Created by Søren Jordansen, Cozy Co-Author is a structured AI co-writing system designed to help authors plan, draft and complete full-length cozy fantasy novels.
The system uses three core files: a detailed cozy-fantasy framework, a style pack for maintaining consistent prose and a guided setup prompt. You answer a series of creative questions, and the system helps build planning documents such as your world and story bibles, character profiles, chapter outline and an ongoing story-state record.
You then work through the novel chapter by chapter using ChatGPT or Claude, reviewing the writing, giving direction and making the creative decisions as the story develops. The story-state process is designed to help maintain characters, events and continuity across a full novel or connected series.
A 29-module training course also covers editing, formatting, book covers, publishing, promotion and series development.
Cozy Co-Author has been tested by Love My Ebooks. Authors should still carefully revise, fact-check and personalise every manuscript before publishing. A suitable paid ChatGPT or Claude plan may be required.
