To learn anything, you have to start somewhere.

juststart is that first step. Pick what you want to learn and you get a clear path, the best free material in order, and a first lesson you can finish today.

Take the first step

Most people never start. Here's what usually stops them.

“I don't know where to begin.”: Every course is one path, in order. Lesson 1 tells you exactly what to do first.
“There's too much out there.”: Each lesson points to the best free material for that step, from universities and people who do the work, and skips the rest.
“I'm not ready yet.”: You don't need to be. Courses start from the basics and assume nothing.
“I'll lose track.”: Mark lessons done, keep notes as you go, and pick up exactly where you left off.

How every course works

1
Take the first step
A small lesson you can finish in one sitting. Getting started matters more than getting it perfect.
2
Follow the path
Lessons build on each other, with practice at every step so you learn by doing, not only by watching.
3
Make something of your own
Each course ends with a project you build yourself. That's how you know you've really learned it.

First course

AI from first principles

Using AI isn't the same as understanding it.

Right now almost everyone is trying AI apps and sharing what they made with them. That's a good start, and it's where most people stop.

If you want a future in AI, using the apps isn't enough. Everyone else can use them too, so the advantage fades fast. What lasts is knowing what's underneath: the maths, the code, how a model is trained and why it behaves the way it does.

This course takes you there, all the way to training a model of your own. And if you only get partway, the attempt will still teach you more than any app can.
