Learn to think

Brilliant replaces lecture videos with hands-on, interactive lessons. It’s a better (and more fun) way to learn.

Get started

Learn key ideas through problem solving

Brilliant helps you see concepts visually and interact with them, and poses questions that get you to think. Our courses show you that math, science, and computer science are – at their core – a way of thinking.

Learn to think like a scientist

All of our courses are crafted by award-winning teachers, researchers, and professionals from MIT, Caltech, Duke, Microsoft, Google, and more, with these principles of learning in mind.


Questions and storytelling that cultivate natural curiosity are better than the threat of a test.

Freedom to fail

The best learners allow themselves to make many mistakes along their journey.

Active learning

Research shows that interactive problem solving is more effective than watching lectures.
