A universe is a rulebook for your videos. It tells the AI how to write scripts and draw scenes so every episode feels like the same show.
Universes get easier when you separate these two ideas.
Prompt (your story idea)
What happens in this one video.
Universe rules (the show)
Who is talking, how the story is told, and how it looks.
Script rules
Voice, story shape, and what must happen.
Visual rules
Style, characters, and what to avoid.
Default settings
Format, voice, music, and captions.
In the universe editor, script rules go in Script & General Guidelines, and visual rules go in Visual & Scenic Guidelines.
When you click Create Universe, our AI drafts a starting point for you:
Best practice: Treat this as a first draft. Most of the time, you should delete most of it and rewrite it in your own words.
These are production universes. Each page explains why the rules exist, then shows a full rulebook you can copy and tweak.
