AI education has become expensive, which is most of why we exist. These are the best courses, lecture series and channels on the internet that charge nothing, each one checked so you don't hit a paywall three lessons in.
No cost at all. No card, no trial, no locked lessons.
All the teaching is free; only the optional certificate costs money.
Still free, but you'll need to make a login first.
We're not affiliated with any of these and we earn nothing from linking them. Prices and access do change, so if you find one that's gone behind a paywall, tell us and we'll pull it.
No maths, no coding. These assume you're starting from nothing, and they're right to.
The best free starting point that exists. Built for non-technical adults, translated into dozens of languages, and completely free including the certificate. Work through it at your own pace.
A short, official introduction to what generative AI is and how it differs from other machine learning. Good if you specifically want to understand the tools everyone's suddenly using.
Not a course, but a toy that teaches more than most courses. Train a model in your browser using your webcam in about ten minutes, and machine learning stops being abstract.
Free, no sign-up, and in some cases better than anything you could pay for.
The clearest visual explanation of how neural networks actually work that anyone has made. It does use maths, but it shows you the maths rather than assuming it.
A full beginner series covering how AI works, where it's used and what it gets wrong. Fast-paced, well made, and aimed squarely at people new to the subject.
MIT's actual deep learning course, lectures published free every year with slides and labs. Technical, but this is a real university course you are not paying for.
These expect a bit of comfort with computers, and some involve code. All still free.
Short, hands-on and entirely in your browser. You build a working model in the first hour, which is the fastest way to make the theory stick.
How large language models are built and used, from the people whose tools most of the industry runs on. Free, open, and genuinely current.
Famous for teaching top-down: you train a working model in lesson one, then learn why it worked. Needs some Python, but it's the friendliest serious course out there.
Real degree-level courses you can take for nothing. Only the certificate costs money, and you don't need it to learn.
Harvard's AI course, following the excellent CS50 tradition. Covers search, knowledge, optimisation and machine learning with real projects.
Andrew Ng's course, the one a huge share of the field started with. Choose "audit" on each course in the specialisation to take it at no cost.
Built for school-age learners and the people teaching them.
Free lessons and activities designed for classrooms, with teacher guides included. Genuinely usable with no technical background.
A collection of small browser experiments, from drawing games to sound and language toys, that show what AI can do. Brilliant with kids, and nothing to install.
Nothing in that category yet. Try another filter, or recommend a course you rate.
If something taught you well and cost you nothing, we'd like to put it in front of more people.
Our own guides and videos cover the same ground in minutes rather than weeks, a good place to start before committing to a full course.
