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.

The app could get five stars, the thing that gets in the way it's the absurdly small amount of keys you can get per day. 2 everyday if you're a free to play user. This makes the app get tiring to use: You use all your keys in >10min, making you unable to learn much and wait long to be able to learn again. I feel like the app could have alternative ways to claim keys (like watching adds or completing certain tasks)

Thanks for sharing your experience. We hear you on the daily key limit, and free access is built for steady, daily learning while Premium removes those limits for longer, uninterrupted sessions. We'll pass your idea about alternative ways to earn keys along to our team.

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 would have given a full mark if there had been multiple premium bundles, as I understand that premium subscribers should have privileges that free members can't access. However, I can't afford the yearly subscription all at once, and so many installers. Edit: Didn't expect a fast beneficial reply, but here we are! Such a hardworking team

We appreciate the feedback—flexible pricing is important. We know yearly plans aren’t always feasible, and we’ll share your suggestion for more premium bundle options with the team.
