WHY BRILLIANT WORKS

- One-on-one learning for all 
Private tutoring is the most effective way to learn, but it’s expensive, hard to schedule, and out of reach for most families. Brilliant’s tutor works with you one-on-one, every single day, for a fraction of the cost. No scheduling. No waiting. Just learning. 

- Like someone sitting next to you
Brilliant’s tutor can see what’s on your screen and react in real time, from highlighting parts of a problem to creating visualizations that bring hard concepts to life.

- Expert-crafted curriculum
Every course is crafted by our team of human experts from top institutions around the world. And with new and updated courses added every month, there’s always something new to explore.

- Learning that adapts to you
Brilliant’s tutor personalizes your experience in real time, adjusting to your skill level, filling gaps before they become problems, and helping you build confidence as you go.

- Build true problem-solving skills
Brilliant doesn’t give you answers. It guides you through problems and to your own a-ha moments. So while you’re learning, you’re also building critical thinking and analytical skills – and having fun.
