What families should know

Brilliant is a subscription learning platform built around short, interactive daily lessons rather than video lectures — you solve your way through each concept. Courses span math (from foundations through calculus), science, computer science, data analysis and AI, and the platform aims at roughly ages 10 and up, which in practice means motivated middle- and high-schoolers (and plenty of parents). There is a free tier with limited access and a 7-day trial on the annual plan; the annual plan costs less per month than monthly, and an Annual Family Plan covers up to 6 members with separate accounts for each. Worth knowing: it is self-paced with no teacher, no feedback and no certificates — so it works best for a kid who is genuinely curious and will keep a daily habit, and less well as a substitute for a tutor if your child is struggling in school. K–12 teachers and their students may qualify for free Premium through Brilliant for Educators.

Frequently asked questions

What age is Brilliant.org good for?

Brilliant aims at roughly ages 10 and up. In practice it suits motivated middle- and high-schoolers who like puzzles and problem-solving; younger children generally need an adult alongside them. There is no separate kids version — the same courses serve teens and adults, starting from foundational levels.

Does Brilliant.org cost money, and is there a free option?

There is a free tier with limited access to lessons, plus a 7-day free trial on the annual plan. Premium is sold monthly, annually (cheaper per month) or as an Annual Family Plan covering up to 6 members, each with their own account. K–12 teachers and their students may qualify for free Premium through the Brilliant for Educators program — check educator.brilliant.org.

Is Brilliant.org a good replacement for a math tutor?

Usually not. Brilliant is self-paced with no instructor, no personalised feedback and no certificates, so it rewards a curious kid who will build a daily habit. If your child is behind in school or needs accountability, a tutor or small-group class works better — see our tutors directory. Many families use both: a tutor for school material, Brilliant for enrichment.

What subjects does Brilliant.org cover?

Math from foundations through calculus, plus science, computer science, programming, data analysis and AI. Lessons are short and interactive — you work through problems instead of watching videos — and the platform builds a suggested path from the interests you select.
