FAQ

What is the difference between stories and worlds?

A world is a unique setting and cast of characters (like Dracula's castle). A world is where you play stories, which are sequential adventures within those worlds. Free users can create up to 5 worlds and play unlimited stories in each.

How does Hidden Door use AI?

Hidden Door uses a 'fractal combinatorial trope engine' where human narrative designers write flexible plot beats, and ML tools combine these with world rules, player choices, characters, and tropes to generate stories. They use LLMs for tasks like combining modifier cards or recognizing avatar components, but emphasize that human creativity drives the core story elements and art.

Can I make money by creating worlds on Hidden Door?

Yes, all creators are eligible to receive a share of platform revenue proportional to players’ engagement in their worlds. The Creator plan includes access to the Atlas world-building studio and the ability to publish worlds.

Are there parental controls or maturity settings?

The platform creates stories intended for players 13+, with content equivalent to a PG-13 movie. Worlds labeled 'Mature' contain R-rated content. Creators can adjust maturity ratings for their own worlds and apply content warnings. The system also prevents abusive or harmful content.

Do I retain the rights to the worlds I create?

Yes, you retain the rights to all intellectual property that you bring to the platform and create within your worlds.
