About This Game

An Adventure Only Limited By Your Imagination.

The most popular AI text-based adventure is coming to Steam! AI Dungeon is a text-based, AI-generated fantasy simulation with infinite possibilities. Unlike most games where you experience worlds created by game designers, with AI Dungeon, you can direct the AI to create worlds, characters, and scenarios for your character to interact with. You could lead an army fighting back an alien invasion, be a mythical detective investigating the attempted assassination of the fairy queen, or simply enjoy the pleasures of a simple slice-of-life scenario.

Unlimited AI

In this Steam release, AI Dungeon is offering its first ever one-time purchase for an unlimited AI experience. On web and mobile versions, free play is governed by an energy system. In this exclusive Steam-only offering, you can play forever without worrying about energy limits.

Create Worlds

Pick a character, a world, and a story. The AI will fill in the details for your unique adventure. Or choose predefined worlds from other users, or a random one using our quick start!

Take Actions

You can decide what your character says or does. The AI will produce responses from other characters, or world events for you to respond to. Every adventure is unique and unexpected.

Make It Yours

Save the scenario for later. Don’t like the AI generated text? Initiate a re-do or enter your own words. You are the main character AND director of the adventure.

Reviews

“Unlike a classic text adventure like Zork — where players quickly become familiar with “you can’t do that”-style messages when they type something the designers hadn’t planned for — AI Dungeon can respond to any command. For example, when my brave knight was charging into battle, I typed “get depressed” and he quickly sat on a rock with his head between his hands.”

“AI Dungeon is like doing improv with a partner who is equal parts enthusiastic and drunk.”
