What is Xpolyglot?
Xpolyglot is a macOS app from FiveSheep for localizing Xcode projects and helping developers prepare apps for global release. It is positioned as an AI-powered localization workflow tool rather than a general translation service, with a focus on Apple app development and App Store readiness.
The core workflow centers on importing Xcode projects, managing multiple localization projects in one place, and translating string catalogs such as Magic.xcstrings. The website emphasizes that the tool fits into an existing development process with a few clicks, so developers can keep translations organized without moving between separate tools.
A major feature is delta updates, which detects changed strings and translates only what changed. That is meant to save time and reduce translation cost, especially for apps that update frequently.
Beyond string translation, Xpolyglot also manages App Store Connect metadata such as descriptions and keywords across languages, and it supports translating new app versions and release notes. It is aimed at iOS/macOS developers, indie developers, and small teams that want faster multilingual publishing with less manual overhead.
