Before

Write a scene where two rivals get stuck together during a storm and talk honestly for the first time.

After

Thunder rattled the café windows hard enough to make the hanging lights tremble. Izuku had meant to keep his head down—wipe the counter, restock the cups, pretend the world wasn’t shaking outside.

Then the back door slammed, and Bakugo was there, soaked through, scowling like the weather had personally offended him.

“Of course you’re here,” Bakugo snapped, dragging a hand through wet hair. Water dotted the floor in angry little puddles.

Izuku swallowed. “I work here.”

“Yeah. I noticed.” Bakugo’s gaze flicked to the CLOSED sign, then to the hallway. Another crack of thunder. The building’s old alarm chirped once—like it was thinking about it.

The lights blinked. Once. Twice.

And then the power cut.

For a second, the only sound was the rain—relentless, intimate—like the world had leaned in to listen.

Izuku fumbled for his phone flashlight. “The breaker’s in the back. Come on—”

“I know where it is,” Bakugo muttered, but he followed anyway.

The storage room was narrow and crowded with boxes that smelled like cardboard and cinnamon syrup. Izuku squeezed past a stack of deliveries, reached for the panel—

A gust shoved the back door. The latch clicked.

Bakugo went still.

Izuku tried the handle. It didn’t budge.

Bakugo exhaled through his nose, a sound halfway between a laugh and a threat. “You have got to be kidding me.”

Izuku’s heart thudded. “It’s just a door. We’ll— we’ll figure it out.”

Bakugo’s eyes, usually all fire, were something else in the dark. Tired. Too honest.

“Midoriya,” he said quietly, like the name didn’t fit in his mouth anymore. “Do you ever get sick of trying so hard?”

Izuku blinked. The question landed like a confession.

Outside, the storm kept talking.

In the cramped dark between boxes and breath, Izuku realized this might be the first time Bakugo had ever asked for anything that wasn’t a fight.

And for once, Izuku didn’t reach for the right answer.

He reached for the real one.

Pro Tips for Better Results

Get the most out of the AI Fanfiction Generator with these expert tips.

Use a trope + a constraint

Combine a trope with a specific constraint for stronger scenes (e.g., "enemies to lovers" + "stuck in an elevator" + "only one umbrella").

Give one-line character notes

Add quick notes like “X is blunt but protective” or “Y hides feelings behind humor” to improve voice and dialogue consistency.

Ask for a hook and a payoff

If you want a satisfying one-shot, include what the opening should tease and what the ending should deliver (confession, reconciliation, reveal).

Generate two versions, then merge

Try different modes (Canon-Compliant vs. Slow Burn) and combine the best lines, pacing, and emotional beats into your final draft.

Generate fanfiction that actually feels in character

Most “fanfiction generators” spit out a generic scene where everyone talks the same. Which is… fine, I guess, if you only need a vague idea. But if you want something you can post (or at least edit into something postable), you need a tool that can hold onto voice, relationships, and the little rules of the world you are writing in.

This AI Fanfiction Generator is built for that sweet spot: fast inspiration, but with enough structure and dialogue that it reads like a real scene and not a summary.

What you can create with this fanfic generator

You can use it for quick one-shots, missing scenes, or even as a starting draft for a longer fic. A few common setups people use it for:

  • Canon-compliant moments: off-screen conversations, aftermath scenes, character studies
  • Ships and gen: romance, rivals-to-lovers tension, found family, platonic soulmates, all of it
  • AU writing: coffee shop, college, fantasy, modern, workplace, time loop, you name it
  • Trope-driven scenes: hurt/comfort, fake dating, only one bed, enemies to lovers, slow burn
  • Dialogue-heavy chapters: banter, arguments, confessions, emotional clean-up after a fight
  • Multi-chapter planning: outlines you can expand chapter by chapter (especially if you write on AO3 or Wattpad and want a steady arc)

The inputs that matter most (and why)

You do not have to fill everything in, but these fields noticeably change the output:

1) Story prompt or scenario
This is the engine. If you only write “make them talk,” the tool has to guess the tension, setting, and payoff. Give it a situation and an emotional beat. Example:
“After a failed mission, Character A patches up Character B. They almost admit feelings, but back out. End with an interrupted moment.”

2) Characters and pairing
Even a comma-separated list helps, but if you can add micro context in the prompt, it gets better fast.
“X is blunt but protective. Y jokes when nervous. They have history, not trust.”

3) POV + tense
If you want that close, fic-like interiority, pick third limited and tell it whose head we are in. If you want immediacy and momentum, present tense can work really well for action scenes.

4) Mode (fluff, angst, slow burn, canon-compliant, AU, action)
Mode is basically a steering wheel. Same premise, totally different vibe. If you are not sure, start with Canon-Compliant or Slow Burn, then regenerate once with Angst and steal the best bits from both.

A simple prompt template you can copy

If you ever blank out at the prompt box, use this and fill in the brackets:

Fandom: [name or short description]
Characters: [names]
Dynamic: [rivals, friends, exes, strangers, mentor/student, etc.]
Trope/AU: [hurt/comfort, fake dating, coffee shop AU, etc.]
Setting: [where and when]
Goal: [what you want the scene to accomplish]
Must include: [a line of dialogue, an object, a reveal, a kiss that almost happens]
End on: [cliffhanger, confession, reconciliation, quiet intimacy]

How to get more “in-character” results (without writing a bible)

A weirdly effective trick: add two bullets per character in the prompt. Not paragraphs. Just enough to lock in voice.

Example:

  • Character A: direct, uses short sentences, hates being vulnerable
  • Character B: overthinks, tries to lighten tension with humor, notices details

Also, include one “rule” the scene should follow.
Like: “No instant forgiveness,” or “They don’t say ‘I love you’ yet,” or “Keep it canon-safe, no AU changes.”

Can you post what it generates?

Use it as a draft and revise. Most writers do anyway, even when they write fully by hand. Clean up wording, make choices more specific, add your personal flair, and you will end up with something that feels like yours.

If you are building a whole writing workflow around it, you can pair this with other tools on WritingTools.ai to polish scenes, rewrite dialogue, or tighten pacing after you generate the first version.

Quick note on rating and content

If you choose a Mature style, you can lean into intense romance and fade-to-black intimacy, but it will still avoid explicit sexual content. That is intentional, and it keeps the output usable on more platforms with less cleanup.

If you want the output to feel less “AI”

Try this: ask for imperfection. Seriously.
Add a line like: “Include interruptions, half-finished sentences, and small physical beats (pauses, looks, nervous gestures).” It makes dialogue land more naturally, and the scene stops feeling overly polished in a weird way.
