AI Dungeon Alternatives – A Deep Dive into 15 Text Adventure Games Powered by AI

AI Dungeon pioneered a revolutionary concept – text-based games with adventures and narratives generated on-the-fly using AI. As you type, the advanced natural language model crafts a story tailored to your inputs and choices. This sparks the imagination in ways never before possible.

But AI Dungeon is far from the only option today. A range of alternatives have replicated and expanded on the text adventure formula powered by artificial intelligence.

In this comprehensive guide, we‘ll analyze the top 15 AI Dungeon alternatives in-depth. We‘ll compare their technology stacks, capabilities, limitations, and more so you can find the right fit for your creative needs.

Understanding the AI Behind AI Dungeon-Style Text Games

Let‘s first demystify the artificial intelligence driving these tools. Most options today leverage variants of natural language processing (NLP) models like GPT-3, created by AI research company OpenAI.

GPT-3 is a transformer-based language model with over 175 billion parameters. It‘s trained on massive datasets to generate impressively human-like text. The key strengths:

  • Text fluency – outputs are coherent, nuanced, and grammatically correct
  • Contextual awareness – adapts tone/style based on the prompt
  • Knowledge capacity – can reference facts and concepts like a human

However, GPT-3 has some key limitations:

  • No true understanding – it predicts words statistically but doesn‘t comprehend meaning
  • Lacks common sense – can generate logically inconsistent or unethical text
  • Not customizable – outputs don‘t adapt to user‘s style/preferences over time

Let‘s see how different AI Dungeon alternatives stack up given these AI model strengths and limitations:

1. NovelAI

NovelAI is built using Anthropic‘s open-source Claude AI model. Claude has comparable capabilities to GPT-3 but with critical innovations:

  • Self-supervision – Claude trains some parameters based on its own outputs, allowing customization to user preferences over time.
  • Consistency – special encoder modules ensure logical consistency in generated text.
  • Controllable – tunable parameters to adjust levels of creativity vs. caution in generation.

This results in rich, customized text adventures with more plot/lore cohesion than typical language models like GPT-3. Users praise NovelAI for strong narrative development and smart virtual assistants.

Downsides include a smaller user base vs. competitors (currently 25K+ monthly users) and pricing that starts at $10/month. But for rich, tunable AI adventures, NovelAI is a top choice.

2. InferKit

InferKit leverages a proprietary AI model called INFKT. While the architectural details are scarce, users describe high-quality outputs on par with GPT-3.

INFKT seems optimized for content creation use cases. It adeptly composes long-form stories, articles, advertisements, and more based on sparse inputs. Reviews praise InferKit for enabling rapid drafting and brainstorming through A.I.

For crafting text adventures, InferKit is likely limited by GPT-3‘s weaknesses around logical inconsistencies and lack of true comprehension. But as a springboard for ideas and prototypes, it‘s highly potent.

Pricing starts free for limited use up to $30/month for advanced plans. InferKit is easy to try out and offers strong general NLP capabilities.

3. Shortly Read

Shortly Read combines GPT-3 with an added content classification model. This allows tailoring the tone, complexity, conciseness and structure of generated text without user prompting.

For text adventures, this equates to adjusting story pacing, description density, dialogue, etc. automatically based on the evolving narrative. The AI adapts more intelligently to plot progression compared to a context-free model like GPT-3.

Shortly Read is best for drafting structured narratives like fiction books. But the quality varies, so extensive human editing is still required. Pricing starts at $7/month for 1,000 words of generated content.

4. Rytr

Rytr leverages the Megatron Turing NLG 530B model – an impressively large GPT-3 variant with 530 billion parameters. This massive model size enables exceptional fluency and coherence in generated text.

Rytr is optimized for business writing like blogs, ads, emails, etc. But the robust foundation could be apt for text adventures too. With strong technical writing skills, the AI could craft detailed sci-fi/fantasy worlds or explain in-game mechanics fluently.

Downsides may include higher cost ($20/month minimum) and limited creative writing abilities. But Rytr demonstrates how scaled-up AI models continue advancing text generation capabilities.

AI Text Adventure Showdown: 3 Sample Outputs Compared

To better showcase quality differences in text generation, below are sample outputs from 3 top AI Dungeon alternatives prompted to continue a sample story starter:


You enter the mysterious cave, torch in hand. As the light flickers against the stone walls, you hear a faint dripping sound deeper in the darkness. Your footsteps crunch softly on the gravelly floor and your heart beats faster. Up ahead, the cave narrows into a tunnel barely wide enough to squeeze through…

NovelAI output:

Taking a deep breath, you turn sideways and edge into the tight crevice, trying not to scrape against the rough walls. You feel an oppressive weight pressing down on you in the cramped space. After several tense moments, the passage opens up into a larger cavern. You sigh in relief and raise your torch to illuminate the area. Your eyes go wide at what the firelight reveals.

Strange runic symbols are etched all around the circular room. In the center lies a small, clear pool with a faint glow. You crouch down at the water‘s edge, overcome by curiosity. What could be the source of the strange light in these underground depths? As you peer closer, the surface begins swirling rapidly. You stumble back in alarm as a raspy voice echoes in your mind…

This continuation reflects NovelAI‘s strengths at lore generation and tension building. The descriptive prose draws you into the underground setting with nuanced details. A sense of mystery builds as strange events unfold.

Shortly Read output:

*You continue forward, ducking your head as the tunnel tightens around you. It feels as if the rock walls are closing in, ready to trap you in an inky tomb. But you push ahead, one hand brushing stone to guide you as the torchlight dims.

Just as your nerves reach a breaking point, the tunnel opens into a glittering cavern. You gasp in awe at the sight – giant crystals in shades of purple, green and blue jut from the floor and ceiling. In their faceted surfaces, your torchlight fractures into dazzling rainbow beams.*

Shortly Read‘s output displays strong descriptive voice and emotional resonance. The AI generates tense psychological dynamics and curious, abstract details that propel the story.

InferKit output:

*As you squeeze through the narrow tunnel, you feel the air around you grow cold. Your torchlight flickers, casting dancing shadows against the rock. Suddenly, you hear a sharp skittering sound right behind you. You whip around, holding the torch out to illuminate the darkness.

A hairless, albino creature with sunken eyes and sharp claws scampers back from the light, hissing. More sets of glowing eyes begin to emerge from the depths of the tunnel. The creatures inch closer, surrounding you. Your hand tightens on your weapon as the lamp flickers weakly. How will you fight your way out of this underground trap?*

InferKit took a more plot-driven approach, introducing creatures to raise stakes and tension. This propels the story into confrontation rather than just environmental exploration.

As you can see, quality varies greatly across AI models. Factors like training data, model size, prompt engineering and creative boldness all contribute to engagement and coherence.

Now let‘s continue exploring more AI Dungeon options to see different strengths and weaknesses…
