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.

Really fun little app, let's you stretch your brain a little while not being too intense. I feel like if I rush I won't get the answers right so it kinda slows me down and helps me think. My only 'complaint' is that the number of free lessons for the day is pretty small. But I guess if my only issue is I wanna do more that's kinda also a compliment.

I am truly addicted to this app. I understand that this is an educational app, but I cannot go a day without it. Those first couple of days were so intoxicating as you were rewarded after every lesson, you were given points to compete against others, & you were gifted the ever addicting, "streak." Now, even after 7 months, I get a little rush from the ring after completing each lesson, as if I were a pavlovian mutt. However, there are days when I forget, but Koji is right there to reel me back.

This app really makes learning fun! I picked it up mainly to relearn all the algebra I forgot in highschool so I could in turn learn more interesting subjects. the methods are very engaging and I feel like I'm learning more quickly than I did back in school and I'm having an easier time grasping the concepts. I've branched out into other topics the app covers and I'm having just as much fun with them too 😁
