An AI dungeon master for your group
Every tabletop group knows the problem: everyone wants to play, nobody wants to run the game. A good DM spends hours on prep. AI Dungeon Master hands that seat to an AI. It sets the scene, reacts to whatever your party does and keeps the story moving, while you and your friends decide what the heroes actually do.
Every adventure opens in a fantasy world: the AI greets your party by their nicknames and describes the first scene in a few sentences. From there the story goes wherever you push it — a grim dungeon crawl, a murder mystery, or a heist to steal a goblin accountant’s abacus. No rulebooks, character sheets or dice required.
How a game works
- The host creates a room. You need at least two seats filled to start; the second can be a bot.
- The AI writes the opening and offers 2–3 choices as buttons.
- Anyone can tap a choice or type their own action (up to 120 characters) and send it with “Ask the storyteller”.
- Each round takes exactly one move: the first player to act decides for the whole party, and that part of the story is tagged with their name.
- The AI continues the story from that move and offers new choices; the next round starts 3 seconds later.
- Each round has a 60-second timer. If nobody acts, the game picks the first choice so the story never stalls.
- After round 10 the game ends. Every move that made it into the story is worth 1 point, and the top scorer is crowned champion.

Click Create, pick a nickname, and your room is live. Share the link or the 4-character room code (letters and digits); friends open the site on a phone or laptop, type a name and land in the lobby. No account, no download, any modern browser. It is the quickest way to get an AI dungeon master online for a Discord game night.
- Party size: up to 10 per room; 2–5 is the sweet spot.
- Bots: the “🤖 Bot” button fills a seat so you can start. Bots never take turns, so one bot means a solo adventure with the AI.
- Dropped connection: come back to the room and the story and timer reload.
- Rematch: after the finale the host hits Rematch and the AI starts a brand-new adventure.
- House rules: the host can kick a disruptive player. A room with no activity closes after 10 minutes.
What you can and can’t change
There are no lobby options: 10 rounds, 60 seconds each, a fantasy opening and AI-generated scenes. Genre and tone come from your moves: file paperwork at the castle for three rounds and the narrator leans into bureaucratic comedy.
To set expectations: this is not a full tabletop system. There are no d20 rolls, hit points, ability scores or inventory. The side panel shows the player count, ❤️ heroes in the party, 📍 the current location when the AI names one, and the round number. Think one-shot, not campaign: a story can’t be continued next week, and a rematch begins a fresh one.
Tips for a better story
- Be specific. “Throw the torch into the oil barrel” gives the AI something to work with; “do something cool” doesn’t.
- Agree on turn order. The fastest tap wins the round, so without a house rule one person plays the whole game. Rotate down the player list.
- Skip the buttons sometimes. The AI’s choices are prompts, not a menu. The best twists come from typed actions: bribe the dragon, run for mayor, adopt the goose.
- Keep a shared tone. The narrator reads the whole story so far, so a dark campaign only stays dark if everyone writes that way.
- Watch the clock. The timer turns red in the last 10 seconds; stay silent and the game picks choice one for you.
