Sixty days to change your mind.
Full refund, no questions asked.

Digital eBook · 445 pages · 60 chapters · 100 prompt cards · 25 worked conversations · 6 worksheets
You open the box, type something, and get back a paragraph that is fluent, confident and not quite useful. So you close it again. Nothing was broken. You simply had no reason to be there.
A course would hand you sixty videos and a schedule. That is the wrong shape for this. You do not need to study AI on a Tuesday evening. You need to find the right page on the afternoon a confusing letter arrives.
So this is built like a reference book. Find the job. Read four pages. Get the thing done. Put it back on the shelf until the next time.
Why it is built this way
Nobody reads a dictionary cover to cover and nobody feels guilty about that. You open it when you hit a word. That is exactly the relationship this book is designed for.
Three months from now, an unfamiliar letter arrives, or a suspicious text, or a quote you cannot compare. You will not need to remember a lesson. You will need to find the page. That is what you are buying.
Get the encyclopedia · $27Find the job, not the jargon
Each chapter takes one job from start to finished result — including the moment the first answer is wrong and what you say to fix it.
Chapter 23
Separate the required action, the deadline, the conditions and the exceptions — and see which details the assistant quietly left out.
Chapters 22 & 31
Draft the difficult email while keeping your own facts, your own tone and your own intentions intact.
Chapters 28 & 59
Find the real total, keep the missing terms visible, and get a better follow-up question to ask.
Chapters 33 & 34
Turn a memory into a first page without letting AI invent the parts you never told it.
Chapters 55–57
Messy notes into clear next steps, your first understandable spreadsheet, an honest work sample.
Chapters 45–47
A convincing message is a claim, not a fact. Learn the verification route that does not rely on the message itself.
The complete contents
Thirteen parts. Every chapter is a self-contained job with a worked example, a correction and a check. Read the list and see whether this is the reference you need.
The 100 prompt cards
Every card is built the same way: the job it is for, the request to send, the follow-up that improves it, what a good result actually looks like, and the mistake to check for before you act on it.
Use this for a suitable, anonymized excerpt from a notice, letter, or set of terms.
Use this for a bill or offer with several charges or changing prices.
Use this to record a photograph, place, event, or personal observation you are comfortable preserving.
Judge it before you buy it
Read an excerpt from Chapter 4: Your First Useful Conversation and get a feel for the teaching. Free to read, with no email required.
You do not need a perfect prompt for your first useful result. A prompt is simply what you send to the assistant: a question, an instruction or some material to work on. Begin with a task whose answer you can judge yourself. A short invitation is better practice than an investment decision because you already know what the invitation should say.
If you have not opened an assistant yet, use your browser to go directly to https://chatgpt.com. Check the address before entering information. Follow the account instructions shown by the official service if you choose to sign in. You can also use an official app, checking that its publisher is OpenAI. A browser is the program you use to visit websites; you do not need to install an additional app for the exercise.
Look for the box where you can type a message. Controls and sign-in options can change, so use the labels on your own screen. Click or tap inside the message box, enter the request below and use the visible send control. If something unexpected appears, stop and read it. Do not buy a subscription merely because an upgrade is offered.
ChatGPT has a free option. Features and usage limits vary, but ordinary text requests are a sensible starting point. This book's purchase does not include a subscription to ChatGPT or another AI service. You can learn the core method before deciding whether any paid feature would solve a problem you actually have.
Use the following fictional practice request. It contains no personal information and gives you a result you can inspect immediately.
Read the answer before sending another request. It includes the day, time, location and question. It has not invented an address or promised lunch. “Come over” implies the home setting naturally, although you can ask for “at my home” if that would be clearer.
Now improve one thing:
You may prefer the first version. That is allowed. AI is offering wording, not grading your taste. If the second version had changed Saturday to Sunday, you would correct the date before polishing the tone. The facts are the part you already know.
A draft in the chat has not invited anybody. To use it, select the text and copy it into your normal messaging or email app. “Copy” puts the selected text temporarily on your device's clipboard; “paste” inserts it where your cursor is next. Many assistants have a copy control near the answer. If you cannot find it, your device's usual text-selection method is enough.
Before sending a real invitation, replace the practice details with the arrangements you intend. Check the recipient, day and time. If the message needs an address, enter the correct one directly in your messaging app. You do not need to share it with the AI to learn how to write an invitation.
Save a version you like in a note if you expect to use the pattern again. Name the note after its purpose, such as “short invitation,” rather than “brilliant prompt.” Next time, update the facts. A saved pattern is a starting point, not a schedule that remains true forever.
If typing is uncomfortable, your device may offer speech-to-text, which turns spoken words into written text. Read the transcription before sending it, especially names, dates and numbers. Voice conversation is a separate feature in some assistants; you do not need it to dictate a message using your device's keyboard microphone.
The useful information in the invitation was the job, the facts, the limits and the desired form. That is the beginning of a reusable method. “Help me” leaves all four open. “Draft an invitation for Saturday, keep it short and do not add arrangements” gives the assistant a job with boundaries.
For another task, choose only the details that change the answer. A dinner request needs ingredients and equipment. A trip needs the destination, dates and your preferences. An explanation needs the thing you do not understand and the level at which to begin. You rarely need to supply your entire history.
You can use that pattern, but do not make filling it in a ceremony. The invitation worked without a technical vocabulary or an elaborate instruction to become an expert. You completed a conversation, checked the result and learned how to revise it. Chapter 6 will use those same moves for a more complicated brief, where facts and decisions arrive in pieces.
A useful first session ends with something you can use and a reason to trust the details you checked.

I had tried ChatGPT and honestly couldn’t see what all the fuss was about. Lots of words, very little help. This book showed me how much I was leaving out of my questions. Once I started explaining my actual situation and asking for a specific result, the answers improved enormously. Wish someone had explained that at the beginning.

The prompt cards are my favourite part. Like a dictionary, except I’m looking up how to ask for help. There’s usually something close to what I need, and changing the example is much easier than starting from nothing. I’ve gone back to the ones about letters and customer support calls several times already.

It’s the ordinary examples that sold me on actually using AI. A difficult letter. A complaint you keep postponing. Questions for an appointment. I’d heard plenty about how it was going to change the world, but I needed someone to explain where it fitted into my Tuesday.

Apparently you can tell it an answer is too vague and ask it to try again using your circumstances. I didn’t know that. I’d just been reading the disappointing answer and closing the window.

My daughter is lovely about helping me, but I don’t particularly enjoy needing help with every unfamiliar thing on my laptop. The section about getting assistance with the screen in front of you has been especially useful. I can ask for one step, do it, then ask for the next. I’m 74. I like being able to have a proper go myself.

The doctor’s appointment chapter was the first one I used. I normally remember my questions on the drive home, which isn’t much good. This helped me put my concerns in order and prepare questions about what to track and what happens next. I took a printed page with me. For once, I came out feeling I’d actually asked what I went in to ask.

I bought it to learn about AI and ended up writing about my father’s shop. The life story section suggests letting it ask you one question at a time. That suited me much better than sitting down to “write my memoirs,” which sounded far too grand. I started with what I remembered about opening up in the mornings. A few pages later, I realised I’d finally begun something I’d been putting off for years.

Comparing repair quotes! I would never have thought to use AI for that. The book showed me how to check what each one actually included and identify the questions I still needed to ask. Very useful.

Bought it for the practical stuff. Stayed up reading about recording the stories behind old photographs. There are people in our albums my grandchildren will never meet, and things about them only I remember. I’ve started putting those memories into words.
The complete digital edition
You are not renting access and you are not joining anything. You are buying four files that sit on your device and answer questions for as long as you own it.
This is not a Book. This is an Encyclopedia for AI.
One payment. Yours to keep for good. No subscription, no renewal, no account to cancel. The price returns to $99 after launch — and it will never be sold for less than it is today.
Get instant access · $27Read it. Try three chapters on real tasks. If it is not the reference you hoped for — for any reason, or for no reason you feel like explaining — email omar@decodesfuture.com within 60 days and you get every cent back. You keep the files. We do not ask why, and we do not make you justify it.
Be honest with yourself first
Before you decide
You need a phone, tablet or computer, an internet connection, and the ability to type a sentence. The book explains every unfamiliar word the first time it appears, starts with one small request, and shows you how to improve the answer. There is no coding anywhere in it.
Yes — that is the primary audience, and it shapes everything: adult language with nothing talked down to, larger readable type, examples from real life rather than from an office, and a pace you set yourself. Complete beginners of any age use the same lessons very happily.
No. Every core method in the book works on a free assistant account. Some image and file features have limits that change over time, and the book says so where it matters. This purchase does not include a subscription to any AI service — it is an independent guide, not affiliated with OpenAI, Google or Meta.
Four files, immediately: the 445-page PDF, an EPUB for e-readers and phones, a plain-text Markdown edition, and the Project Workbook with six worksheets. The 100 prompt cards and 25 worked conversations are inside the book. Download links appear on screen the moment payment clears and are emailed to you as well. You can re-download them whenever you like.
Because the free thing answers questions; it does not tell you which question to ask, what a good answer looks like, or how to catch a confident one that is wrong. That is what 445 organised pages, 100 tested prompt cards and 25 worked corrections give you. And you can read an excerpt on this page, free, before you decide whether that is worth $27.
This expanded website edition develops that book: revised lessons, clearer chapter titles, and six new chapters covering work projects and a personal reference system. Substantial material is shared between the two. If you already own the original, please read the additions above before buying — we would rather you kept your money than bought something you largely have.
No. It teaches you to organise information and prepare better questions for the qualified people who should actually answer them — and it shows you how to recognise when an answer needs verifying. In an emergency, contact local help directly rather than asking a chat.
No. One payment of $27 today. Nothing recurring, no trial that converts, no account that expires. The price returns to $99 after launch, but you will never be charged again for what you buy now.
Email omar@decodesfuture.com within 60 days and you get a full refund, no questions asked. You keep the files. We would rather have an honest refund than an unhappy reader.
