How to Translate UI Text with Copilot

Translate locale files in your project with Copilot and ToolRouter. UI localization in your editor.

Copilot brings translation directly into your i18n workflow, treating localization as a code task rather than an external handoff. Translate locale files, UI strings, and documentation without leaving your editor, then review the changes in your diff view alongside the rest of your code. This is ideal for developers who maintain localization as part of the build process, ensuring that new features ship with translations rather than accumulating a backlog of untranslated strings that need a separate localization pass.
