# Create A/B Test Variants for Localized Screenshots

The best-converting screenshot text in English is not necessarily the best in German or Japanese. Each market has different pain points and persuasion patterns. A/B testing localized variants lets you find the winning message for each market instead of guessing.

The localize_screenshot skill can produce multiple text variants per locale -- different headline angles, benefit framings, and calls to action. Upload to App Store Connect product page experiments and let real users tell you which localized message drives the most installs.
