What you are allowed to feed in
Most entries in this register regulate what comes out. Four of the seventeen vendors also regulate what goes in: a refusal of real photographs as character references, two consent rules about the likeness of another person, and one condition about copyright in uploaded material. As of 2026-09-12.
| Vendor | What is published | Detail |
|---|---|---|
| Refusal of a category | SceneMixer | Real photographs refused as character references |
| Permission from the person | Higgsfield | No image of another person without their permission |
| Consent, with an age condition | Synthesia | Free, informed consent for a custom avatar |
| A condition on the output grant | HeyGen | Uploads must avoid copyright violations |
| Defined use boundary | LTX Studio | Personal use excludes promoting a business |
Inclusion rule. Restrictions published on vendor pages. A restriction enforced in the product without being published is not recorded. Order. Refusal first, then the consent rules, then the condition attached to a grant, then the use boundary.
1Likeness risk enters on the input side
Most exposure in generated advertising comes from what was supplied, not from what was produced: a photograph of a person, a recognisable face, a voice. A vendor refusing photographs as character references removes a category of that exposure before anything is generated.
It also removes a capability. Generating a recognisable spokesperson from a photograph is something some campaigns want, and this vendor's pages say it will not do it.
2A published boundary is worth as much as a published permission
Knowing what a tool refuses tells a brand which conversations not to start. It is the same kind of information as a licence line and it appears far less often, which is why this register records it separately rather than folding it into a notes column.
Four of the seventeen entries publish an input restriction of any kind, so the table above is short and its shortness is the finding.
3The nearest thing elsewhere is a use definition
One other vendor defines what its personal use licence rules out. That regulates the use rather than the input, which is why it sits in the last row of the table rather than among the input rules.
Five published boundaries across seventeen vendors is the state of this field as it can be read today, and three of the five arrived in the second batch of readings rather than the first.
