AI Dungeon

Generates contextually-aware story continuations based on player actions and previous narrative state, using a language model backend that maintains story coherence across multiple turns. The system tracks narrative context (character state, world state, plot progression) and feeds it to the LLM along with the player's action to produce the next story segment. This enables branching narratives where player choices meaningfully alter the story direction while maintaining internal consistency.

Allows players to define custom characters with specific traits, backgrounds, and personality attributes that are encoded into the narrative context and passed to the LLM on each turn. The system maintains a character profile (stored server-side) that includes descriptive attributes, goals, and relationships, which are injected into the story prompt to ensure the AI responds in character. This creates consistent character behavior across multiple story sessions and enables the AI to make decisions aligned with established personality.

Filters generated narrative content to prevent inappropriate, explicit, or harmful material from appearing in stories. The system likely uses content moderation APIs or trained classifiers to detect and remove or regenerate problematic content (violence, sexual content, hate speech, etc.). This operates on both generated narrative and player input, ensuring the platform maintains community standards while allowing creative storytelling.

Provides templated world-building tools and pre-authored scenario frameworks that players can customize to establish the setting, rules, and initial conditions for their story. The system includes genre-specific templates (fantasy, sci-fi, modern, horror) with editable world parameters (magic system, technology level, factions, geography) that are encoded into the narrative context. These world parameters act as constraints on the LLM's generation, ensuring story events remain consistent with the established world rules.

Maintains a rolling context window of previous story segments and player actions, summarizing or truncating older narrative history to fit within the LLM's token limits while preserving essential plot points and character state. The system uses a context management strategy (likely summarization or selective truncation) to keep recent story details available to the LLM while preventing context overflow. This enables long-form stories (50+ turns) without losing narrative continuity, though with potential degradation in recall of very early story events.

Interprets natural language player actions (e.g., 'I sneak into the castle') and translates them into narrative outcomes by feeding the action description to the LLM along with current story state. The system does not use a rigid action parser or pre-defined action trees; instead, it relies on the LLM to understand player intent and generate plausible story consequences. This enables creative, unexpected outcomes where player actions can succeed, fail, or have unintended consequences based on narrative logic rather than game mechanics.

Applies genre-specific prompting and tone parameters (fantasy, sci-fi, horror, romance, etc.) to guide the LLM's narrative generation style, vocabulary, and thematic focus. The system likely uses genre-specific system prompts or fine-tuned model variants that emphasize appropriate narrative conventions (e.g., epic language for fantasy, technical jargon for sci-fi, suspenseful pacing for horror). This ensures generated stories maintain consistent tone and genre conventions without requiring manual style guidance from players.

Stores complete story history (all narrative segments and player actions) server-side with the ability to save story snapshots and load previous story states to explore alternative branches. Players can save at any point and later load a previous save to make different choices, creating a branching story tree. The system maintains separate story branches in the database, allowing players to explore multiple narrative paths from the same decision point without losing previous branches.

Enables multiple players to contribute actions to a shared story in turn-based or real-time fashion, with the LLM generating narrative continuations based on player actions from any participant. The system manages player turns, action queuing, and narrative coherence across multiple contributors. This allows collaborative fiction creation where players build a story together, with the AI mediating between player actions and generating unified narrative outcomes.

Generates dynamic NPC dialogue and behavior based on character personality, story context, and player interaction history. The system treats NPCs as LLM-driven agents with persistent personality traits and goals, generating contextually appropriate responses to player actions. NPCs can initiate dialogue, react emotionally to player choices, and develop relationships with the player character based on interaction history, creating the illusion of autonomous characters rather than static dialogue trees.

Adjusts narrative challenge, obstacle difficulty, and story pacing based on player performance and engagement signals. The system may track player success rates, story progression speed, and engagement metrics to dynamically adjust the difficulty of challenges the AI presents. This could involve making obstacles easier if the player is struggling, introducing new challenges if the player is bored, or adjusting pacing to match player engagement levels.
