Before we talk about the book
Have any of these thoughts crossed your mind?
Check the ones that apply to you. They stay on your screen only: nothing is sent or saved.
If you checked at least one, this book was written for you.
None of this is a lack of ability. Many people get frustrated because they talk to AI as if they were chatting with a friend, and nobody explained that it needs something else: clarity.
You're not behind. You're starting in the right place.
32% of internet users in Brazil already use generative AI, about 50 million people. That is a lot of people. It also means most of them are still at the beginning, just like you.

You don't need to know everything to get started. You need a good starting point.
What makes this book different

How to check what AI delivers, protect your data, and recognize scams. The final responsibility is always yours.
And why you can trust it
It says on the cover how it was made
“Content made with AI (and with my best prompts).” The book itself is an open demonstration of what it teaches.
It was researched and fact-checked
There were 8 topic research rounds and 8 fact-checks before the final text. Prices and laws come with dates.
It admits what aged
The 2nd edition opens by telling what changed, including two tools recommended in the 1st edition that no longer exist.
It tells you what AI doesn't do
It has a list of what never to do, explains hallucinations, and shows real cases where trusting too much was costly.

Before
What's the best cell phone plan?
Promptizer Ray
Search the web for the postpaid plans from the 3 largest carriers in Brazil available today in my city, [city name]. Build a table with price, data allowance, and benefits. Cite the official link for each plan and let me know if any information is not confirmed on the carrier’s website.
Same subject, a different answer. And the book’s rule applies here too: even with sources, check the links.

Who wrote it
Tiago Santos
More than 20 years in communications, digital marketing, technology, and project management. Founder of Sprintum, he has led large-scale digital projects and today works with processes, automation, and Artificial Intelligence.
Right in the introduction, he warns: “You will not become an expert.” What you take away is what matters most at the start: the essentials to talk about AI with confidence and choose the best way to make it work for you.
Is this book for you? Let's be honest.
It's for you if you
- Have never used AI, or have used it little, and want to understand it before deciding anything.
- Work in any field, from education and health care to administration and crafts.
- Have already tried it, got generic answers, and suspect there is a better way to ask.
- Want to know what makes sense before paying for a long course or an expensive tool.
It's not for you if you
- Already automate tasks and want to talk about APIs. This is not your book yet.
- Want to become an expert. The book gives you the foundation, and says so right in the introduction.
- Are looking for a quick-income formula or a job promise. There is none here.
- Want AI to decide for you. The judgment is still yours.
2nd edition · November 2026
In 14 months, AI changed. The book changed with it.
The 1st edition came out in August 2025. This one was rebuilt for what exists today.
Agents
AI that opens the browser, clicks, and fills things in for you, and how far you can trust it.
Apps without coding
What so-called vibe coding can already do and what it still can’t.
New chapter on terms
8 new words explained in plain language.
Two new prompt tips
How to use projects, memory, reasoning, and deep research.
Scams and deepfakes
Cloned voices, silent calls, and what to agree on with your family.
Tools reviewed
Out went the ones that ended, like DALL·E and Sora. In came the ones that matter in 2026.
Do the math
Learning on your own has a price too. It just doesn't show up on the bill.
Going by trial and error alone
It costs time. Every generic answer turns into rework, and no one warns you when the AI made up a fact.
Subscribing too soon
Entry-level paid plans charge a monthly fee; chapter 5 lists their October 2026 prices. To learn and experiment, the free plan usually does the job.
Starting with a long course
It can be great, once you know what you need. Understanding the basics first helps you choose better.

Frequently asked questions
Before you buy
Do I need to know anything about technology?
No. The book was written for people who are just starting out. Every term is explained before it is used.
Do I need to pay for any AI?
Not to get started. Free plans do quite a lot, and the book shows when they are enough and when it is worth paying. The rule is simple: start by testing for free.
I already use ChatGPT. Is the book for me?
It is if you use it a little or get answers you have to redo. In that case, chapters 5 and 6 tend to be the most useful. If you already automate tasks and work with APIs, it will feel basic.
AI changes fast. Won't the book get outdated?
Tools change, and the book says so plainly. That is why it teaches fundamentals, which change much less, and keeps prices in a single dated table. This 2nd edition is from November 2026.
Can a book made with AI be trusted?
The author used AI and says so on the cover. The text went through research, fact-checking, and editing. And the book repeats what applies to any content: check anything important at the source.
Do I need to read it in order?
It's worth reading chapters 1 to 4 in order. Chapter 5 works as a reference: go straight to the field that interests you.
How do I access the Prompt Generator?
It's exclusive to buyers. Access is password-protected, and the password is inside the e-book.
What format do I get, and when?
In digital format, through Hotmart. Access is released right after payment is confirmed, and you can read it on your phone, tablet, or computer.
How does the guarantee work?
You have 7 days to read it calmly. If it doesn't make sense for you, request a refund within that period through Hotmart, and your money is returned.
Will this book give me an income or a job?
We don't promise that, and be wary of anyone who does. What the book offers is knowledge to use AI with more clarity and safety. What you do with it depends on your practice.
There is always a next step. Yours can be this one.
Start by understanding. Then experiment. You get the e-book, the Prompt Generator, and 7 days of guarantee to decide calmly.
