# How to Create Localized A/B Test Variants with Claude

Claude handles screenshot localization as a thoughtful, context-aware process where each market gets individual attention. Ask Claude to adapt text overlays for specific regional audiences, explain cultural considerations behind each translation choice, and iterate on phrasing until the localized copy feels native rather than translated. Its conversational approach is especially valuable for high-priority markets where nuance matters.

## Setup

claude mcp add toolrouter -- npx -y toolrouter-mcp

## Steps

1. Connect ToolRouter: claude mcp add toolrouter -- npx -y toolrouter-mcp
2. Ask Claude: "Create three text variants of this screenshot for the German market for A/B testing"
3. Claude generates multiple localized variants with different messaging angles
4. Upload variants to App Store Connect product page experiments

## Example Prompt

```
Generate three German-language variants of my first App Store screenshot. Each should use a different headline angle -- one benefit-focused, one feature-focused, one social-proof-focused.
```

## Tips

- Test one variable at a time for clear A/B test results
- Ask Claude to explain the messaging strategy behind each variant
- Run tests for at least two weeks per market for statistically significant results
