The problem

Sound familiar?

The idea dies at the developer quote

Quote: 80,000 DKK. Delivery: three months. 50% upfront. You walk away — not because the idea is bad, but because the path is too long, too expensive and too uncertain.

You cannot build it yourself

The calculator, the customer portal, the small internal tool — you know exactly what you want, but you do not write code. So it stays talk.

AI demos that never become anything

You have played with the AI tools, but nobody has shown you how to get from demo-play to something your customers can actually use — without amateur mistakes.

Questions & answers

No — and the book never claims you can. Landing pages, calculators, mini-CRMs, booking tools and internal dashboards: yes. Payment flows, sensitive customer data and multi-tenant SaaS: wait until you understand the security. The book teaches you exactly that distinction.

PDF — delivered by email instantly, plus a download page with both the English and Danish editions. The link works for 90 days and can always be refreshed.

No. Vibe coding means you describe, validate and steer — Replit Agent writes the code. Your role is the product manager's, not the programmer's. The book is written entirely without tech jargon.

A Replit account and a browser — nothing gets installed on your own computer. The book is written for Replit as of July 2026; features and prices change, so always verify against the provider's own pages.

Yes — consultants use it for demos, lead magnets and customer tools, and SMEs for internal dashboards and calculators. Write to us about volume licenses if several colleagues need it.

PS: The book does not promise that anyone can build anything — it teaches you what you can realistically build yourself, and when to hire a developer. According to the author, that last part is the most important.
