About ZenMulti

ZenMulti is an AI tool for developers that helps automate the complex process of application internationalization without manual copy-pasting. It functions as a native extension within the Visual Studio Code environment to bridge the gap between resource files and global accessibility.

The tool specifically targets developer workflows by automating the translation of JSON and Java .properties resource files. By integrating your personal OpenAI API key, ZenMulti leverages GPT-4o or GPT-3.5 models to provide context-aware translations that respect code structure and key-value pairs. This local-first approach ensures that your translation data moves directly between your workspace and OpenAI, maintaining high efficiency for large-scale projects.
