SR ★★ Angsty

Fanfic prompt

Any fandom

Character A returns home to find Character B's name removed from every record, photo, and memory of their friends, as if they never existed. Only A remembers, and no one believes them.

R ★ Cute

Fanfic prompt

Any fandom

Character A accidentally adopts a tiny, very dramatic kitten that only wants to sit on their keyboard. Character B insists it's a bad idea, then quietly starts buying it toys.

SR ★★ Cute

Fanfic prompt

Any fandom

Character A and Character B are assigned to co-host a town bake sale but neither can bake anything without it turning into a disaster. They must secretly practice before the big day.

R ★ Funny

Fanfic prompt

Haikyu!!

Hinata gets a fever the night before a big match and insists he's fine. Kageyama shows up at his door with soup and a stern warning, and ends up staying to make sure Hinata actually rests.

SSR ★★★ Soft

Fanfic prompt

Haikyu!!

Kageyama and Hinata are asked to coach a group of nervous first-years, and the kids are much better at reading the two of them than either expected. The two keep stumbling into lessons about teamwork they didn't plan to teach.

How it works

Set the target

Leave it open for character-slot prompts, or name characters and a fandom for prompts written for them specifically.

Pick a tone

Angsty for the 2am feelings, cute and soft for comfort, funny for the crack taken seriously.

Pull three prompts

Each card is a situation with a hook — something that forces characters to act, not just a mood to decorate.

What makes a good fanfic prompt

A good prompt is a situation plus a hook — two characters snowed in is a setting; two characters snowed in, one of them hiding an injury, is a prompt. The hook is the thing that forces someone to act.

This generator deals in hooks. Leave the character field open and you get slot prompts ("Character A…", "Character B…") that work for any fandom; name characters and it writes for them — inside jokes, canon history, the whole texture.

Prompts are free with no sign-up and always safe-for-work. Pull a batch when the doc is empty, or when tonight needs a one-shot idea you did not already have.

FAQ

What is a fanfic prompt here?

A situation with a built-in hook, one to three sentences long — enough to start a one-shot tonight. Each card is a different engine: fluff, angst, comedy, or mystery.

Can I get prompts for a specific ship?

Yes — put both characters in the field (for example "Kageyama & Hinata, Haikyu!!") and the prompts will be written for that pair.

What if I leave the field open?

You get character-slot prompts — "Character A", "Character B" — that you can cast from any fandom. Great for events and prompt memes.

Are the prompts SFW?

Yes. Everything here is safe-for-work, and prompts about real people or explicit content are not allowed.

Is it free?

Free, no account. Pull as many batches as you like within the hourly fair-use limit.
