The six tools that declare nothing
Six tools declare no same-domain language alternates and publish no output or voice language list: Hailuo, invideo AI, LTX Studio, Pika, Runway and Vidu. That is the majority position in this register. As of 2026-09-12.
| Tool | What is published | Detail |
|---|---|---|
| Hailuo | None declared | hailuoai.video |
| invideo AI | None declared | invideo.io |
| LTX Studio | None declared | ltx.io |
| Pika | None declared | pika.art |
| Runway | None declared | runway.com |
| Vidu | None declared | vidu.com |
Inclusion rule. Tools with a public English site selling AI video generation, read for hreflang alternates on their own domain and for any published language list. Order. Alphabetical by tool name.
1English-only is a coherent strategy, not an oversight
Six vendors shipping in one language is not six mistakes. It is a market position: sell to English-speaking buyers, let everyone else use the product in English, and spend the effort elsewhere. Several of these are API-first products where the buyer is a developer and the interface language matters much less.
The register records the absence without calling it a gap. What it is for a given reader depends entirely on who that reader is selling to.
2Silence in the voice column has a different weight
No site alternates tells you about a marketing decision. No published voice languages tells you that a production planning a non-English series has nothing to plan against, which is a harder problem than a menu in the wrong language.
All six are silent in both. For the site column that is a choice; for the voice column it may simply mean the capability is not framed that way in their documentation, and this register cannot distinguish those two from published pages.
3Why six rows that all say the same thing are still six rows
Merging them into one line reading six tools publish nothing would be shorter and would stop a reader checking any individual vendor. Each row carries its own domain and its own check date, and each can change independently.
The first of them to publish a list moves off this page and onto the register with a populated cell, which is the outcome this page exists to make visible.
4The three columns behind this question
| Column | How many of the two tools publish a list |
|---|---|
| Dialogue language | 1 of 2 tools |
| Document language | 1 of 2 tools |
| Site language | 2 of 2 tools |
Inclusion rule. The three columns this register keeps. A column stays listed even when neither tool names a list, because silence in a column is itself recorded. Order. Alphabetical by column name.
