1Guess first
How many numbers are inside GPT-3?
Each is a setting the model learned, called a parameter. Drag the marker to your guess, then lock it in.

See how AI actually works.
ChatGPT grew from one small idea, drawn on paper in 1958. You can move it with one finger.
Every lesson starts with a picture you push on. The words come after the picture, and the math comes after the words.
Drag the blue handle until every dot agrees.

Four boards from the lessons, live on this page
The same boards the lessons use. Each one takes about half a minute, and nothing needs reading first.
2Turn a knob
Why a chatbot never says the same thing twice
A model is finishing “The capital of France is”. Turn up the temperature until Paris gets 50% to 70% of the chances, while pizza stays under 5%.

3Cut it up
A model never sees letters
It reads words in pieces it has seen many times. Cut “unbelievable” into three: a start, a middle and an end.

How a model learns: small steps downhill
The dot is a model's error. Pick a step size and press Run. Reach the bottom in 20 steps without jumping past it.

How a lesson teaches
An idea is yours once you have felt it, guessed it, run it, and seen where it breaks.
Push on it
Drag a weight and watch the line move. Every picture in a lesson answers your hand.
Guess first
We ask what you think the curve looks like before we draw it. A wrong guess is the one you remember.
Run the code
Train a real model right on your device, with no Python, no install and no cloud bill.
Pick your depth
Story, Build or Deep. No code and no formulas unless you want them, and they are always one tap away.
Arabic, written not translated
Native phrasing, right-to-left layout and Arabic-Indic digits.
A tutor that knows the lessons
Ask about the step you are on. It answers with the same pictures you just used.
From one neuron to agents
One road in three stages. The level test finds where you join it.
Stage 1 · Beginner
How Machines Learn
From one neuron to a network you train yourself.
No background needed. By the end you can explain how a machine learns from examples, and train a small neural network.

Stage 2 · Intermediate
Inside the Models
Open up the networks that see, remember and write.
You pick up the working tools and look inside the transformer. By the end you know what happens inside a chat model.

How it goes
Find your level
An eight-minute test finds what you already know and skips it.
Follow the road
One idea per screen. A lesson takes five to twelve minutes.
Prove it
Quizzes as you go, then a chapter exam. Pass it and the chapter is yours.
Who this is for
Curious
You keep reading about AI and still feel one step behind.
Developers
You ship features with model APIs and want to know what is inside.
Students
You have the math and want to see where it lands.
Researchers
You want to read papers and reproduce the result yourself.
Questions people ask
No. Math shows up after the picture, and every symbol is explained the first time it appears.
No. Code steps run on their own. You can read, change one number, and run again.
No. Each lesson is written twice. Technical terms give the Arabic word with the English in brackets the first time.
$10 a month, in US dollars. One plan. Cancel any time from Settings, and you keep Premium until the end of the month you paid for. All sales are final.
Yes. Masfofah runs on the web, on iPhone and on Android. With Premium, your progress follows you from one to the other.
A lesson takes five to twelve minutes. Do one a day and you finish a chapter in about two weeks. The level test lets you skip what you already know.
Anyone thirteen or older who wants to know what is going on inside AI. You do not need a background in it.
