How it works
These sci fi prompts are built from four lists of 60: a place, a person, a discovery and a catch. Space, aliens, robots, time travel and the near future are all in the mix, so one press can land anywhere.

Four parts, and the catch matters most
A discovery on its own is a fact. The catch turns it into a story, because it says why the obvious fix will not work. Lock a discovery you like, say that the aliens are allergic to music, and reroll the catch until the problem hurts: the whole world is watching live, or only one person on Earth can talk to them.
Science fiction short story prompts, one scene each
Deal one premise and write the moment the character learns the truth, in under a thousand words. Start the ten-minute timer for a first draft. The mix is often the best part: a care home staffed by machines meets a time traveller on a budget.
- Lock the hero and the catch, then reroll the setting three times: the same problem reads differently on a comet and in a flooded city.
- Swap the character's job for your own and see what the story becomes.
Questions and answers
Is this a sci fi story generator or a prompt list?
Both. Each press builds a premise from four lists, and every entry is printed under the tool, so you can read the lists and pick parts by hand instead. It deals premises, not finished stories.
Does it cover aliens and space travel?
Yes. Each list is sorted under five kinds of science fiction: deep space, first contact, robots and AI, time and memory, and near-future Earth. The tool mixes them; the full list shows which is which.
Can I use the prompts for a class or a writing group?
Yes. Print a sheet of 30 premises and hand each writer one. Every prompt is made from our own lists and names no book, film or series.
