i18nMate - AI-Powered JSON Translation for VS Code

Why i18nMate?

🛡️

Placeholder Protection

Automatically protects {name}, %s, {{count}}, and ICU MessageFormat syntax during translation. No more broken templates.

⚡

Batch Translation

Translate all your locale files at once — en.json → zh-CN.json, ja.json, ko.json in one click. Supports 14 languages.

📝

Consistent Terminology

Maintain a project glossary so "Submit" always becomes "提交", never "递交" or "提交出".

🔄

Smart Merge

Choose overwrite, merge, or skip — handle existing translations without losing manual edits.

📊

Progress Tracking

See translation progress in real-time with a built-in progress bar. Know exactly when it's done.

🔒

Privacy First

Only your JSON keys/values are sent for translation. No source code, no file paths, no personal data.
