Now you can enjoy crazy AI powered adventures with your friends.
Play it here.


AI Dungeon was partially inspired by Dungeons and Dragons when I realized that there were no games available that gave you the same freedom to do anything that I found in DnD. AI Dungeon makes unlimited freedom possible by using powerful natural language generation models like GPT-2 to decide what happens in a story no matter how crazy your action is.

But one of the other best parts of DnD is the ability to play with your friends and share your zany experiences together so that was naturally the next step in the evolution of AI Dungeon.

How it works

Multiplayer (Alpha) AI Dungeon works very similar to normal single player, but with a few differences.

  • Players alternate taking turns doing actions with the AI generating a result after each action.
  • You can play with both local (pass-n-play) and online friends.
  • Actions and stories are now all in third person rather than second person.
  • The host of a multiplayer game can act like a dungeon master and supervise the AI, modifying and fixing responses it gives.

Because the format for multiplayer is different from the original training data the model will initially not be quite as good as single player, however as hosts supervise the AI, fixing issues and improving on it’s responses, we’ll be able to use that data to train and improve the multiplayer model. This alpha version of multiplayer is just the beginning.

How to play

Right now hosting a multiplayer game is only available to people who subscribe at $4.99 a month and become AI Dungeon supporters. However anyone can join a multiplayer game that a supporter hosts.

Becoming a supporter also unlocks other awesome perks including audio narration of stories, changing advanced settings like temperature (randomness) and generation length, and first access to new features as they come out.

But most of all supporters are visionaries who see the potential of AI in games and enable us to continue building and innovating on how to create entirely new types of games with AI.


A big part of our vision is to use AI to power vast, living game worlds where your actions leave lasting effects on the world.

Imagine a game where every NPC is unique and interacts realistically to what you do and lives out their own life. What if you could form a musical band of orcs that performs and promotes human-orc equality throughout the kingdom and actually change how the kingdom’s people view each other. Or if you could go on a quest with other characters, come back to the town, and discover that the mayor NPC has decided of his own volition to become a necromancer and has turned the residents to undead.

Although these goals may seem ambitious and we still have a long way to go, there is vast untapped potential for AI powered games and AI Dungeon is leading the way in starting to unlock those possibilities.

We are entering a new era of gaming.
