asc-localize-metadata

Automate App Store localization by using LLM translation to translate descriptions, keywords, subtitles, and names, then synchronizing the metadata directly to App Store Connect via the asc CLI. This handles bulk translations for global markets efficiently.

You can translate App Store metadata fields including app descriptions, keywords, what's new notes, subtitles, and names. This covers both per-release version localizations and persistent app-level app-info localizations.

Yes, you need App Store Connect authentication and knowledge of your specific app and version IDs. These identifiers are required to target the correct listing and synchronize the translated metadata back to the correct version.

Yes, you can translate what's new release notes for different locales. The process downloads existing release notes, translates them using LLMs, and uploads the localized versions to App Store Connect for your target markets.

The best way to synchronize localized App Store metadata is downloading existing listing text, translating it with LLMs, and uploading the localized versions directly to App Store Connect using the asc CLI for automated synchronization.

Limitations include requiring specific app and version IDs for targeting, and the process depends on App Store Connect authentication. You must ensure your LLM translations fit App Store character limits for subtitles and keywords before uploading.
