The tools this book teaches

The problem

Sound familiar?

Tasks take what they take

The report eats an afternoon. The proposal drags out. The presentation waits on Sunday evening. You work manually, patiently — and expensively in time.

You tried ChatGPT — and closed the tab

A question, an answer, an appreciative nod. Then back to doing the work by hand, the way you always have.

Every task starts from scratch

No standing prompts, no reuse, no assistant with your tone and your templates. You reinvent the method every single time.

Layer 1 — where the vast majority of the book's workflows live — works on every subscription, without installing anything. Layers 2 and 3 use add-ins and Custom GPTs, and the book is honest about what each layer requires and what is still on the way.

Yes. No technical background, no code. The book is a reference work for action: after the foundation you go straight to whichever program you're working in right now.

Yes — the workflow cards and Custom GPTs are made to be shared with colleagues, and the bridge plan can run as a shared 30-day program. Write to us about volume licenses if several colleagues need it.

The workflow-card prompts are in English — ready to paste, with [SQUARE BRACKETS] where you fill in your own details. Everything around them is in your edition's language.

PS: The most important sentence in the book: the bridge is not ChatGPT. The bridge is you plus ChatGPT plus the right prompt.
