Arabic, declared by three and written right to left

Arabic is declared by CapCut, Kling AI and SceneMixer, and Vidnoz declares it on a subdomain the rule discards. Hebrew is declared by CapCut alone. No vendor publishes anything about how generated on-screen text or interface layout handles a right-to-left script. As of 2026-09-22.

Inclusion rule. Only languages declared as hreflang alternates on the host being read are listed. Coverage is not shown per language for the voice column, because the vendors that publish a list there are not the vendors that declare a site language here. Order. Vendors that declare any of these codes, in register order; then the codes no vendor declares.

1A declared alternate says nothing about script direction

Serving a page in Arabic and laying it out correctly right to left are separate jobs, and an hreflang tag is evidence of the first only. The same is true inside the product: a model asked to put Arabic text on screen faces a problem that has nothing to do with whether the settings menu is translated.

No vendor in the register publishes anything on this. The declared alternates are recorded because they can be read, and the silence on direction is recorded because that is the part a production in the region would actually want.

2Three declarations out of nine, in a set that is otherwise European

Arabic is not a token addition to any of the three lists it appears in. Three vendors independently decided the market was worth a declared language version, alongside sets that are otherwise mostly European and East Asian, and one of them declares it as ar-EG rather than as a bare code.

What that buys a buyer is a site they can read. What it does not buy is any published statement from those three about spoken Arabic, generated Arabic text, or layout. The one vendor here that does name Arabic for speech is Synthesia, whose 143-row table carries Arabic plus 13 regional variants from Bahrain to Yemen, and which declares no Arabic site alternate at all. The site column and the column a production buys on point at different companies again.

3The question to put to a vendor

Whether the model will render Arabic text legibly in a frame, and whether dialogue can be generated in it. Both are answerable by the vendor in one sentence each and neither is answered on any page this register reads.

Until one of them is, a production has a translated website and an unanswered product question, which is the pattern this whole register exists to make visible.
