I've been using Brilliant to refresh my math skills after more than 20 years without using them since university, and I'm genuinely impressed. The platform makes learning fun, engaging, and challenging in exactly the right way. It keeps you thinking instead of just memorizing formulas, and I'm really enjoying the experience.
I recently ran into an issue where one specific lesson froze after the third question, both in the Android app and in my mobile browser. I contacted Brilliant Support, and they were incredibly friendly, attentive, and genuinely interested in helping.
They kept me updated, quickly identified the issue, and released a fix. I tried the lesson again, and everything worked perfectly—I was able to complete the level without any problems.
It's refreshing to see a company that not only responds quickly but also actually fixes the problem instead of sending generic replies. Great customer support, an excellent learning platform, and a team that clearly cares about its users. Highly recommended!

Thank you for such a thorough and kind review! We're glad the platform's hitting that sweet spot after 20 years away from math, and really appreciate you flagging the lesson freeze so our team could dig in and fix it properly. Happy learning!
They give you a short term free subscription and don't notify you when they will bill your credit card. Even if you find their system to be redundant and therefore unusable, and you terminate usage they don't alert you before they bill you. When you explain the problem to them, they tell you their policy is to not give refunds.
* Find somewhere better. They may claim to make you brilliant but they treat you like a moron. Definitely a rip-off.

A Game Changer for People Who Learn Differently
I’ve worked as a Creative Manager and UX Designer at Boston Dynamics for the past five years, and I absolutely love this app and its mission.
I’m currently teaching myself more of the technical side of my work so I can communicate more effectively with engineers and build things myself. Growing up, I struggled in school, moved around frequently, and had learning differences that often made traditional education difficult. This app has unlocked a side of technical learning that I never thought would feel so accessible. It has been a genuine game changer for me.
I’m currently working through a lot of computer science material, so I’m especially excited for more content featuring Koji. I also plan to introduce the app to my three children.
You have built what I believe is the best learning app on the market. More importantly, it can be an equalizer for students who learn differently, students like me and potentially my son, who has faced some of the same challenges.
Thank you for the work you do. It truly changes lives.

Thank you for sharing something this personal, it means a lot. We built Brilliant hoping it could be exactly that kind of equalizer, so hearing it's worked that way for you (and might for your son too) genuinely lands. Excited to have you working through the CS content, and we hope your kids find the same spark you did!
A truly human Customer Service. A breath of fresh air compared to traditional CS. The app is very user friendly and I actually felt I learned a lot. It is such a unique experience. I’m glad I found out about Brilliant.

Great experience for people who are paying
Great experience for people who are willing to pay but i feel like that’s not everyone and it only let me do two problems before making me get premium ,which you need to pay for.
I had trouble loading my course for a couple of days and lost my learning streak. Sam took care of the problem very quickly and I got back to work the next day.
I agree: give Sam a raise!

Cancelling Subscription
Honestly haven't really used it much sort of not my set up but definitely seems useful for those who need a more engaging way to learn. What I found most helpful is when I accidentally forgot to cancel my free trial which gave me quite a scare. I was able to reach out to them quite easily and get I refund despite when I searched it up people saying it was quite challenging to get one.

Although I was unable to use brilliant because of personal finance issues, the staff on brilliant were remarkably efficient and courteous regarding resolving my account issues.
They obviously take their customers seriously. I’m grateful for their quick atpainless resolution

Brilliant is out there doing more than their bit for humanity - making learning engaging and enjoyable is not always easy, but they manage it. On top of that their customer service is speedy, friendly and helpful. Can't recommend enough, thank you Brilliant (and specifically Sam, who helped me) xxx
The courses are great, though I haven't used them in a while. Hope to get back to it. The customer service is excellent too - they quickly cancelled my yearly subscription and reimbursed me when I explained that I simply had forgotten I was subscribed.

Application v good, refund given quickly
The application is very good, my son loved it.
The renewal came around and I did not have a reminder set, a full year's subscription was taken from my account, with an email after the fact to inform me. I do think a reminder should be automated by brilliant in advance to ensure good customer conduct use in place.
I did get a full refund however when I got in touch with brilliant, no questions asked. So i can't fault their response to my request. Thanks Sam!

App and The Customer service Super Good
The App is generally useful and really great. I wanted to cancel my subscription due to finishing my exams and I bought the subscription solely for my exams, so I contacted the customer service and they were super helpful. Thank you Brilliant!

Scam
Scam! They have commersial saying you can pay for / per month but you can only pay annually 2500 Swedish krona! Really dark patterns, avoid this company! Not tried the service but just bad services do it like this because they know that their service isn’t up to expectations!

After receiving an unexpected charge on my account, the customer service I received was some of the best I’ve ever had, to say the least. If I ever need any help in the future, I know exactly who to reach out to.
