# A/B 创意实验室

> Generate multiple ad creative variations instantly to test different copy, colors, layouts, and styles

## 概览

A/B Creative Lab generates multiple variations of your ad creative automatically, allowing you to test different approaches without manual design work. Upload one creative and get 4-10 variants testing different copy, colors, layouts, emotional appeals, and more.

## How It Works

1. **Upload Original Creative**: Upload your base ad image or creative
2. **Add Context**: Enter product name, headline, and CTA
3. **Select Variation Type**: Choose what aspect to test
4. **Set Variant Count**: Choose 4, 6, 8, or 10 variants
5. **Generate**: Create all variations instantly
6. **Pick Winner**: Vote for the best performing variant

## Variation Types

Choose from 6 different variation approaches:

### Copy Variations ✍️

Same image, different headlines and CTAs. Test messaging impact.
