He Never Called Himself a Writer. Amazon Pays Him Like One.

He wasn't a writer. He had no audience, no publishing experience and almost no money to invest. But he had a system. He spent more time researching what people were actually searching for on Amazon than he did writing — and that made all the difference. Using a combination of AI tools he published 12 nonfiction eBooks in three months. The first month he made €70. By month three he was making €200 and climbing. Not life-changing yet — but the catalog was compounding and he was just getting started.

Time to first dollar: First sale within days of listing his first book.

Step 1 — Research before you write a single word Go to Amazon and type a topic into the search bar. Look at the autocomplete suggestions — those are real searches from real people. Find topics with consistent demand but thin competition. Tools like Publisher Rocket ($97 one-time) can show you exactly how many people search for a topic monthly. Skip this step and you're guessing.

Step 2 — Build your knowledge base with AI Once you have your topic use NotebookLM — Google's free research tool — to upload quality sources and synthesize them into a structured knowledge base. This becomes the foundation your book is built on. It takes an hour and produces dramatically better content than asking ChatGPT to write from scratch.

Step 3 — Draft with AI Take your knowledge base into Claude and prompt it chapter by chapter: "Using this research, write chapter one of a book about [topic] for [audience]. Make it practical, specific and genuinely useful." Edit each chapter for accuracy and voice. A 30,000-word book takes roughly a weekend this way.

Step 4 — Format and publish Use Reedsy Book Editor — free — to format your manuscript professionally. Design your cover in Canva. Publish on Amazon KDP. The whole process from finished manuscript to live listing takes about two hours.

Step 5 — Build the catalog One book is a lottery ticket. Twelve books is a system. Publish consistently — one new book every two to three weeks — and older books keep earning while new ones launch. The income compounds across the catalog over time.

At €3 royalty per book — a catalog of 12 books each selling 5 copies a day is €1,800/month. At 20 books each selling 10 copies a day that's €6,000/month. The math improves with every book you add. Most successful KDP publishers treat it like a portfolio — more titles, more passive income.

One book is a lottery ticket. Twelve books is a system. The income didn't come from any single title — it came from building something that compounded over time.
