# How to Restyle Screenshots for A/B Testing with Copilot

Copilot brings screenshot restyling into your development workflow, letting you manage visual asset updates alongside your code releases. Trigger style refreshes as part of your deployment pipeline, keep design variants version-controlled for A/B testing, and batch-process screenshots across all device sizes in one session. This developer-centric approach ensures your App Store visuals stay current with every release.

## Setup

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

## Steps

1. Add ToolRouter to Copilot MCP config
2. In Copilot Chat: "Generate A/B test design variants for these App Store screenshots"
3. Copilot produces visual style variants for testing
4. Deploy variants through your experiment pipeline

## Example Prompt

```
Create dark-mode and light-mode variants of my App Store screenshots for A/B testing.
```

## Tips

- Track A/B test results alongside variants in version control
- Automate variant generation for systematic design testing
- Build a library of tested designs to inform future creative decisions
