What is Hidden Door?
Hidden Door turns a prompt or a favorite book into a playable world with characters, relationships and rules that the AI keeps track of. It is made for fiction fans who want to play, create and share stories with friends.
You can start from a one-line idea such as a detective in foggy Victorian London, and the system builds a world, characters and story structure you can step into. Licensed worlds based on classic literature, such as Dracula, are also featured.
The home page describes a model that understands story structure, remembering characters and the rules of your universe. There is a Discover page for browsing worlds and a pricing page, though plan details are not shown on the home page.
