AI Dungeon 2 represents a groundbreaking moment in interactive storytelling—a GPT-2 powered text adventure that evolved into today’s sophisticated AI Dungeon platform. This game promises infinite stories with complete creative freedom, allowing you to become anyone, go anywhere, and do anything in dynamically generated narratives. From its viral origins as a hackathon project to its current status as a beloved community-driven platform, AI Dungeon has captured the imagination of creative writers, RPG enthusiasts, and AI experimenters worldwide.
What is AI Dungeon 2? Understanding Its Evolution
From Hackathon Project to Viral Phenomenon
AI Dungeon 2 began as an ambitious experiment by Nick Walton, who wanted to create an infinite text-based adventure game powered by artificial intelligence. The original concept quickly evolved when Walton upgraded the system to use GPT-2 1.5B, OpenAI’s then-cutting-edge language model. This upgrade transformed the game from a simple experiment into a viral sensation.
The breakthrough moment came when AI Dungeon 2 was posted to Hacker News in late 2019. The response was overwhelming—so much so that the game’s popularity created serious scaling challenges. Walton famously faced a $50,000 Google Cloud Platform bill as hundreds of thousands of players flooded the servers. This scaling story became legendary in the AI community, demonstrating both the massive appeal of AI-generated storytelling and the infrastructure challenges of democratizing access to large language models.
What started as a solo hackathon project quickly became the foundation for Latitude Inc., a company dedicated to building the definitive AI storytelling platform.
AI Dungeon 2 vs. AI Dungeon: What’s the Difference?
This is perhaps the most common source of confusion for new and returning players. Here’s the definitive answer: AI Dungeon 2 is the historical name for the original 2019 GPT-2 experiment. The platform you access today is simply called AI Dungeon, and it’s a continuously updated, modern service that has evolved far beyond its origins.
The original AI Dungeon 2 was a proof-of-concept that demonstrated the potential of using large language models for interactive fiction. Today’s AI Dungeon is a mature platform with multiple AI models, advanced memory systems, multiplayer capabilities, and even AI image generation.
If you’re visiting aidungeon.com (the official site), you’re accessing the current platform. References to “AI Dungeon 2” in older articles or community discussions refer to the game’s legacy version or early days. There’s no separate “AI Dungeon 2” application to download—it’s all part of the unified AI Dungeon experience managed by Latitude.
How AI Dungeon 2 Works: Features & AI Models
The Power of Generative AI
At its core, AI Dungeon functions as an AI-powered dungeon master for text-based adventures. Using generative AI technology, the system interprets your actions and generates contextually appropriate story responses in real-time. Unlike traditional games with pre-written dialogue trees, AI Dungeon creates an open world where virtually any action you can describe can be incorporated into the narrative.
The AI analyzes your input, considers the story context, and generates realistic responses that move the plot forward. This creates an interactive fiction experience where you’re genuinely surprised by plot twists, character reactions, and world-building details that emerge organically from the AI’s creativity.
Core Gameplay Features
Custom and Prebuilt Scenarios: You can start adventures from scratch with custom prompts or choose from thousands of prebuilt scenarios created by the community. Want to be a space detective? A medieval merchant? A dragon? Simply describe your desired setting and character, or browse the scenario gallery for inspiration.
AI Memory and Story Cards: The memory system allows you to pin critical information that the AI should always remember—character names, key plot points, world rules, and important relationships. Story Cards provide an organized way to track characters, locations, and objects throughout your adventure, helping the AI maintain consistency across long narratives.
Multiplayer Mode: Collaborative storytelling comes alive in multiplayer adventures where you and friends can participate in the same story. Each player can contribute actions, and the AI weaves everyone’s choices into a unified narrative.
Rewind Feature: Made a choice you regret? The rewind feature lets you step back to previous decision points and explore alternative story branches, perfect for experimenting with different narrative directions.
AI Image Generator: Premium tiers include AI-generated images that visualize key moments in your adventure, adding a visual dimension to your text-based stories.
Available AI Models (Dragon, Griffin, and More)
AI Dungeon offers different AI model tiers to balance performance with accessibility. The free version uses capable models that provide solid storytelling experiences with basic context windows. Premium subscribers access more advanced models like Dragon, which offer superior coherence, longer memory, better context handling, and more creative responses.
These finetuned models have been specifically trained on narrative structures and storytelling patterns, making them significantly better at maintaining plot consistency and character development than general-purpose language models. The model you choose affects response quality, speed, and how well the AI maintains story continuity over extended play sessions.

Creating Your First Adventure
Starting your first adventure is simple:
- Choose between a prebuilt scenario or custom prompt. If you’re new, browsing the community scenarios is an excellent way to discover the game’s possibilities.
- If creating a custom adventure, write a detailed opening prompt. Describe your character, setting, and initial situation. The more specific you are, the better the AI can establish the story’s foundation.
- Begin playing by typing actions in either first-person or third-person perspective. Use commands like “I explore the cave” or detailed descriptions like “I carefully examine the ancient runes carved into the stone wall.”
- The AI responds with story developments, and you continue the loop—reading its response, then typing your next action.
Pro Tips for Better Stories
Use the Memory System Effectively: Pin crucial details in the AI memory panel—character names, their relationships, important locations, and core plot elements. This dramatically improves consistency over long play sessions.
Write Detailed Actions: Instead of “I attack the guard,” try “I swiftly draw my hidden dagger and lunge toward the guard’s exposed flank.” Descriptive actions give the AI more context to generate compelling responses.
Engage with Community Scenarios: The community gallery contains thousands of adventures spanning every genre imaginable. Playing popular scenarios shows you what works well and inspires your own creative prompts.
Experiment with Dynamic Storytelling: Don’t be afraid to make unexpected choices. The AI excels at adapting to wild plot twists—this is where the “do anything” promise truly shines.

AI Dungeon 2 Review: Is It Worth Buying?
Based on aggregated user reviews and community feedback, here’s a balanced assessment:
Strengths: AI Dungeon delivers on its promise of creative freedom and endless possibilities. For writers seeking inspiration, RPG fans wanting unique adventures, or anyone curious about AI capabilities, the platform is genuinely impressive. The community is vibrant and supportive, sharing thousands of scenarios. The dynamic storytelling creates genuinely surprising moments—the AI can be funny, dramatic, and sometimes delightfully weird.
Considerations: The AI isn’t perfect. Memory issues can occur in very long stories, where the AI might forget earlier plot points despite using memory features. Content filters, implemented to address safety concerns, occasionally trigger on innocent content, which has frustrated some users. Performance can vary—free tier users may experience slower response times during peak hours.
Verdict: The free version is absolutely worth trying for anyone interested in AI storytelling or interactive fiction. For serious users who play regularly, the premium subscription offers meaningful improvements in story quality and coherence. It’s particularly valuable for creative writers, D&D players seeking inspiration, and AI enthusiasts. Casual gamers might find the text-based format less immediately engaging than visual games, but those who appreciate narrative depth will find AI Dungeon addictive.
Addressing Common Questions and Concerns
Is AI Dungeon 2 Safe and Legit?
This is a common concern, especially given the somewhat unusual nature of AI-generated content. The direct answer: Yes, AI Dungeon is a legitimate service developed by Latitude Inc., a real company backed by investors and available through verified app stores.
Regarding data safety, Latitude’s privacy policy outlines their practices. Data transmitted between your device and their servers is encrypted. You can delete your data at any time through account settings. Stories marked as private remain private—they’re not shared with the community or used for public purposes without your consent.
The confusion around legitimacy often stems from the game’s rapid evolution, past controversies around content moderation, and the general skepticism some people have about AI-powered services. However, AI Dungeon has been continuously operating since 2019, maintains official presence on major app stores (which have verification requirements), and has an active, engaged community.
Trust signals include: official verification on Google Play Store and iOS App Store, transparent developer information (Latitude Inc.), active customer support, regular updates, and positive ratings across platforms despite some vocal criticism about specific features.
Troubleshooting Common Problems
Slow Performance: Response times can vary based on server load and your subscription tier. Premium users get priority queue access. If experiencing consistent slowness on the free tier, try playing during off-peak hours or consider upgrading.
App Crashes: If the mobile app crashes frequently, ensure you’re running the latest version. Clear the app cache, restart your device, or try reinstalling. For persistent issues, contact Latitude’s support team through the app or website.
Device Compatibility and Old Phones: AI Dungeon is relatively lightweight since the AI processing happens on Latitude’s servers, not your device. However, very old phones with outdated operating systems may experience compatibility issues. The web version through a mobile browser often works when native apps don’t.
Memory Issues: When the AI “forgets” important details, it’s usually because the context window has been exceeded or memory pins weren’t used effectively. Key information should always be added to the Memory panel. For critical plot points, occasionally reminding the AI in your action text helps maintain continuity.
The Legacy and Community of AI Dungeon
A Community-Driven Project
From its earliest days, AI Dungeon’s development was shaped by community support. The original project gained momentum through Patreon backing when Walton needed to cover server costs. As the game evolved, the community contributed scenarios, provided feedback that shaped feature development, and created a supportive ecosystem for new players.
Today, the community remains vibrant. The scenario gallery showcases player creativity across thousands of shared adventures. Reddit communities discuss strategies, share funny AI moments, and provide troubleshooting help. This collaborative spirit reflects the open-source ethos that informed AI Dungeon’s origins, even as it evolved into a commercial platform.
The Cultural Impact
AI Dungeon occupies a unique space in AI culture as one of the first applications that made large language models accessible and fun for ordinary users. The early AI Weirdness blog coverage perfectly captured what made AI Dungeon special—it wasn’t just functional, it was entertainingly unpredictable.
The game became famous for enabling absurd scenarios impossible in traditional games. Want to become a dragon and eat the moon? You can. Want to have philosophical debates with sentient cheese? The AI will play along. This creative freedom sparked countless viral stories and memes, establishing AI Dungeon as a cultural touchstone in the broader conversation about AI capabilities and limitations.
For many people, AI Dungeon was their first meaningful interaction with AI-generated text, making it an important educational tool that demystified language models years before ChatGPT made headlines.
