What even is
AI?

Everyone uses it. Almost nobody can define it. In the next 28 minutes, you'll fix that — and probably know more about artificial intelligence than 95% of the people you'll meet this week.

Part 01 · The hook

Before breakfast, you've already used AI
at least eight times.

Tuesday, 7:43 AM. You haven't even brushed your teeth. Tap each moment below — the AI hiding in plain sight will reveal itself.

That's how many AI-powered moments you've discovered so far. Most people guess two, maybe three. The truth: artificial intelligence is already the invisible operating system of modern life.

Part 02 · The big idea

So — what is AI, really?

Three definitions, three lenses. Click each card to flip it and see the version that finally makes sense.

01 / Textbook
"The science of making machines do things that would require intelligence if done by humans."
Tap to translate →
In plain English
Computers doing smart-people stuff.
Recognizing faces. Understanding speech. Making decisions. Things a 5-year-old can do effortlessly — but were nearly impossible for computers until recently.
02 / Practical
"Software that improves at a task by learning from examples instead of being explicitly programmed."
Tap to translate →
In plain English
Programs that figure things out.
Instead of writing rules ("if email contains 'Nigerian prince', mark as spam"), we show the computer millions of examples and let it find the pattern itself.
03 / Honest
"A moving target. Once a computer can do something, we stop calling it AI."

In plain English
It's complicated.
Spell-check was once AI. So was GPS routing. Now they're just "software." The frontier moves fast — which is exactly why this course exists.
Part 03 · The mental model

AI, ML, DL, GenAI —
Russian nesting dolls.

These terms get thrown around like they're interchangeable. They're not. Hover or click each ring to see how they fit together.

The biggest circle

Artificial Intelligence

The whole umbrella. Any technique that makes machines act "smart" — including old-school rule-based systems that don't learn anything. Chess engines from 1980, your thermostat's logic, modern chatbots — all AI.

Part 04 · The spectrum

What we have vs. what we imagine.

Every AI you've ever used is "narrow." Every AI in a sci-fi movie is "general." Understanding the difference is the most important distinction in this entire course.

Real · Everywhere

Narrow AI

Brilliant at one thing. Useless at everything else.

General AI (AGI)

As capable as a human at any intellectual task.

Part 05 · The story

From a 1950 thought experiment
to your phone, today.

AI isn't new. It's been quietly evolving for 75 years through three winters, several false dawns, and a handful of moments that changed everything. Scroll the timeline →

1950

The Turing Test

Alan Turing asks: "Can machines think?" Proposes a test that still haunts AI 75 years later.

1956

AI is born

At Dartmouth College, a summer workshop names the field "Artificial Intelligence." Founders predicted human-level AI by 1970. Oops.

1966

ELIZA, the first chatbot

A rule-based psychotherapist that fooled real people — using nothing but pattern matching.

1997

Deep Blue beats Kasparov

IBM's chess machine defeats the world champion. Chess, supposedly the pinnacle of human reasoning, falls.

2011

Watson wins Jeopardy!

IBM's Watson dominates human champions. Natural language is no longer safe ground.

2012

The deep learning earthquake

AlexNet shatters image-recognition records using neural networks and GPUs. Modern AI begins.

2016

AlphaGo defeats Lee Sedol

DeepMind's AI conquers Go — a game with more possible positions than atoms in the universe.

2017

"Attention is all you need"

Google researchers publish the Transformer paper. Every modern chatbot you know was born here.

2022

ChatGPT changes everything

100 million users in 2 months. The fastest-growing consumer product in history.

2024+

The age of agents

AI stops just answering. It starts doing — booking, coding, researching, deciding. We're here.

Part 06 · Knowledge check

Five quick questions.
No pressure.

Wrong answers don't hurt your grade — they explain themselves. Try to beat 4/5.

You now understand AI
better than yesterday.

You learned the difference between AI, ML, DL and GenAI. You can spot narrow versus general AI. You know the timeline. That's a solid foundation — and we're just getting started.

How machines actually "learn"

The single concept that powers every modern AI — explained with cats, dogs, and one beautifully simple visual.
