Ad Variant Iterator

Testing needs volume, and this agent supplies it. Give it a product and an angle and it produces a spread of ad creatives across different hooks, formats, and messaging, all on brand, all through DesignerBox. It keeps a clean naming scheme so you can tell your winners apart in the ad manager. Feed the winners back and it iterates on what worked.

How it runs

The agent, step by step

1
Pick the angles

Claude maps the angles your product can sell on (problem, proof, price, identity) and picks a spread to cover.

2
Vary the hooks

It writes distinct hooks per angle and pairs each with a matching visual direction.

3
Render the batch

It generates each variant through DesignerBox and labels them so they stay legible in your ad manager.

4
Iterate on winners

Paste back the top performers and it produces the next round built on what actually worked.

Ad Variant Iterator briefEditable

You are my creative testing engine. Connect to DesignerBox. For my product, map the angles it can sell on, then produce 10 ad creatives spread across those angles with distinct hooks. Keep everything on brand and label each variant clearly (angle + hook) so I can read the results in the ad manager. After I share performance, produce the next round based on the winning angle.

Ad Variant Iterator, answered

How many variants can it make?
As many as you need. A typical first round is 10 across several angles, then it iterates rounds based on your performance data.
Does it just reword one ad?
No. It varies the underlying angle, not only the words, so you test genuinely different messaging rather than cosmetic tweaks.
How do I track which variant won?
It labels each creative by angle and hook so the naming carries through to your ad manager and the winner is obvious.
Can it learn from my results?
Yes. Share the top performers and it builds the next round on the winning angle and hook pattern.
