Story Generator — Seeded Arcs and Honest Reversals
Deterministic client-side arc engine; optional user-key Gemini polish.
Quick answer: Generate short stories from seeded genre arcs (want → obstacle → reversal → cost). Same seed, same story — iterate like a director. Optional Gemini pass with your own key.
How to use
- Pick genre + tone, set seed.
- Generate beats.
- Optional Gemini polish; copy and expand.
About this tool
Random-text generators are slot machines; this one is a writer's bench. Every story is built from a genre arc — a concrete want, an obstacle that costs something, a reversal that re-contextualizes the want, and an ending that pays the cost — driven by a seed you control. Same seed reproduces the same story, so you can tune genre, tone and length deliberately instead of re-rolling. The engine outputs clean beats (scene-by-scene), ready to expand by hand; paste your own Gemini key (memory-only) for a prose pass. Your file never leaves this page — processing runs in your browser via WebAssembly; nothing is uploaded and the file is dropped from memory when you close the tab.

From genre and seed to a working outline
The AI story generator turns three inputs — a genre, a numeric seed and a protagonist — into a scene-by-scene beat outline you can expand into a draft. Try it: set the genre to thriller, type 'a night-shift pharmacist' into the protagonist box, leave the seed at 7, and hit Generate beats. What comes back is roughly 400 to 700 words of beats with a real spine — a concrete want, an obstacle that costs something, a reversal that re-frames the want, an ending that pays the cost. Change the seed to 8 and the same pharmacist gets a different arc. Switch back to 7 and the identical outline returns, every time.
The craft tip: write down seeds that worked. Since the same seed plus settings always reproduces the same skeleton, a seed is a bookmark you can hand to a collaborator — they'll see the exact beats you expanded, not a stranger's version. And treat the output as scaffolding, not prose. The engine gives you load-bearing moments; the texture, dialogue and pacing are still yours to write, which is the point. Draft from the beats the same afternoon, while the arc is fresh in your head.
