I18n

I18n is a macOS developer tool that streamlines the localization of applications by leveraging GPT-4 for high-quality, context-aware translations. It is designed to work directly with common resource formats such as JSON, XML, Localizable.strings, and String Catalogs, reducing manual effort and errors in internationalization workflows. The primary purpose of I18n is to help developers and localization teams manage, translate, and maintain language resources efficiently within their existing development environment.

The tool analyzes keys, values, and surrounding context to produce translations that are semantically accurate rather than literal. It supports batch processing of files, making it possible to localize large projects quickly while preserving structure and formatting. I18n also helps identify missing or inconsistent translations across languages and can align terminology to maintain a consistent voice across the product. Integration with macOS allows for a native experience, including file system access, drag-and-drop support, and smooth handling of large localization files.
