Bravo to brilliant’s self-serving UX and bad customer support

Update: I received the refund. Thanks! I wish the process would be much easier. Modifying the rating from one to three.

I signed up for a monthly subscription since there is only a few courses I’m interested in. After I finished the course, I set a schedule to cancel the subscription before it renewed. I thought I canceled it because it asked me why I canceled and I selected my reason. I thought that’s it. To my surprise, they charged again. I went in and realized that the subscription is not cancelled because they hide the cancellation button at the very bottom of the page after you selected the reason so I didn’t successfully cancel it Lol. Well, I get it — you want to retain your user. But if a user does not want to use your product anymore, what’s the point of making the cancelation process so difficult. It felt like I was tricked. And customer support refused to refund due to internal policy even though I wasn’t using it at all - check your statistics please.

So for those of you who only find a few courses interesting, make sure when you cancel, scroll to the bottom of every single page. Otherwise, they will say it’s users fault.

Developer Response

Hi there – I'm very sorry about your experience with our support and cancellation flow. I've identified what I believe to be your account and initiated a refund of the latest payment via PayPal. We sincerely hope that the courses that you did on Brilliant were useful! 😃


Nice app, yet lean on learning

I subscribed to this service to refresh my memory on some fundamental concepts while also exposing myself to new areas of knowledge. Needless to say, this app is well-designed and flashy. The illustrations and user-interface are intuitive and engaging. However, this app lacks a lot with regards to pedagogy. While the brief lessons allow for quick consumption on-the-go, I think the superficiality of the explanations, examples, and exercises leads to shallow learning. If there were a practice/review tool that utilized a spaced-repetition learning model, I might feel more satisfied with my learning progress. In short, don’t expect the same learning outcomes from this app as you would from a more intensive course.



Don’t sign up for a year before you try the paid content!

I found that the content was VERY poor in some places, including outright errors in the paid content. For example, I was given an explanation to a puzzle where all dragons had red eyes (as opposed to blue eyes) and the solution said one of them has blue eyes. The solution was also worded so poorly I had to read it four times to understand what they meant even. For reference, I am an experienced attorney - logic problems and reading do not come hard for me.

I signed up for the yearly program with the expectation from the free content that what was in the paid content would be on par, but it was majorly inferior. Additionally, the mobile experience was poorly conceived and functioned intermittently. A complete disappointment.

I asked to cancel after a couple of hours into the monthly/1 year signup and they refused, asking me to find a way to enjoy the next 364 more days of this horrible app. F- for customer service. Shameful.

So try it if you like, but don’t sign up for more than a month until you get to see the app for the below-standard work that it is... or at least to know you like it.
