Cohort courses

Learn to codefor the agentic world.

You won't write much syntax — nobody does now. You'll drive an agent, and understand everything it hands back.

Nothing to install

No subscription, no API key. Open a tab and build.

The agent is ours

We host it. We pay for it. You just use it.

A mentor watching

Someone who watches you work, and reaches you first.

Tested, not vouched for

Your app runs and does the thing, or you haven't finished.

The problem

There are three ways to build now.two of them are dead ends.

You built less than they did

One of them ships things it can’t explain. The other explains things it never shipped. The job asks for both.

How a course works

Understand every piece of an app.
And how they talk to each other.

What a database actually is. How your page reaches it. What breaks when it can’t.

Lessons 1–3

The page

What people see. Headings, layout, type, colour.

Lesson 4

Your app

What happens when they press the button.

Lesson 5

The database

What it still knows tomorrow. Without one, everything vanishes when you close the tab.

Lesson 6

The internet

A URL you can send to someone.

The mentors

Mentors who have shipped real things.with an agent, for thousands of hours.

They’ve shipped real software and broken it at three in the morning. They aren’t teaching a theory of how this works — they’re teaching what it cost them to find out.

They see everything you build

Every prompt, every file, every failed check. Not a submission at the end — the work, as you do it.

They reach you first

You never have to put your hand up. If you’ve been stuck ten minutes, they already know.

They tell you what you’ll be asked

They go through what you shipped the way an interviewer will.

Priya · mentorYour preview’s been broken for ten minutes. You’ve got two things called Home in page.tsx — the icon and the component. Rename one of them.

What you leave with

Real apps, shipped.and you understand every one.

Live, at their own URLs. Open one in the interview and talk them through every decision — because you made them.
