About this tool
Generate story prompts filtered by genre, tone, setting and character type, each with a want, an obstacle, a twist and a word target.
A story prompt generator that builds each idea as a complete logline — protagonist, want, obstacle, setting and stakes — rather than a one-line 'what if'. Choose from ten genre packs, eight tones and twelve character types, and every prompt also names a reversal to aim at, a first line and a word target (100, 750, 3,500 or 7,500 words). Writers use it to break a blank page, run timed sprints, or set exercises for a workshop.

Each prompt carries a protagonist, a want, an obstacle and stakes, so the story has a shape before you type.
Settings and reversals come from a pack built for that genre, so a fantasy prompt never borrows a courtroom from a thriller.
The same seed rebuilds the same batch, so you can share a prompt with a writing partner by sending one number.
A usable prompt names who wants something, what stands in the way, and what it costs to fail — the classic logline shape. A prompt that is only a setting or only a twist leaves the hardest work undone, which is why every prompt here fills all four slots plus a reversal.
Pick the target that matches where you want to submit: 100 words for a drabble, up to about 1,000 for flash fiction at most journals, and up to 7,500 words for the short-story category as defined by SFWA's award rules. The tool sets a target of 100, 750, 3,500 or 7,500 words and tells you how much structure that length supports.
Yes. A premise or idea is not protected by copyright — only the expression is — so the story you write from a prompt is your own work. Crediting the generator is optional and never required.
The seed makes the output reproducible: the same genre, tone, character, length and seed always produce the same prompts. Change it to shuffle, or note it down so you can bring back a prompt you liked without copying the text.
