Introduction
What Babelize is, who it's for, and how it works.
Babelize is an AI-powered localization platform that translates your React and Next.js applications into 40+ languages. Connect your GitHub repo, select target languages, and handle the rest — extracting strings, translating them, and raising a PR with production-ready resource bundles — fully automated.
Built for React and Next.js
Handle one-time full translations, incremental syncs on every push, and team reviews — all without leaving your development workflow. Babelize supports React, Next.js, TypeScript, and any framework that uses standard i18n resource files.
