Story ideas

Over 60 short story ideas sorted by genre, a generator with thousands more, and the collision method for brainstorming your own.

Genre
Story idea

A man who has never told a lie discovers their neighbour has been writing about them. The catch: they can only tell the truth until sunrise.

The collision method: where ideas come from

Most story ideas are not invented from nothing. They come from colliding two ordinary things that rarely meet, then adding a problem. Hit "Collide" and look for the story in the gap.

A persona hospital chaplain
An odd placea night market in a port city
A problemthey are lying about who they are

Ask: why is a hospital chaplain in a night market in a port city? What do they want there, and why does it matter that they are lying about who they are? Your answers are the story.

Story ideas on your theme

Give the AI a theme, a subject or a feeling (grief, a heatwave, an inheritance) and get five distinct story ideas built around it.

AI output is generated by openai/gpt-6-luna via Vercel AI Gateway. It can be wrong or odd; the prompt lists on this page work without it.

Three more ways to brainstorm story ideas

  1. What if, applied to routine. Take something you did today (queueing for coffee, a commute) and change one rule. What if the queue decided your future?
  2. Swap the expert. Put a total amateur in a situation genre usually gives to an expert: a florist in a heist, a toddler's grandmother in a spy plot.
  3. Steal from history. Pick a strange true event from a local museum or archive and move it to a new time or world.

Turn your idea into a full premise with the plot generator, then give it a name with the book title generator.

Questions writers ask

How do I come up with story ideas?

Combine two things that do not usually go together (a job and an unlikely place, a familiar routine and one impossible change), then ask what goes wrong. Most strong ideas are a collision plus a problem, not a single flash of inspiration.

What makes a good short story idea?

A short story works best with one character, one central change and a small cast and timeframe. Look for ideas that can turn on a single moment or decision.

Where do professional writers get ideas?

Many describe keeping an idea notebook, reading news and history, eavesdropping on real dialogue, and asking "what if?" about ordinary situations. Stephen King's On Writing describes ideas arriving when two unrelated thoughts collide.

Are these story ideas free to use?

Yes. Ideas themselves are not protected by copyright, and the story you write from one is yours.

Can I get story ideas for a specific theme?

Yes. Use the AI box to type any theme or subject, and pick a genre on the generator for a random combination.
