Key Features

Parallel Generation
All variants generate simultaneously — a 10-variant test takes roughly the same time as generating a single image, not 10x longer.

6 Distinct Variation Axes
6 Distinct Variation Axes
Each variation type tests a fundamentally different hypothesis. Don’t just test colors — test the emotional angle, the audience targeting, the layout, and the copy in separate A/B rounds.
Testing Strategy
Test One Variable at a Time
For meaningful A/B test results, test one variation type per round. Don’t combine color changes with copy changes — you won’t know what drove the difference.Recommended Testing Order
- Copy Variations — Headline and CTA have the highest impact on ad performance
- Emotional Angles — Fear, excitement, trust, urgency all perform differently
- Color Schemes — Colors affect attention and emotion
- Layout Shifts — Element hierarchy and composition
- Audience Targeted — Once you know the message, test different presentations per segment
- Style Transfer — Broad aesthetic change for brand positioning tests
