DM Engine is a full AI Dungeon Master for D&D 5e — not just a chatbot, but a structured game master that builds scenes, runs combat, tracks your campaign, and delivers a cinematic tabletop experience without needing a human DM. NEW: PLAY WITH FRIENDS Host a party of up to four. Share a join code, and your friends drop into the same living story — no scheduling, no human DM, no one left waiting. Everyone acts in their own turn, rolls their own dice, and fights in the same initiative order. One Guild subscription hosts the whole table; joining is free. WHAT IT DOES Generates opening scenes, NPC dialogue, and story beats Runs full D&D 5e combat — initiative, HP, conditions, death saves Handles skill checks, saving throws, and attack rolls with real dice Remembers everything across sessions — decisions, deaths, relationships Builds a living world that reacts to your choices DEATH MEANS SOMETHING Drop to zero and you're rolling death saves — flat d20, three failures and that character's story ends. Permanently. No resurrection, no undo. Create a new character and the DM writes them into the story at the next turn of the road. CAST LIKE A SPELLCASTER Open your spellbook mid-fight, pick your targets, watch your slots. Attack rolls against real AC. Inspiration to reroll when the dice betray you. Long rests restore you — if the story lets you rest. CAMPAIGN SETUP Choose your world setting, tone (heroic, dark, horror, comedy), and ruleset. Load a lore pack — Forgotten Realms, Ravenloft, Eberron, or the Nine Hells of Avernus. Create your character with class, race, background, and backstory. The DM weaves your history into everything. THE DM VOICE Built on Claude, one of the most capable AI models available. The DM narrates like an author — specific, present-tense, cinematic. No "adventure awaits." No breaking character. Real consequences for every action. FULL SESSION MEMORY The app tracks your campaign across sessions using a compression system that distills key events into permanent facts. The DM remembers who you killed, what you promised, and what you broke. SESSION RECAP Auto-generated summary after every session. XP log, key moments, loot, and decisions. Your campaign history builds over time. Built on the D&D 5e SRD 5.1 under Creative Commons Attribution 4.0. Not affiliated with Wizards of the Coast.
