I18n Studio
FreeMac app that translates app localization files with GPT
What is I18n Studio?
I18n Studio is a macOS app for developers that translates localization files such as JSON, XML, Localizable.strings and String Catalogs. It uses context you supply so the wording fits your app, and runs on your own OpenAI API key.
You load files for several languages, then translate a single value, a key, a whole language or everything at once, and write the results back to the files. Comments can give context, mark text that must not be translated, or describe the scene where a string appears.
It is meant to fit Xcode, VS Code and Android Studio projects, covering iOS, Android and JavaScript apps. Because it uses your own key, translation costs are billed by the model provider.
