Your Dungeon Master

“Tonight, nobody has to be the Dungeon Master. I’ll run the game. You just play.”

DungeonFlux is an AI Dungeon Master for your living room. The adventure plays on your TV, everyone plays from their own phone.

From the couch to the crypt in three steps

No books, no prep, no one stuck behind the screen. If you can open a browser, you can run a campaign.

  1. The TV title screen showing a join code over a moonlit river town

    Put the adventure on the TV

    Open DungeonFlux on the big screen. It shows a room code and waits for your party.

  2. A hero's portrait on the TV beside a phone showing species and class choices

    Everyone joins on their phone

    Players enter the code and build a hero in a couple of minutes. Each one gets a face, a name and a past.

  3. The TV during exploration: four hero portraits, the current objective, a small map and the Dungeon Master's narration over a flooded stone hall, with Explore, Talk and Search actions along the bottom

    Talk, roll and play

    Say what your hero says. The Dungeon Master answers out loud, the dice land on the TV, and the story goes where your table takes it.

The story

Characters with voices and secrets

Every innkeeper, merchant and villain speaks in a voice of their own, with a personality, a past and things they would rather not say. Charm them, haggle with them, threaten them. They remember how you treated them.

Four phone screens: a barkeep with dialogue choices, a persuasion roll that succeeds, a list of things to investigate, and a hero's character sheet with combat actions

The rules

Real SRD rules, still growing. Fair dice. Nobody fudges.

Fifth-edition fantasy rules from the System Reference Document 5.2.1, run by a rules engine on the server that draws the dice while the TV shows the roll results. The pilot supports a subset, starting with a level 1 Fighter: see what is built so far. The storyteller describes what the dice decided and never the other way round.

The look

Every scene, shot like a fantasy drama

Places, people and the things you pick up are pictured as you reach them, in a cinematic, photographic style, with music underneath. It plays like an episode your friends are starring in.

The campaign

A world that remembers

Who you met, what you promised and what you broke all stay true from one night to the next. Wander off the path and the story follows you.

On the house

$10

When the pilot opens, the first $10 of play is planned to be on us

When the early-access pilot opens, new accounts will get $10 of promotional credit after confirming an email, subject to the final terms. No card, no subscription. Bring your friends; a sponsored seat costs a player nothing.

One trial credit per account. Credit is for play on DungeonFlux and has no cash value.

After that, pay only for what you play

Top up when you want to. There is no subscription and nothing renews. Your table spends credit as the Dungeon Master talks, pictures and voices the night, and you decide how fast.

Example: your account page once sign-up opens

Picture quality

DraftStandard (chosen)Cinematic

Balance$10.00

Once sign-up opens, your account page will show the play time your balance has left at your settings, before you start. Draft pictures, fewer new scenes and narrator-only voice make it last longest.

If your balance runs out mid-session, the current moment finishes and the table pauses until you top up. Nothing you earned is lost.

Questions

What you need

  • A TV, monitor or laptop for the shared screen
  • A phone, tablet or laptop for each player
  • A modern browser and an internet connection
  • Friends. Snacks are optional.
Is an AI Dungeon Master any good?

It’s early access, so judge it on the $10 promotional credit new accounts will get when the early-access pilot opens, subject to the final terms. What we can promise: a rules engine, not the storyteller, rolls the dice and tracks the rules, so the AI can’t fudge a roll or forget your hit points. The storyteller handles the voices, the descriptions and what the world does next.

Does everyone need an account?

Everyone signs in, so your hero and your progress are saved to you. Only the people who choose to fund the table pay; invited players can join a sponsored table without adding a card.

Do we need to know the rules?

No. In a fight, your phone offers only the moves that are possible right now, and the rules engine handles the rest. The game runs a growing part of the fifth-edition System Reference Document; the supported rules page lists what is built so far.

How far does $10 go?

It depends on how you play: picture quality, how often scenes change and whether characters speak aloud. Once sign-up opens, your account page will estimate the play time left at your chosen pace, so you will know before you start. We will publish typical costs per session once early access gives us real numbers.

What happens when the credit runs out?

The moment in progress finishes, then the table pauses with a prompt to top up. Your campaign, your heroes and everything that happened are saved.

Can a bad roll ruin the night?

Bad rolls have real consequences, because that is what makes good rolls matter. The story always offers a way forward, and the narration can never change a result the dice decided.

What happens to what we say and type?

What your table says and types is sent to the AI services that run the story, the voices and the pictures, so they can answer you. Our privacy policy draft will name those services before launch.

Is this official Dungeons & Dragons?

No. DungeonFlux uses the System Reference Document 5.2.1 under its Creative Commons licence and is not affiliated with or endorsed by Wizards of the Coast.
