Prepare Your App for Translation with Crowdin’s i18n-setup AI Skill

Your product can be ready for production without being ready for translation. In this walkthrough, I use Crowdin’s i18n-setup skill with Claude Code to prepare a sample application for localization, connect it to Crowdin, and test Chinese translations in the running app. You’ll see how the agent detects the existing setup, creates a plan, tracks progress, and configures Lingui library. The agent then marks translatable strings so Lingui can extract them into PO files. We also look at AI-generated context for translators, glossary suggestions, and GitHub synchronization setup.
