One path, from curious to capable

Each course takes 15–30 minutes and ends with a quiz or a build. Go in order or jump to what you need — your progress is saved on this device.

    How learning works here

    Built for people who learn by doing — students, career switchers and curious professionals.

    15 min

    Short, focused lessons

    Every course fits in a coffee break. Clear explanations first, then the technical depth for when you want it.

    Quiz

    Check, don't guess

    Interactive quizzes, drag-and-drop exercises and code challenges show you what stuck — and what to revisit.

    Build

    Leave with a portfolio

    Pro courses end in real projects: a classifier, a sentiment model, an LLM app. Things you can show an employer.

    Start free. Go Pro when you're hooked.

    The first four courses are free forever. Pro unlocks the other nine, the projects and your certificates. One-time payments — no subscription to cancel.

    Questions

    Do I need to know maths or programming?

    No. Course 0.5 teaches you enough Python to follow along, and every concept is explained in plain language before the technical version. If you can use a spreadsheet, you can start.

    Who is this for?

    Students (including motivated teens), career switchers and professionals who want to understand and use AI — not just read headlines about it.

    How long does it take?

    All 13 courses add up to about 5–6 hours of core content plus projects. Most learners do one course a day.

    Is it a subscription?

    No. Both Pro plans are one-time payments. The 12-month plan simply ends after a year; nothing renews automatically.

    Where is my progress stored?

    On your device (in your browser). We don't need your data to teach you. Pro access is tied to the email you pay with, so you can restore it on any device.

    Can I get a refund?

    If something doesn't work for you, write to us within 14 days and we'll sort it out. Details are in our terms.
