep the reasoning attached to the result.
A winner without an explanation does not help the next round. Rehearsals shows the decision and the audience logic that produced it.
