Start your cozy mystery
A cozy mystery needs a charming sleuth, a tight-knit setting and a puzzle that plays fair. Pick a pack (a small-town shop sleuth, or a sleuth with a pet sidekick) and a setting, and Penwrite builds the crime, a detective, a sidekick and suspects with their own wants and wounds, plus a clue plan that seeds a red herring and the real answer.
The crime and the clue plan go into the Codex, so the AI knows the solution while it drafts and the reveal still works on the last page.

A fair-play clue plan
The real clues, a red herring and the culprit are planned before chapter one, so the solution holds up.
Suspects with motives
Each suspect gets a want and a wound in the Codex, so motives come from character rather than convenience.
Series-ready
Cozy readers love series; Penwrite can start book two in the same town with the same cast.
Step by step
- 1
Pick a genre and pack

Optional: your protagonist’s name, a setting and a one-line twist, plus the tone (and heat level for romance).
- 3
Get the foundations
A premise, a Story Bible, the cast with wants and wounds, a setting and key lore, streamed in about 30 seconds.
- 4
Review the outline
Five opening chapters built on your trope’s beats. Rename, reorder, regenerate or cut anything before you start.
- 5

You land in the editor with the Draft panel open; one click drafts the opening scene for you to keep, redo or rewrite.

Tips for your cozy mystery opening
- A distinctive hobby or shop for your sleuth gives the series its hook.
- Keep violence off the page; cozy packs set a clean heat level and a gentle or witty tone for the AI.
Frequently asked
Will the mystery stay consistent across the book?
Yes. Clues, suspects and timelines live in the Codex and Book Memory, which the AI checks on every generation, and the consistency checker flags contradictions.
Can I turn it into a series?
Yes. “Write the next book” starts a sequel that carries over the cast and the town.
Does it write the whole book?
No. It gives you a running start (foundations, a five-chapter outline and chapter one ready to draft), then you write with Penwrite’s AI alongside you.
Which plans include it?
Every plan, including Free and the Pro trial; it never uses a book credit. Generating counts toward your monthly AI words like any other drafting, and the new book counts toward your plan’s project limit.
