An Overview of AI Dungeon

AI Dungeon is a text-based adventure game created by Nick Walton and released in 2019. It utilizes a natural language processing AI developed by Anthropic to allow open-ended gameplay. Players can type commands and dialog to direct the story, with the AI generating responsive narrative text on-the-fly. The advanced AI was trained on datasets of text scraped from sites like Reddit, allowing it to mimic human-written stories.

The game quickly developed a following among AI and text adventure enthusiasts. In 2020, it was acquired by Latitude, the company that currently develops and maintains the app. Latitude has continued advancing the underlying AI models used in AI Dungeon to allow for more coherent, creative storytelling.

The Free Version of AI Dungeon

AI Dungeon is free to download and play on both mobile and desktop. The free version gives players access to AI-generated adventures in a variety of genres and settings. These include fantasy, mystery, apocalyptic, and open scenarios where you can prompt the AI with any story ideas.

The free version utilizes a general-purpose AI model called Griffin. Griffin is capable of generating detailed, creative narrative responses based on player input. Furthermore, AI Dungeon provides a contextual memory system that allows the AI to keep track of key story details, locations, and characters.

While functional, the capabilities of the free version are limited compared to premium options. Let’s look at some of the main limitations:

Energy System Limits Play Time

One major limitation of the free version is the energy system. Playing AI Dungeon consumes energy, which regenerates slowly over real time. Running out of energy limits your ability to continue playing. Premium subscriptions remove this energy limit.

This is likely due to the computational cost of generating AI responses. Limiting energy forces breaks between play sessions and reduces overall server load. However, it can disrupt the flow of gameplay.

Access to Advanced AI Models

The general Griffin AI, while impressive, is not as capable as more advanced models. Latitude developed additional AI models like Dragon, which has greater context memory and consistency. However, access to these enhanced models requires a Pro subscription.

Lack of Advanced Features

Premium versions of AI Dungeon unlock special features not available to free users. For example, the Voyage mode provides a 2D visual component with illustrations. Pro users also get access to NSFW content filters and image generation capabilities using DALL-E 2.

Presence of Ads

To offset server costs, the free web version of AI Dungeon displays advertisements during play. These can be distracting and disrupt immersion. The premium version removes ads entirely.

So in summary, the free version of AI Dungeon provides a solid baseline experience, but has constraints on playtime, AI capabilities, and features. Despite the limitations, it remains an excellent way to experience this innovative form of AI-driven entertainment for free.

Premium Subscription Options

For those looking for an upgraded experience, Latitude offers premium subscriptions that lift many of the restrictions inherent to the free version. There are currently two main subscription tiers available:

AI Dungeon Premium ($4.99 per month)

AI Dungeon Premium offers:

  • Unlimited playtime
  • Access to the Dragon AI model for more advanced text generation
  • Additional scenarios, stories, and gameplay modes
  • No ads during play

With Premium, the limitations around playtime and AI model are removed. This allows for more extended adventures and enhanced storytelling from the AI. The expanded content library also provides more variety.

AI Dungeon Pro ($9.99 per month)

AI Dungeon Pro includes all benefits of Premium, plus:

  • Early access to new features and modes
  • Voyage mode with 2D visuals and illustrations
  • Image generation credits for Dall-E 2
  • NSFW content filters
  • Priority model queue times

Pro offers the most capabilities of any tier. The Voyage mode with visuals provides a big expansion on gameplay. Dall-E 2 integration also lets players generate images to accompany stories. And content filtering allows control over narrative themes.

For power users, Pro offers the most feature-rich experience. The priority model queue can also reduce waiting times during periods of peak demand.

Key Questions About the Free Version

To summarize some of the key differences between the free and premium tiers of AI Dungeon, here are answers to some frequently asked questions:

Q1. Is AI Dungeon fully playable for free?

Q3. What are the main limitations I’ll notice in the free version?

The energy system limiting playtime, lack of advanced AI models, and presence of ads during play are the most significant constraints. Access to additional modes and features is also limited.

Q6. Should I consider subscribing if I really enjoy the free version?

If you find yourself limited by playtime or craving more advanced features, a subscription is recommended to get the most out of AI Dungeon. The premium tiers provide a meaningfully enhanced experience.

The Future of AI Dungeon

Part of the excitement around AI Dungeon is bearing witness to the rapid evolution of AI capabilities for entertainment. Since first releasing in 2019, Latitude has consistently advanced the natural language processing power behind AI Dungeon. They also continue expanding available features and storytelling possibilities.

It will be fascinating to see how AI Dungeon continues progressing as artificial intelligence technology matures. With innovations like deep learning, there is potential for AI storytelling to become increasingly multifaceted and engaging. And Latitude themselves are pioneering new directions like visual novel generation with Voyage mode.

For now, the free version provides an excellent way to take AI Dungeon for a spin at no cost. While limited compared to paid tiers, the core text adventure experience remains highly enjoyable. For those seeking to fully immerse themselves in AI Dungeon’s capabilities, premium subscriptions unlock more advanced AI, visuals, and additional features. But the free version remains a remarkable showcase of how AI can generate dynamic, personalized narrative journeys. With future innovation on the horizon, the possibilities are as endless as your own imagination.


AI Dungeon offers a fascinating look into the potential of AI for crafting interactive narratives. While the capabilities of the free version are constrained compared to premium tiers, it remains an impressive demonstration of AI’s creative potential. Limitations around playtime, access to advanced AI models, and availability of premium features are balanced against the benefit of being able to enjoy this innovative game for free. For heavy users and fans eager to experience everything AI Dungeon has to offer, premium subscriptions provide a worthwhile upgrade. But for more casual users simply curious to try this unique form of AI-driven entertainment, the free version provides plenty of accessible fun. As AI technology continues rapidly evolving, we can expect even more advances in the future of AI-generated storytelling.
