AI Dungeon

AI Dungeon platform architecture and interactive narrative engine

AI Dungeon (accessible at aidungeon.com and mobile iOS/Android apps, developed by Latitude, created by Nick Walton) is the pioneering generative artificial intelligence text adventure platform, infinite roleplaying game, and interactive storytelling workspace. Built to grant players complete creative freedom, AI Dungeon dynamically authors open-ended narratives in response to any natural language action or dialogue.

The platform is anchored by large multimodal language models with context memory windows scaling up to 32,000 tokens. AI Dungeon features Core Action Modes (Do, Say, Story, See), customizable Memory & Story Cards (anchoring lore, character traits, and inventory), multiplayer roleplay adventures, AI image illustration, and community scenario sharing.

Core storytelling capabilities and roleplay tools

AI Dungeon delivers features for immersive interactive fiction and table-top roleplay:

• Open-ended text adventure engine: Direct any action, speak any dialogue, or describe any event; the AI adapts the narrative instantly.
• Core action inputs: Choose between Do (perform physical action), Say (speak aloud), Story (narrate background events), or See (generate visual scene illustrations).
• Memory & Story Cards lore system: Define factions, magic systems, character backstories, and world locations that the AI references consistently.
• Multi-model selection: Toggle between fine-tuned storytelling LLMs (Mixtral, Claude, Llama) with expanded context windows.
• Multiplayer campaign mode: Create shared interactive adventures with friends in collaborative turn-based campaigns.
• Community scenario library: Browse thousands of pre-authored scenarios across fantasy, cyberpunk, sci-fi, horror, and mystery.
