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

Copilot integrates screenshot localization into your build pipeline, enabling batch processing of entire screenshot sets across all target languages from your IDE. Keep localized assets version-controlled alongside your source screenshots and trigger re-localization as part of your release workflow. This approach ensures no language falls behind when you update your base screenshots.

## Setup

{"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}

## Steps

1. Add ToolRouter to Copilot MCP config
2. In Copilot Chat: "Create A/B test variants of these screenshots for the Spanish market"
3. Copilot generates multiple messaging variants per screenshot
4. Export variants for upload to your A/B testing platform

## Example Prompt

```
Generate two Spanish-language variants for each of my App Store screenshots. Vary the headline messaging for A/B testing.
```

## Tips

- Automate variant generation as part of your localization pipeline
- Track test results per market in your repo for data-driven iteration
- Copilot can generate variants for multiple markets in one batch
