Automated TTRPG Campaign Engine — The agent acts as an tireless DM: generates quest hooks, tracks NPC relationships, writes combat encounters, and produces atmospheric descriptions. No prep, no coding, just play.
AI Dungeon Master is a subscription service where the agent acts as a tireless DM for tabletop RPG campaigns. It generates quest hooks tailored to party composition, tracks NPC relationships across sessions, writes combat encounters balanced to party level, and produces atmospheric descriptions. State is maintained in Markdown/JSON files. Interface is Discord or a web chat. No coding required.
Party creation: enter character sheets (or use the quick-builder), set the genre (fantasy, sci-fi, horror, cyberpunk), and AI generates a campaign setting, main quest arc, and first session's hooks. Takes 5 minutes.
Before each session, AI generates 3 quest hook options tailored to the party's composition, level, and known NPCs. DM picks one or edits. Quests have branching paths pre-built so the AI can follow up on decisions.
AI maintains a living NPC database: name, personality, relationship to each PC, secrets, and how they've changed based on party actions. NPCs remember what happened and react consistently. "Lord Blackwood still remembers you cheated him at cards three sessions ago."
AI designs encounters balanced to party level. Runs combat with proper initiative, ability descriptions, and tactical suggestions. Handles monster stat blocks automatically. Dice rolls are real (simulated or actual dice input).
Location descriptions, NPC dialogue, and event narration generated in a consistent voice matching the campaign's tone. The AI writes the "boring" parts (travel descriptions, shop inventories) so the DM can focus on the dramatic moments.
After each session, AI generates a recap email/newsletter for absentees. "Session 7 recap: the party escaped the dungeon but Lord Blackwood's betrayal was revealed. Here's what you missed and what's coming next..."
Character art prompts (send to Midjourney), battle map descriptions (send to AI image gen), soundtrack suggestions (Spotify playlist links by mood).
