Short version: you are buying a digital book. If it is not worth what you paid, ask for your money back within 30 days and you get it, no argument.
WTF Is AI is a digital book delivered as EPUB and PDF, and where offered, a printed edition. Buying it gives you a personal licence to read it and use the prompts inside it in your own work and business, for as long as you like.
Quoting a short passage with credit, or using the prompts in your own business, is fine and encouraged.
30 days from purchase, no questions asked. Email eking.pt@gmail.com with the address you bought with and I will refund it. You keep the file, because taking it back is theatre.
It is educational. It is not financial, legal, tax or investment advice, and it is not a business opportunity. The income models described are illustrative and no earnings of any kind are promised, implied or guaranteed. What you make from applying any of it depends entirely on you, your market and your circumstances. Where a decision has legal or financial consequences, take advice from someone qualified in your country.
The tools described change constantly. Prices, model names and features were correct when the book was published and will move. Verify anything that matters before relying on it, exactly as the book tells you to.
To the extent the law allows, I am not liable for losses arising from decisions you take after reading this book. Nothing here removes rights you have under consumer law where you live.
Everything goes to eking.pt@gmail.com and I answer it myself.
Note for the publisher: have this reviewed by someone qualified before you run paid traffic at scale, and align the refund wording with whatever your payment provider actually enforces.
