Is Brilliant Worth $150/Year?

Brilliant's interactive approach is genuinely unique — you learn by doing, not watching videos. The value depends on how you use it:

Keep it if: You do 15+ minutes daily and are actively progressing through courses. The interactive format teaches deeper understanding than videos.
Cancel if: You open it once a week, only do daily challenges, or have been on the same course for months. At that usage level, free YouTube content is better value.

🎯 Bottom Line

Cancel at brilliant.org/account or through your app store. Annual plans refundable within 30 days. The free tier is very limited (1 problem/day). For free alternatives, Khan Academy + 3Blue1Brown covers most of what Brilliant teaches. Your progress is saved if you return.
