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.

Amazing and interactive app
tanvi.patil
I’ve just started using Brilliant and it’s an amazing app! It breaks down concepts in an easy way, and I love how interactive the lessons are. Each story behind the lesson is super interesting, and is actually something you can use in real life (rather than the “x got 100 pineapples” questions we had in school 😂). It’s motivating and I love that it doesn’t have a time limit, or imposes any penalty on getting an answer wrong. Even the text boxes are encouraging. I learnt about the app from a TED-Ed video, and I’m so glad I came across it! Thank you so much for making a wonderful and accessible app like this!! Much love and gratitude ❤️✨
AMAZING APPPP
ٰlilith
i never usually rate apps, like never… unless deserved, i think i’ve played more than 200 games and only a few deserved 5 stars, and this app is one of them. not only is it educational, it’s also interactive. i’m learning things i never expected to even hear about, and things i’ve questioned before but didn’t feel like getting the answer for, it’s all here. it’s sad that i have to pay for some things but i understand, the developers deserve the money. 😼
Good but the Premium plan is bad
Ali the master rater
This is an excellent app to excel at math, CS, data analyzing and science, with interactive lessons to teach you in depth how to solve equations, to write programs etc., but you only get limited lessons per day, with the Free plan, while with Premium, you get infinite. The only problem with the upgrade plan is that it is not limited failure (like Duolingo, where there is 5 lives per day) but limited LEARNING. This is a big problem because it doesn’t make you push to make yourself better like Duolingo, but giving money to them, to learn more. This is a bit disappointing and I hope that Brilliant uses lives, not keys for the Free plan.
Developer Response
Thank you for taking the time to share this—it's great to hear you're enjoying the app and finding value across math, CS, and science. We also appreciate your thoughtful perspective on how the Free plan is structured. We understand your concern that limiting access to lessons can feel discouraging compared to systems that encourage continued practice through other mechanics. Feedback like this is really helpful, and we’ll make sure it’s shared with our team as we continue refining the learning experience.
