Learn how AI
actually works

Not the hype, not the doom, not a 40-minute video that tells you AI is "a game changer" and stops there. Four short modules where you do something with your hands and come out understanding the thing — including why it lies to you and how to stop it.

No account. Nothing to install. Works on your phone.

You'll understand what's really happening

One idea explains nearly every strange thing AI does. You'll have it in about 60 seconds.

You'll write prompts that work

The five levers, and the one almost nobody pulls. This is most of the gap between people who rate AI and people who don't.

You'll know what to build first

Understanding AI and having built something with it are different things. By the end you'll know which one you're missing.

And finish any one module — not all four — and you've earned $20 off my build-it pack. That's the deal, stated up front.

The 60-second version

Three things. If you only read this far, you'll still be ahead of most people.

01

It's autocomplete with a library card

When you ask an AI something, it isn't looking up an answer. It's predicting what text should come next, one chunk at a time, based on patterns it absorbed from an enormous amount of writing. That's it. That one sentence explains about 90% of everything weird you've seen AI do - and once you've got it, the rest of this page is easy.

02

Which is why it can be confidently wrong

It has no idea whether it's right. It's producing the most plausible-looking next words, and plausible-looking is not the same as true. So when it invents a statistic or a source, that isn't a glitch they'll patch out - it's what prediction looks like when the pattern runs out and there's nothing solid underneath. Fluent does not mean correct.

03

And why your wording changes everything

If the output depends on patterns in your input, then your input is the steering wheel. Same model, same question, wildly different answers depending on how you frame it. Most people who think AI is underwhelming are writing three-word questions. The people getting remarkable results are writing briefs.

Your prompt is split into tokens, the model predicts the most likely next token, repeatedly, and those predictions become the answer you read.Your promptwordsTokenschunks of textPredictionwhat comes nextThe answerone chunk at a time
No lookup step anywhere in that chain. That's the whole reason it can be wrong and sound certain.

The ten words that unlock every AI conversation

Most AI writing is impenetrable for one silly reason: ten or so words are used constantly and explained never. Tap each one. That is the whole module.

What makes a prompt actually work

Five levers. Most people pull one — the task — and wonder why the output is generic. You're about to practise all five.

  1. 01

    Role

    Tell it who to be. This quietly sets vocabulary, assumptions and depth.

    “You are a conversion copywriter who writes for small e-commerce brands.”

  2. 02

    Task

    One concrete job, stated plainly. Not a topic - an instruction.

    “Write three product description options for the item below.”

  3. 03

    Context

    Everything it cannot possibly know. This is the lever most people skip entirely.

    “The product is a £40 refillable candle. Buyers are 30-45, care about waste, and have never heard of us.”

  4. 04

    Constraints

    The boundaries. Length, tone, what to avoid, what must appear.

    “Under 60 words each. No exclamation marks, no "elevate", no "unleash". Mention the refill once.”

  5. 05

    Format

    The exact shape you want back, so you can use it without reformatting.

    “Return a numbered list. After each option, one line on who it is aimed at.”

The prompt lab

Five real jobs. For each one you'll see the prompt most people write, then three rewrites — pick the strongest. You get told why either way, and getting it wrong teaches you more than getting it right.

Spot the AI mistake

Five answers that all look completely reasonable. Some are fine. Some are quietly wrong. Learning to feel the difference is the single habit that separates people who use AI well from people who get caught out by it.

0 of 5 judged
01

You asked How many small businesses fail in their first year?

AI answered According to a 2023 Harvard Business Review study, 47.3% of small businesses fail within their first twelve months, with undercapitalisation cited as the primary factor in 61% of cases.

What should you do with this answer?
02

You asked I sell at £45 and each unit costs me £18. How many do I need to sell to make £3,000 profit?

AI answered Your profit per unit is £45 − £18 = £27. To reach £3,000 in profit you would need to sell about 90 units, which works out to £4,050 in total revenue.

What should you do with this answer?
03

You asked What is the best way to deploy a small site for free?

AI answered Heroku has a generous free tier that is ideal for small projects - you can deploy straight from GitHub at no cost, which makes it the standard choice for side projects.

What should you do with this answer?
04

You asked Can you point me to the documentation for this?

AI answered Yes - the official guide covers this in detail at https://docs.example.dev/v4/guides/deployment-best-practices, under "Configuring custom domains".

What should you do with this answer?
05

You asked Can you make this sentence clearer? "We are currently in the process of undertaking a review of our pricing structure."

AI answered "We are reviewing our pricing." Everything else in the original was padding - "currently", "in the process of undertaking" and "structure" all restate the verb or add nothing.

The check

Eight questions, one at a time. You'll get an explanation for every single one — that's the actual point, the score is just scaffolding.

1 / 8
So what now?

You understand it. You still haven't built anything with it.

That's not a criticism — it's just where almost everybody stops. And the honest truth is that the distance between understanding AI and having something real, live on the internet, with your name on it, is much shorter than it looks. It's a weekend.

The part nobody teaches is the boring middle bit: deploying. Every tutorial builds something beautiful on your laptop and stops. That's the gap where most AI projects quietly die, and it's the gap my pack exists to close — two step-by-step guides that get you from nothing to a real site on your own domain, plus a call with me for the moment you get stuck.

On cost, so there's no mystery: a domain is about $10 a year and the hosting I teach is free. The pack is $97 $77 once you've finished a module here.

Questions

Before you start

Is this actually free?

Yes, all of it. No account, no email required, no trial. I wrote it because most "learn AI" content is either a sales pitch in disguise or so abstract you cannot do anything with it afterwards. If you finish and feel like building something with me, there is a paid pack - but you owe me nothing for this.

Do I need to sign up or install anything?

No. Everything runs in this page, in your browser. Your progress is saved on your own device so you can close the tab and come back - it never leaves your machine unless you choose to email yourself your results at the end.

How long does it take?

About 15-20 minutes for all four modules, and you do not have to do them in order or all in one sitting. Finishing any single one already earns you the discount.

I scored badly. Am I too late to learn this?

Not even slightly, and a low score is genuinely not a problem - most of the value here is in the explanations, not the number. Everyone confident about AI today was clueless about it recently; the field is about three years old in its current form. You are not behind, you are early. And the discount does not depend on your score.

What is the $97 thing you keep mentioning?

A two-guide pack that takes you from nothing to a real website, live on your own domain, plus a 1-on-1 call with me for when you get stuck. It is the practical follow-on from this page: you now understand AI, that teaches you to ship something with it. Finishing a module here takes $20 off.
