How do I add languages to my card?

In the editor's Content tab, in the languages bar above the sections list, add a language and the AI translates all content in one click, right in the editor with no chat involved (there is a stop button, and the per-language markers show what is missing or outdated). When several languages are waiting, a "Translate all" button runs them all in one click, and clicking the amber counter next to a language opens the list of sections still waiting, with a direct jump to editing each one. Next to any single untranslated field there is also a "Translate with AI" button that translates just that field. Multiple languages are available on every paid plan; on the free plan the card has one language. A multilingual card opens in its primary language, and a ?lang= link opens in a specific language.
