BoxBuilder currently does not integrate smoothly with external translation apps like Translate & Adapt. The good news, though, is that our development team is already looking into this for future updates. We're committed to making BoxBuilder even more versatile and user-friendly.
While we work on improving compatibility with third-party apps, you can still make use of our built-in translation feature. Keep in mind that this built-in feature has some limitations – it may not cover every part of the builder, but it's a helpful option to get you started.
