About this app

Brilliant helps you excel in math and computer science with visual, interactive learning and personalized practice. Whether you’re a student or lifelong learner, Brilliant is designed to strengthen your STEM skills and turn you into a more confident thinker and problem solver.

Brilliant believes that everyone is a “math person”– it’s the way we learn math that can feel confusing. Here, you don’t memorize formulas. You explore concepts hands-on until they make sense. Brilliant guides you to real “aha” moments, helping you build the problem-solving skills, logic, and mathematical intuition needed for success in school, careers, and technical fields.

Our award-winning team of teachers and researchers from MIT, Harvard, Stanford, Microsoft, Google, and more has built a world-class library of STEM courses. Learn everything from foundational math and algebra to college-level calculus, Python, programming, computer science, AI, neural networks, algorithms, data analysis, physics, and quantum computing. Join over 10 million learners using Brilliant’s interactive lessons to master math, computer science, and more.

WHY BRILLIANT WORKS

- Reach serious learning goals
Brilliant teaches through active problem solving – a method shown to be far more effective than passive learning like videos or lectures. Interactive problems, motivating challenges, and real-time feedback help you understand math, coding, and science concepts.

- Learning that adapts to you
Brilliant personalizes your experience, tailoring practice sets to your skill level and helping you progress at the right pace. Smart, adaptive learning tools reinforce core skills and prepare you for more advanced STEM topics.

- Build true problem-solving skills
Brilliant doesn’t give you answers – it gives just enough guidance to help you reason through problems yourself. So while you learn, you build the critical thinking and analytical skills needed for real-world problem solving.

- A massive library of expert-crafted content
With new and updated courses added every month, there’s always something to explore in algebra, geometry, calculus, statistics, algorithms, Python, electrical engineering, data analysis, and more. Every course is crafted by human experts – not AI.

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.

Really fun way to learn things! With the app, you get two lessons a day for free, unless you'd like to upgrade to unlimited. I've been learning scientific thinking, and it's helped me learn some basics of stuff all over that I wouldn't have thought to learn about. It's presented in an easy to understand way, and it's all interactive - which is a must for me. If I had the money, I would honestly pay for the subscription, but for now I've actually been pretty satisfied with just two lessons a day.

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 😁
