Xpolyglot
Xpolyglot is a macOS app from FiveSheep that helps iOS and macOS developers localize Xcode projects and prepare apps for global App Store releases. You import Xcode projects directly, manage localization work in one place, and keep string catalogs and App Store metadata current across languages.
The app uses OpenAI to translate .xcstrings catalogs through its Magic.xcstrings feature, with delta updates that only re-translate changed strings. It also manages App Store Connect descriptions and keywords, checks length limits, and helps translate What's New text when you ship new versions.
Xpolyglot is a one-time purchase with lifetime free updates. AI translation requires your own OpenAI API key. The app is Apple notarized and built by FiveSheep, a small software company based in Estonia.
