About this skill

About UX copy localizer

Translated interfaces often read awkwardly and break layouts because strings get longer. This skill translates UI strings for meaning and tone rather than word for word, keeps placeholders and formatting intact, flags strings that exceed your length limits with shorter options, and notes cultural issues such as formality, dates, numbers and currency. It marks strings that need review by a native speaker, which it recommends before any release. To use it, paste the skill into your assistant and send your UI strings (with keys and character limits) and the target languages; the reply is laid out as “String table: key, source, translation, length, fits?”, “Cultural notes” and “Strings needing native review”.
