Hidden Door AI
AI-driven interactive storytelling platform for collaborative role-play.
About Hidden Door AI
Hidden Door is an interactive storytelling platform that blends tabletop-style role-play with fan fiction. Players create a character and step into a narrative guided by an AI-driven 'Narrator,' responding to prompts that steer the plot in different directions; each playthrough differs because choices genuinely change the story. The underlying story engine was built by combining AI trained on public domain fiction with manual authoring work, letting it mix story forms, characters, and situations into new adventures. Completing a story unlocks cards that can be carried into other adventures, and players can apply 'World Modifiers' to change the tone or direction of a session. Writers and game designers can build their own playable worlds in as little as 30 minutes and publish them for others to play, with a creator revenue-sharing model that pays authors when their worlds are used. The company was co-founded by CEO Hilary Mason and chief product officer Matt Brandwein. Hidden Door is aimed at casual players who enjoy collaborative storytelling as well as writers and worldbuilders who want to turn their fiction into playable experiences. The product is still in early access, and pricing has not been published.
