AI Game Master (AI GM/DM): Definition & Explanation
An AI Game Master (Dungeon Master) uses an LLM to play the GM/DM role in a tabletop RPG (TRPG). When a player declares an action in free text, the AI describes the situation, voices NPCs, and returns the outcome as a story. Tools range from rules-based ones that process dice rolls and combat per systems like D&D 5e (Friends & Fables) to rules-free, completely free-form storytellers (AI Dungeon). The biggest appeal is needing no scheduling with friends or GM prep—adventure solo, anytime, 24/7. The flip side of high immersion: remember AI responses are fiction, not fact, watch for over-long sessions, and note that content filters exist.
