AI Dungeon is a pure-text interactive storytelling game powered by artificial intelligence (such as GPT models). It’s an AI-native game where players interact with the AI using natural language commands to collaboratively advance an open, dynamic storyline with no preset scripts and a high degree of freedom.
It supports web-based online play for free, and also offers Android and iOS mobile apps, with a PC version released on Steam for a cross-platform experience.
The base version is free to play online; you can access core AI storytelling features via the official website or app stores.
At the start, you can choose from multiple preset worldviews such as fantasy, cyberpunk, zombies, etc., and you can customize character identity to suit different narrative preferences.
Based on GPT model fine-tuning, the AI can generate stories and character reactions with some logical coherence, but the highly open design means the storyline direction is determined entirely by player commands, and coherence depends on the interaction context.
