1
Generate. The big red button opens the Mystery Generator. Pick one of 34 worlds or type your own, shape the cast, scenes, traits, and difficulty, and copy one master prompt into any AI tool.
2
The logic agents. Paste the reply back and the app runs it through three agents: structure, logic, and story consistency. They prove that every innocent is cleared by a clue, no clue touches the culprit, and exactly one name survives the chain. Anything broken produces a fix prompt you paste back to the AI.
3
The book. The app lays the story across the pages: cast files with portrait frames, scenes with numbered clue callouts, an evidence board, a detective grid, a verdict page, and a sealed solution the app writes itself from the proven chain.
4
Portraits. Every character comes with a matched image prompt sharing one style block. Copy it, make the portrait in any image AI, upload it, and it lands inside that character's frame.
5
Design and export. Shape paper, margins, themes, and fonts on the right, manage pages on the left, and export a print-ready PDF, PNGs, or a ZIP with no branding anywhere on the output.
