Xpolyglot

Xpolyglot is a macOS application designed specifically for Apple developers who need to localize their apps for international markets. It works directly with Xcode projects to translate string catalogs and manage App Store Connect metadata across multiple languages. The tool integrates AI translation through OpenAI's API, which developers must provide separately, to automatically generate localized content at a fraction of the cost of human translators.

What sets Xpolyglot apart is its focused approach to the Apple developer ecosystem. It detects changed strings and only translates what's new, saving both time and money. The tool also validates App Store descriptions and keywords for length and relevance, ensuring compliance with platform requirements. It's notarized by Apple, meaning it's been verified as malware-free and safe to run on macOS.

This tool is ideal for indie developers and development teams looking to expand their app's reach without the high cost of professional translation services. It handles the tedious work of managing multiple language versions, from interface strings to store metadata, making global app distribution more accessible. The cost comparison shows potential savings of over 90% compared to traditional human translation services.
