Is Brilliant Worth It?
Honest assessment:
- Great for: Visual/interactive learners who want bite-sized STEM problems. The gamification genuinely makes math fun
- Not great for: Deep learning, exam prep, or professional development. Courses are broad, not deep
- The engagement problem: Most subscribers use Brilliant actively for 2-3 weeks, then usage drops off. If you haven't opened it in a month, cancel
Free Alternatives
- Khan Academy (free) — comprehensive math, science, CS courses. Less gamified but deeper content
- 3Blue1Brown (free, YouTube) — the best math visualizations on the internet. Covers linear algebra, calculus, neural networks
- Brilliant free tier — limited daily problems, but enough if you're casual
- Project Euler (free) — math + programming challenges. More advanced but excellent for problem-solving
- freeCodeCamp (free) — for CS and programming specifically
- MIT OpenCourseWare (free) — actual university-level STEM courses
⚠️ YouTube Sponsorship Bias: Brilliant sponsors nearly every STEM YouTube channel. If you signed up because a YouTuber recommended it, know that they're being paid to promote it. The product is decent, but the hype is marketing.
