# LocalePack

> LocalePack (https://localepack.app) is a format-aware AI localization service for browser extensions and JSON locale files. Upload your messages.json, choose languages, and download a ready-to-ship _locales ZIP — placeholder-safe, format-compliant translations into 52 languages. No subscription, no TMS setup: pay once per translation order (from $9.99).

LocalePack preserves placeholders, plurals, and file structure across all locales, and works for Chrome, Firefox, Edge, Safari, and Opera extensions as well as Next.js, i18next, react-i18next, React Native, and Vue apps. Chrome Web Store listing translation is also supported.
