How It Works

Simply push your code to GitHub, and we'll open a PR with accurate localizations powered by AI whenever you add or modify your string catalog.

Connect to GitHub

Link your repository, select a branch, and we'll automatically detect new strings, organize them, and prepare them for seamless localization.

Automatic Localization

As you push new strings, our AI translates them into up to 40 languages automatically. Add or update languages with just a few clicks.

Review and Merge

Stay updated with automated pull requests. Each time a string is added or updated, we create a pull request for you to review and merge.
