How to Use Hidden Door in 2026: Step-by-Step Guide
Hidden Door is an AI-powered narrative adventure game where an AI dungeon master runs immersive, branching stories in real time. Based on licensed IP or original worlds, your choices drive the narrative — the AI generates coherent, surprising story beats that respond to anything you do.
Hidden Door brings the collaborative, improvisational nature of tabletop RPG dungeon mastering to a digital platform — an AI that can improvise endlessly in response to player choices.
The AI Dungeon Master
Hidden Door's AI serves as narrator, character voice actor, and game master simultaneously:
- Describes scenes and environments in rich detail
- Plays non-player characters with consistent personalities
- Tracks story state, character relationships, and world lore across sessions
- Generates new story beats that logically follow from your choices
Unlike scripted narrative games with branching dialogue trees, Hidden Door's AI can respond to anything you type — try something unexpected and the AI incorporates it into the narrative rather than hitting a dead end.
Licensed Worlds
Hidden Door has licensed IP partnerships to create adventures set in established fictional universes. Players can explore stories in familiar settings with canonical characters, while the AI maintains consistency with the source material's tone and lore.
Multiplayer
Hidden Door supports multiplayer sessions where multiple players collectively drive the story. The AI dungeon master manages all players' inputs simultaneously, maintaining narrative coherence across concurrent character actions.
Session Continuity
Adventures persist across sessions — the AI remembers where your story left off, character relationships developed, choices made, and consequences unresolved. Return to an active story and pick up mid-narrative.
Target Audience
Hidden Door targets tabletop RPG players who want the experience of a DM-run campaign without the scheduling overhead of gathering a group. It also appeals to collaborative fiction writers and interactive story enthusiasts.
Funding and Team
Hidden Door raised $12M in Series A funding (2022). The founding team includes AI researchers and game designers with backgrounds at Pixar, Disney, and major game studios.

Pro Tips
- Be specific: The more context you provide, the better the response. Instead of "write an email," try "write a professional follow-up email to a client who hasn't responded in two weeks."
- Iterate: If you don't get what you need, ask for clarification or refinement: "Make it shorter" or "Use a more formal tone."
- Use examples: Show Hidden Door what format you want by including an example in your prompt.
- Save useful conversations: Most platforms let you name and revisit conversations — organize by project or topic.
