RedQuill vs NovelAI

Co-writer or full storyteller?

Updated October 27, 2026

Short answer

NovelAI is a co-writer: you write, it continues your text, and you tune it with a Lorebook, Memory and deep generation settings. RedQuill is a storyteller: one line becomes a full chapter, and you steer the next one in plain words.

Does NovelAI allow NSFW?

Yes. NovelAI is an adults-only service built for writing whatever you want.

Rules
NovelAI's terms say you must be 18 or older. They focus on account and payment misuse, not on banning story themes, and NovelAI says it offers "an unprecedented level of freedom."
Privacy
Stories are encrypted in your browser before they're stored, and NovelAI says it can't read them. It also says it doesn't log the content of your requests without your consent.
Free trial
An email-verified account gets 50 text generations, 30 images and 100 text-to-speech generations, once. After that, writing needs a subscription.
Your effort counts
NovelAI continues what's on the page. Its own FAQ puts it plainly: the more effort you put into your writing, the better the AI's output.
In practice
NovelAI will write explicit scenes. It's best for people who like to write alongside the AI and tune how it behaves, not for people who want a finished chapter from one line.

Where NovelAI is the better choice

NovelAI is a serious tool for hands-on writers. For these jobs, it beats RedQuill.

  1. Line-by-line co-writing. You write a sentence, it writes the next few, and you edit anything. If you want your own voice on every line, this is the workflow.
  2. Deep control. Pick the model, tune generation settings, and use Phrase Bias to make the AI favor or avoid certain words.
  3. A very powerful Lorebook. Entries switch on when their keywords show up, with options like regex keys and advanced conditions. You can import, export and share Lorebooks.
  4. Privacy first. Encrypted stories, an option to store them locally, and one-click export of all your stories.
  5. A full anime image generator. Every tier includes a standalone image tool, and Opus makes standard-size images without spending Anlas, within its limits. RedQuill can illustrate scenes in your story, but it isn't a standalone art studio.

Where RedQuill is the better choice

RedQuill does the heavy lifting NovelAI leaves to you, so you can spend your time reading and steering.

Explicit stories without tuning settings first

On NovelAI, the result depends a lot on your setup. 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, in one step.

One line gets you a full chapter

There's no blank page to fill first. Type "my rival and I get snowed in at a ski lodge" and RedQuill writes a full first chapter in under a minute. Then continue chapter by chapter, steer the next scene in plain words, rewrite any paragraph with AI (keep it or undo it), or fork the story to try another direction. Want to see a moment? Illustrate any passage to add a picture right in the chapter.

Saved characters that carry across stories

NovelAI's Lorebook is powerful, but you build and tune each entry. On RedQuill, you save characters once (looks, personality, history, how they talk) and reuse them in any story. Each story also keeps its own Lorebook, so chapter 12 still remembers what happened in chapter 2. Learn more in Characters 101.

Play the scene, not just the text

Roleplay mode is RedQuill's answer to Text Adventure. Step into any chapter, or any paragraph while reading, as a character. The AI narrates the world and plays every other character in the scene. A Cast panel tracks who's there, where they are, what they're wearing, their mood and what they're secretly thinking.

A community library to read and fork

NovelAI stories are shared by exporting files. RedQuill is also a reading platform: 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.
