Which declared sets contain one another exactly
Four declared site lists in this register form a single chain: two codes inside five, five inside nine, nine inside thirteen, with nothing dropped at any step. The other five sets do not nest. As of 2026-09-12.
| Tool | What is published | Detail |
|---|---|---|
| D-ID | de, en | Contained in all three sets below |
| Higgsfield | de, en, es, ja, ko | Contains the two above, sits inside the two below |
| Vidu | de, en, es, fr, ja, ko, pt, ru, zh | Contains the five above |
| PixVerse | The nine above plus id, th, tr, vi | Contains all three sets above |
| Runway | en, fr, ja, ko, pt-BR | Nests inside nothing, and skips German |
Inclusion rule. Declared same-host sets that are subsets of one another, plus the one comparable set that is not. Sets discarded by the counting rule are excluded. Order. Shortest set first, then the non-nesting set last.
1Containment says more than a total
Two sets overlapping is unremarkable. Four sets nesting exactly, across companies of very different sizes, is evidence about sequencing: the field agrees on which languages get translated first and differs only on how far to go.
A ranked column of totals would show four numbers between two and thirteen and would hide the fact that they describe one ordering at four depths.
2The set that breaks the pattern
One five-code set declares English, French, Japanese, Korean and Brazilian Portuguese, and no German. Since eight of the nine declared sets include German, including a set of two codes, that is the most conspicuous omission in the column.
It is also the only mixed-form set here, with one region-tagged code among four bare ones. So the vendor that broke the sequence is also the one that named a market rather than a language.
3What the chain predicts and what it does not
It predicts which languages a vendor entering a new market will add next, and it is a reasonable guide to where the field believes its buyers are. It predicts nothing at all about voices or generated documents.
Three of the four vendors in the chain publish nothing in either output column. The fourth publishes a spoken-language claim with no list behind it, so the chain is entirely a fact about marketing pages.
4The three columns behind this question
| Column | How many of the 18 tools name a list |
|---|---|
| Dialogue language | 5 of 18 tools |
| Document language | 1 of 18 tools |
| Site language | 9 of 18 tools |
Inclusion rule. The three columns this register keeps. A column stays listed even when no vendor names a list, because silence in a column is itself recorded. Order. Alphabetical by column name.
