How to Create Localized A/B Test Variants with Copilot
Localized A/B test screenshots in your IDE with Copilot and ToolRouter.
Tool
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.
