Hidden Door
Interactive fiction and character chat built on licensed books and films, kept on canon by design
Hidden Door is a platform for playing, and for creating, interactive stories set inside real licensed worlds rather than generic fan fiction prompts. The experiences on offer include branching interactive fiction where your choices shape the story, character chat with figures who remember earlier conversations, social games meant to be played with friends, and spinoff microdramas, comics, and audio series built from the same source material. The featured licensed worlds include Dracula, The Land of Oz, The Call of Cthulhu, Saturn's Children, Pride and Prejudice, Sherlock Holmes, and The Crow, alongside original worlds grouped under a Hidden Realms label such as Burn Rate, A Courtship of Frost, and The Tavern Door. What sets the platform apart technically is a story engine that checks each generated story beat against that world's established canon before a player ever sees it, with rights holders setting what counts as canon and what is allowed to change. Creators can build inside a world using Atlas, Hidden Door's dedicated world-building studio, or through a Creator MCP that works with Claude and other AI assistants rather than requiring a traditional game engine. Pricing is not listed on the main page beyond a mention of subscriber terms, and there is no independent Trustpilot presence to check against yet.
