How AI is used
Hidden Door is an online roleplaying platform where human-written plot beats are combined with machine learning tools and LLMs to generate narratives. The system allows players to make choices that shape the story, supported by a light stats system and dice rolling for challenging actions.
The platform is designed for professional creatives, such as authors and filmmakers, who have existing fanbases and want to let their audience interact with their stories. It also serves players who enjoy roleplaying and fan fiction.
Creators can collaborate with the platform to define how characters enter a world, which original characters are available, and the writing style. The platform includes a card collection system where players gather characters, places, and modifiers to use in future stories.
Buyers and creators should note that self-serve world creation is not currently available; the platform seeks authors with public works and existing online fanbases for partnerships.
