Apple / education / BRILLIANT: LEARN BY DOING
REVIEW
Brilliant turns STEM study into something you actually finish.
Interactive lessons in math, computer science, and AI replace passive video with hands-on problem solving — and it shows in the completion rates.

Most learning apps are video players with a streak counter bolted on. Brilliant isn’t. Open a unit on neural networks and the second screen is a draggable weight matrix; open one on probability and you’re sliding the parameters of a distribution to match a histogram. The app’s central conceit — that you learn STEM by doing it, not by watching someone else do it — is the rare edtech promise the product actually keeps.
That alone explains why Brilliant has held its corner of the category while bigger players consolidated. Khan Academy stayed free and stayed video-first. Coursera pivoted to professional certificates and university-branded specializations. Duolingo cornered languages. Brilliant kept building one interactive math, CS, and AI lesson at a time, and a decade in, those lessons are why the daily set still gets done.
The question isn’t whether Brilliant teaches well — it does. The question is whether $150 a year is the right price for what amounts to a very good study app with no credential at the end.
Brilliant's pitch is that you learn by doing, and the app holds that line where Khan Academy and Coursera quietly drift back to lecture videos.
FEATURES
Brilliant is built around short interactive lessons rather than lecture videos. Each topic — Algebra 1, Logic, Neural Networks, Probability, Computer Science Fundamentals — is broken into 15-minute units that drop you straight into a problem with a manipulable diagram, a draggable graph, or a guided proof. You tap, drag, and answer. You don't watch.
The catalogue spans foundational math through calculus, statistics, computer science, data analysis, and a steadily growing AI track covering everything from neural networks to large language models. There are roughly 70 courses on the iOS app today, with new units shipped on a rolling schedule.
Daily Challenges anchor the home tab — a small, hand-picked problem set you can clear in five minutes. Streaks, badges, and a leaderboard handle the gamification layer. Lessons download for offline use, which matters more than the marketing suggests when you actually study on a commute.
MISSION ACCOMPLISHED
The pedagogy is the thing. Brilliant's pitch — that you learn STEM by doing it, not by watching someone else do it — is the rare edtech promise the product actually keeps. The interactive widgets are well-built; the problem sequencing assumes you've forgotten the previous step and rebuilds it cleanly.
The AI track is the most current part of the catalogue. Courses on how transformers work, how diffusion models generate images, and how to reason about LLM behaviour landed faster here than at any university extension program. For someone trying to understand the machine learning their job suddenly requires, that's the use case.
ROOM TO IMPROVE
Brilliant Premium is $24.99 a month or $149.99 a year (with the annual price often discounted to around $120 in-app). That's competitive with Coursera Plus but materially more than Khan Academy, which remains free. The free tier on Brilliant is narrow — a small slice of each course and the Daily Challenge — so you'll hit the paywall fast.
Depth is the other honest caveat. Brilliant gets you to working intuition on a topic; it does not get you to a graduate-level treatment. There are no problem sets graded by an instructor, no certificates a hiring manager has heard of, and no calculus track that goes past multivariable. For exam prep or a credential, look elsewhere.
CONCLUSION
Install Brilliant if you've bounced off Khan Academy because the videos felt slow, or off Coursera because the assignments felt like homework. Pay for it if you'll do the daily set five times a week — and cancel without guilt if you won't, because the model only works when you show up.
