Hidden Door is a multiplayer AI storytelling platform that turns text-based narrative into a playable experience. Players can create characters, enter richly detailed worlds, and co-author stories in real time�either solo, with friends, or alongside AI-generated companions.
Built on a proprietary narrative engine, Hidden Door uses AI to adapt storylines, respond dynamically to player choices, and evolve characters over time. It�s not just a writing assistant�it�s an immersive storytelling ecosystem. Think of it as part choose-your-own-adventure, part collaborative novel, and part narrative game.
