  1. Person A and Person B get caught in a sudden downpour on a hike and strip to their underwear in a rented cabin, laughing until the laughter turns into something slower and heavier.

  2. Person A loses a bet and owes Person B a full-body massage. Halfway through, Person B rolls over and asks if the stakes can change.

  3. Person A and Person B are rival food-truck owners parked side by side at a night market. After closing, they share a bottle of wine and finally admit the tension was never about the customers.

  4. Person A finds Person B still awake at 3 a.m., both jet-lagged in a shared hotel room, and suggests a game of truth or dare to pass the time.

  5. Person A and Person B, dance partners for years, rehearse alone in the studio after hours. The music ends, and neither of them lets go.

A sensible person who seriously handles errands, odd jobs, and peddling medicine at Eientei. The teased one and the long-suffering one. Cheerful, curious, and easily carried away.

When she drinks an aphrodisiac…

What is an NSFW prompt?

An NSFW prompt is a starting point for an explicit scene: a situation, a line of dialogue or a headcanon that tells you who, where and what the tension is, and leaves the writing to you. Fanfic writers trade smut prompts on Tumblr and in Discord servers, and prompt fills are how a lot of AO3 works begin.

Most NSFW prompt generators pick from a fixed list of a few hundred prompts, so the same ones come round again. This one writes new prompts every time, for the pairing, heat and tropes you give it.

How to get better smut prompts

  • Name the pairing. Type your two characters. The prompts are written around who they are, and Swap flips who takes the lead.
  • Pick one or two tropes. Enemies to lovers or only one bed gives the AI a reason for the tension.
  • Set the heat. Fluffy for slow burn, Explicit or Filthy for smut prompts that go all the way.
  • Press More like these. You get new prompts without losing the ones you already like.

NSFW headcanons and dialogue prompts

Switch the prompt type to Headcanons for NSFW headcanons about how your pairing is in bed, or to Dialogue for spicy lines you can build a scene around. Mixed gives you a little of each.

Found one you want to write? Press Write this story and the prompt opens in the AI smut writer, ready to turn into a full scene.

NSFW prompt generator questions, answered

Is this NSFW prompt generator free?
Yes, with no account. Every visitor gets a number of AI-written prompt sets a day, counted under the button, and written example prompts are always there after that.
Is it for adults only?
Yes. The prompts are sexual and meant for adult writers. Every character is written as 18 or older and every scene is consensual, and a request that names or implies anyone younger gets written prompts instead.
Can I use my own OTP or characters?
Yes. Type any two names and pick their genders. The prompts are written around that pairing, and you can change the names afterwards without asking the AI again.
What does Swap do?
Swap trades the two names in every prompt on the page, so the one who takes the lead becomes the one who follows. It happens straight away in your browser, with no new request.
What kinds of prompts can it write?
Scenario prompts that set up a situation, dialogue prompts built around a spicy line, NSFW headcanons about how the pair are together, or a mix. Pick the type before you press the button.
How spicy are the prompts?
You choose. Fluffy keeps it soft and romantic, Steamy puts sex on the page without graphic detail, Explicit is fully explicit, and Filthy goes as far as it gets, with dirty talk.
Can I turn a prompt into a story?
Press Write this story on any prompt. It opens the AI smut writer with that prompt already in the brief, so you can get a full explicit scene written from it.
Can I use the prompts on AO3 or Tumblr?
Yes. Use them for prompt fills, writing challenges, fic exchanges or your own drafts. No credit is needed, though a link back is always welcome.
Is anything I type stored?
Yes. What you type, names included, is sent to the AI to write the prompts, and a copy is kept with the result so we can see how the tool is used and make it better. It is never published or shared, and you never need an account.
What languages does Rabu AI support?
Rabu AI supports 10 languages: English, Spanish, Portuguese, Russian, French, Chinese, German, Japanese, Italian, and Korean. Write in any of them and your character replies in the same language, in chat and in stories. Voice messages and videos speak it too.
