AI Localizer is a developer-tool software solution that helps iOS and macOS developers automatically localize their Xcode projects into multiple languages. It enables direct translation of app string resources and catalog files, making it suitable for app-localization workflows where efficiency, accuracy, and developer control are required. This product is designed for individual developers as well as teams working on apps built with Xcode. It supports projects developed with SwiftUI, Storyboard, or XIB, and can handle both .strings and .xcstrings formats. Typical use cases include adding new languages to an existing app, editing and refining localized text, exporting translations for proofreading, and helping developers reach a global audience without extensive manual translation work. Key features and capabilities include: - Automatic discovery of all localizable text resources in an Xcode project and direct saving of translated content back into the project. - Choice of translation engine: use the built-in AI translation or configure a custom Microsoft Azure or Google Translate account. - Support for over 35 languages, including Arabic, Chinese, Japanese, English, Spanish and French. - Compatibility with SwiftUI, Storyboards, and XIBs, supporting both .strings and .xcstrings file formats for modern and legacy app interfaces. - Proofreading and quality-control workflow, allowing export of translated strings to CSV for review and re-import after corrections. - Local processing on the Mac to ensure data privacy and prevent unnecessary transfer of project files to external servers. AI Localizer provides a focused, integrated solution for developers who want to streamline app localization while maintaining control over translation quality and workflow. It reduces the manual effort required to prepare multilingual app versions, helping teams release globalized software faster and more efficiently.
