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.

The free version is a waste of time. The app keeps on promoting to pay for premium, which is quite expensive, and if you want to learn. Without it, you can do up to 2 lessons per day, and you can't skip basic lessons. There are so many basic lessons that you have to waste many days in order to reach a decent level where you get a bit of challenge.

Thanks for the feedback—we aim to provide meaningful learning even on the free plan, which offers 2 daily lessons to build steady progress. Premium unlocks unlimited access, but we understand your concerns and will share this with the team. We appreciate you giving Brilliant a try.

The app makes learning fun , one aspect is it should allow at least 3-5 free lessons everyday as some can genuinely not afford the premium and learning feels like only available to those who can pay and there can be ads in between the free version and lessons but the number of lessons must be increased. Overall, a nice experience so far. I hope BRILLIANT looks into this matter and takes a BRILLIANT decision.

This app helped my mental health immensely in less than 2 weeks. You can learn or relearn about maths, physics, computers, software, even AI and quantum computers. The lessons are bite sized, but gradually get more complex. I haven't tried the free version since I had a free trial, but it's definitely worth it in my opinion, even if it didn't give anything extra, simply because of how much there is to learn. It's sort of gamified, which can help to stay consistent, and there's no pressure.
