Most writing prompts fall into one of two traps. Either they're so vague they're useless, "write about a journey," or they're so specific they basically write the story for you and leave nothing for your imagination to do. The prompts below try to sit in the middle ground, specific enough to spark something immediately, open enough that ten different writers would take them ten different directions.
Use these as warm ups, as the seed of a short story, or as a way to break through a stuck manuscript by writing something unrelated for twenty minutes. Sometimes the side door works better than pushing harder on the front one.
Character driven prompts
These focus on giving you a person first and letting the story grow out of who they are.
- A locksmith who has never once been able to open the lock to their own front door without help.
- Someone who inherits a stranger's diary and slowly realises the writer knew things about their own life they never told anyone.
- A retired translator who starts hearing conversations in languages they don't actually speak.
- A person who has worked the night shift at the same petrol station for fifteen years and has never told anyone what they saw on their first night.
- Two siblings who haven't spoken in a decade, forced to clean out their late parent's house together.
- A character who is excellent at giving advice and terrible at taking their own.
- Someone who discovers their childhood imaginary friend has been writing letters to them for years, only they were never delivered.
- A person who collects other people's lost items and tries to return them, one at a time.
Setting and atmosphere prompts
Start with a place and let the mood do the heavy lifting.
- A laundromat that is open all night and never seems to have any other customers, except it always smells faintly of someone else's cooking.
- A small coastal town where the tide goes out further every year and nobody talks about what it's uncovering.
- An apartment building where every tenant swears the lift stops on a floor that doesn't exist, but only ever alone.
- A library in the basement of a house that nobody in the family remembers building.
- A train that runs one stop longer than it's supposed to, every single time, and nobody has ever reported it.
- A garden that blooms completely out of season every year on the same date, for reasons no one in the family will explain.
- A diner at the edge of a town that's been slowly emptying out for twenty years, still serving a full breakfast menu every morning.
- A shop that sells only one item per customer per lifetime, and nobody remembers who decided the rule.
Conflict and tension prompts
Built around a decision point or a pressure that won't let the character sit still.
- A character finds proof that someone they love did something unforgivable years ago, and has thirty seconds to decide whether to bring it up before the moment passes.
- Two former best friends are stuck working the same job after one of them caused the other to lose everything.
- A character has to choose between keeping a promise to someone who has died and protecting someone who is still alive.
- Someone discovers their closest friend has been quietly sabotaging them for reasons that, once explained, are almost understandable.
- A character is offered exactly what they've always wanted, on the condition that they never ask how it became possible.
- Two strangers are stuck somewhere together for one night, and only one of them knows they've met before.
- A character has to deliver news they know will end a relationship, and they have exactly the length of one car journey to do it.
- Someone realises, halfway through an argument, that they're actually angry about something completely different.
Genre bending prompts
For when straightforward realism feels too small for the idea.
- A world where memories can be physically traded, and a black market has grown up around people's worst ones.
- A detective whose only clue is a recurring dream that seems to be one chapter ahead of the actual case.
- A small town where everyone ages normally except for one street, where time moves at half speed.
- A character who can hear the last thought of anyone who has died in a particular building, but only that one building.
- A future where letters are the only form of communication considered legally binding, and someone is forging them for profit.
- A historical figure's untold side of a famous event, told from a perspective history completely left out.
- A world where every lie spoken out loud becomes visible as a faint mark on the speaker's skin.
- A character who wakes up with someone else's skill set and absolutely none of their memories.
Flash fiction prompts
Short and tight, built for stories under a thousand words.
- Write a story that takes place entirely in the time it takes a kettle to boil.
- A goodbye that the reader only realises is permanent in the final line.
- A character cleaning out a wallet found on the street, told only through the items inside it.
- The last entry in someone's diary before they disappear, written so the reader understands more than the narrator does.
- A conversation between two people where neither says what they actually mean, and the reader has to read between every line.
- A single object passed between three different owners over fifty years, told in three short scenes.
- The exact moment someone decides not to say something, and everything that almost happened if they had.
- A story told entirely through the things left unsaid in a single phone call.
How to actually use these
Pick the prompt that makes you slightly uncomfortable rather than the one that feels easiest. The easy ones usually produce flat first drafts because there's no real tension pulling you forward. The uncomfortable ones, the ones where you're not sure how the character would react, tend to produce the most honest writing, because you have to actually think your way through it rather than coast on instinct.
If nothing on this list grabs you immediately, try combining two from different categories, a setting prompt with a conflict prompt, for example. Some of the most interesting stories come from collisions that weren't originally designed to fit together.
