Our verdict
Brilliant turns concepts into clever interactive puzzles and makes daily practice genuinely fun; it is the nicer product to use. Khan Academy covers more ground, goes deeper on fundamentals with its mastery system, and costs nothing, ever, from a nonprofit without ads. As a paid habit Brilliant is defensible, but on value and completeness the free champion wins: Khan Academy first, Brilliant as the fun upgrade.
“Completely free, no catch, no upsell: a nonprofit that teaches math, science, and economics better than most paid platforms. The gold standard for foundational knowledge.”Editorial team, on Khan Academy
“Learning math and computer science by solving puzzles instead of watching videos works absurdly well. Fifteen minutes a day actually sticks. Depth is capped, motivation is not.”Editorial team, on Brilliant
