# `PhoenixKitCatalogue.AITranslateBinding`
[🔗](https://github.com/BeamLabEU/phoenix_kit_catalogue/blob/0.8.0/lib/phoenix_kit_catalogue/ai_translate_binding.ex#L1)

`PhoenixKitAI.Components.AITranslate.FormBinding` for catalogue forms —
the storage-specific half of the shared AI-translate glue.

Catalogue stores translations in the multilang `data` JSONB via
`PhoenixKit.Utils.Multilang`, with per-language overrides under
**underscore-prefixed** keys (`data[lang]["_name"]`). The engine speaks
plain field names, so `apply_translation/4` re-prefixes before writing and
force-stores even values equal to the primary (so an untranslatable string
still fills the field instead of looking like a failed translation).
