Xpolyglot is a macOS application developed by FiveSheep designed to facilitate the localization of Xcode projects, aiming to streamline App Store submissions and broaden the accessibility of applications on a global scale.

It is notable for its seamless integration into the standard development workflow, allowing developers to easily import their Xcode projects and manage various localization projects in a single place.

Xpolyglot uses Artificial Intelligence technology to assist in the localization of application string catalogues, providing a cost-effective alternative to professional translators.

The unique feature of Xpolyglot is its usage of delta updates to detect any changes in the strings and translate only those that have been modified, which results in much efficiency in time and resource management.

Xpolyglot also caters to a broader aspect of app development by providing metadata management and global description and keyword updates across all supported languages, ensuring that apps are optimized for discoverability in the global market.

Lastly, it simplifies version management, enabling developers to easily create and translate new versions in the target languages. Xpolyglot requires a separate OpenAI API key for operational purposes.

Please note that Xpolyglot is notarized by Apple, signifying that it is safe to use and free from malware.
