Genre-specific catalyst, dilemma, stake, and plot-beat libraries are combined with your protagonist, goal, setting, obstacle, theme, audience, and ending direction. Six distinct catalysts are selected without replacement. This is a deterministic, browser-local guided generator, not a language model. Identical inputs and variation number reproduce the same draft. No model inference, fact checking, originality clearance, or performance prediction is performed. Review and edit before use.
Use theme as a question, not a lecture

GOOD TO KNOW
A few useful answers.
Are the six ideas guaranteed to be original?
No. They recombine a finite set of story structures with your inputs. Treat them as prompts, research similar works, and develop your own expression.
Does the tool write a full novel?
No. Each direction includes a premise, thematic question, four story beats, and rough title seeds for further writing.

The output includes an audience lens for agency, complexity, and peril. It cannot certify age appropriateness; you still need to evaluate the actual manuscript.
Why choose an ending now?
An ending direction helps you test what the central choice costs. It is a planning constraint you can change later, not a fixed plot prescription.
