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

ChatGPT excels at generating multiple screenshot style variants while explaining the design reasoning behind each option. It can suggest which visual approaches typically convert best for your app category, produce before-and-after comparisons with strategic rationale, and create presentation-ready style guides that document the visual language across your screenshot set. Perfect for teams that need to present options to stakeholders.

## Setup

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

## Steps

1. Configure ToolRouter in ChatGPT
2. Ask: "Create design variants of my screenshots for A/B testing"
3. ChatGPT produces multiple visual style variants
4. Select the best candidates for your experiments

## Example Prompt

```
Generate three visual design variants of my hero screenshot. I want to test which style converts best.
```

## Tips

- ChatGPT can suggest which visual elements are most likely to impact conversion
- Ask for variants that test specific hypotheses about your audience
- Document your test results to build a design playbook over time
