You have felt it. The pull to write a novel. The idea that actually excites you. Then the cursor blinking on an empty document and nothing coming out.
Most people who want to write a novel never finish one. Not because they lack creativity. Because they lack a system. Chapter seven arrives, momentum dies, and the draft goes cold in a downloads folder somewhere.
AI was supposed to fix this. And for a while, it seemed like it might. Then you tried it. The result was flat, padded, and obviously machine-written the kind of prose that earns one-star reviews and poisons a pen name before it gets started.
Cozy Co-Author is a different animal. It is not a prompt. It is not a template. It is a structured two-file system built for Claude that handles genre rules, prose discipline, voice consistency, plot continuity, and planning architecture.
The creator, Søren Jordansen, built it to solve his own problem. He wanted to publish cozy fantasy novels on Kindle Unlimited without spending six months on a single manuscript.

Product Overview: What Is Cozy Co-Author?
Cozy Co-Author is a two-file AI writing system built for Claude. It is designed to help anyone — writer or not plan, write, and publish a cozy fantasy novel for Amazon KDP and Kindle Unlimited.
The product was created by Søren Jordansen, also known as The Copy Viking.
The system is built on a core insight: cozy fantasy readers live inside Kindle Unlimited, they binge series, and Amazon pays per page read not per borrow.
Quick Summary: Two files. A guided 14-question setup. Claude writes chapter by chapter. A 23-module training course takes you from finished manuscript to live Amazon listing.
Key Features of Cozy Co-Author
Two-File AI Writing System
The entire framework lives in two files. You paste both into a Claude Project. No apps to install, no accounts to create beyond Claude itself.
14-Step Guided Story Setup
Setup is a guided 14-question process. At every step, Claude offers multiple options with explanations and recommendations.
Structured Planning Documents
The setup process generates a full pre-writing architecture:
- Story Bible
- Character Profiles
- Chapter Outline
- World-Building Details
- Continuity Structure
Cozy Fantasy Genre Framework
The framework is built specifically for cozy fantasy warmth over darkness, character over plot mechanics, and comfort as the genre’s core promise.
Nine Voice Profiles
Inside the framework are nine distinct voice profiles to give Claude tonal range within the genre.
Anti-AI Prose Controls
The framework includes banned-word lists, anti-AI prose rules, and instructions to avoid common AI writing failures.
Chapter-by-Chapter Writing Flow
Claude writes chapter by chapter instead of dumping an entire draft in one session.
23-Module Training Course
The system includes a complete guided course covering:
- Genre strategy
- Story planning
- Editing
- Formatting
- KDP publishing
- Author profiles
- Series-building
