RedQuill vs AI Dungeon
Which AI for adult stories?
Updated October 27, 2026
AI Dungeon is a text adventure game: you type what your character does, and the AI narrates what happens next. With its Mature setting on, it allows adult content. RedQuill is built for adult stories: one line becomes a full chapter, you continue chapter by chapter, and Roleplay mode is there when you want to play a scene.
Use AI Dungeon to play an open-ended adventure turn by turn.
Use RedQuill to write and read explicit stories that build over many chapters.

RedQuillDoes AI Dungeon allow NSFW?
Yes, once you change one setting. Out of the box, it doesn't.
Where AI Dungeon is the better choice
AI Dungeon is the original AI adventure game. For these jobs, it beats RedQuill.
- True open-ended play. Type anything your character does or says, and the world reacts. If you love the game loop of action and reply, nothing feels more like it.
- Thousands of scenarios. Players publish ready-made worlds and setups, so you can jump into someone else's adventure in seconds.
- A free tier to play on. You can play without paying. Paid tiers mainly add stronger models, more context and more memory.
- Model choice. You can pick from many AI models, with more on paid tiers.
- Image credits included. Paid plans include monthly credits you can spend on generating images for your adventure. RedQuill can illustrate scenes too, but each picture costs quills.
Where RedQuill is the better choice
RedQuill is built for adult stories first, with play as a tool rather than the whole product.
It's built for explicit stories
There's no safety setting to find first. RedQuill is made for adult fiction, including kinks and power dynamics, within our content guidelines. The spicy level control sets how far each story goes, from slow burn to fully explicit.
One line becomes a full chapter
In AI Dungeon, you write every turn and the AI answers a paragraph at a time. In RedQuill, type "my rival and I get snowed in at a ski lodge" and you get a full first chapter in under a minute. Then steer the next chapter in plain words, edit any paragraph, illustrate a scene, or fork the story to try another direction without losing the original.
Your characters stay consistent
Long adventures tend to drift as details fall out of the AI's memory. In RedQuill, you save characters once (looks, personality, history, how they talk) and reuse them in any story. Each story also keeps a Lorebook, so chapter 12 still remembers what happened in chapter 2. Learn more in Characters 101.
Play a scene when you want to
Roleplay mode drops you into any chapter as a character, or starts from any paragraph while you read. The AI narrates the world and plays everyone else in the scene. Type what you do or say, or let the story move on its own. A Cast panel tracks where everyone is, what they're wearing, their mood and what they're secretly thinking. When you're done, you're back to a story with real chapters.
There's a library to read
RedQuill is also a reading platform. Thousands of public stories are free to read on Discover, and you can fork any of them into your own version. Your own stories stay private unless you publish them.
