Brilliant
An interactive app for math, coding, science and data, built around hands-on problems and an AI tutor named Koji. Starts at advanced arithmetic and runs through algebra and beyond; Premium is $20 a month billed annually for one learner.
What is Brilliant?
Brilliant is an app and website for learning math, coding, science and data by solving problems. You don't watch long videos; you drag, tap and experiment, and each step gives instant feedback. Brilliant says its focus is math and coding, with 40 or more courses in all.
Its AI tutor, Koji, can see what's on screen, ask guiding questions and help when a learner gets stuck. Brilliant says Koji never just hands over the answer.
How it works
A learner picks a path, such as math or coding, and works through short concepts and practice sets. Each one takes a few minutes. Brilliant uses streaks, XP and leaderboards to build a daily habit. Premium members can jump to any topic, and free users go in order.
Kids can work on their own. Parents can follow progress on a dashboard or set up a Single Child plan to manage one child's account. Brilliant publishes lesson mappings to Common Core, SAT and ACT math to help families plan.
What it covers
| Area | Examples |
|---|---|
| Math | Fractions, proportional reasoning, algebra, functions, trigonometry, derivatives |
| Computer science | Thinking in code, Python, algorithms, neural networks |
| Science | Scientific thinking, circuits, quantum computing |
| Data | Visualizing data, probability, regression |
Brilliant says learners are ready once they can add, subtract, multiply and divide. Its about page says geometry, probability and calculus coverage is expanding in 2026.
Who it's best for
Brilliant suits motivated kids from about 10 through high school, and parents learning alongside them. It's a natural next step for strong elementary students leaving Beast Academy. Students who need a structured, graded course may prefer Art of Problem Solving classes or Math Academy. Younger kids still building basics will do better with Khan Academy.
Pricing at a glance
As of October 2026, Premium costs $20 a month billed annually ($240 a year) or $30 month to month. The Family plan covers 6 seats for $40 a month billed annually. The free tier allows 2 concepts a day. Brilliant says it holds one sale a year, around Black Friday.
Can a scholarship or ESA pay for it?
Brilliant has help pages on using ESA funds. It says it accepts payment through Arizona's ClassWallet and that Florida PEP and FES-UA families can request reimbursement as instructional materials. Those are Brilliant's own statements; each program decides what qualifies. Read more on our scholarships hub, Arizona's ESA and Florida scholarships.

Is Brilliant free?
There's a free tier. It gives 2 keys a day to unlock 2 concepts or practice sets, requires working in order, shows occasional ads and offers only a short preview of the Koji tutor. Premium removes those limits.
What age is Brilliant for?
Brilliant says most kids are ready around age 10, and curious 7- or 8-year-olds can do well if they're solid on the four operations. Its math starts at fractions and decimals and builds through algebra and beyond. Many users are teens and adults.
Is Brilliant accredited?
Brilliant says it is accredited by the Accrediting Commission for Schools, Western Association of Schools and Colleges (ACS WASC). It does not award course credits or degrees, so check with your umbrella school or district before counting it for credit.
Can Brilliant be used for homeschool?
Yes. Brilliant says many homeschool families use it as their core math and coding curriculum for the grades it covers. Its Common Core mappings help you plan, but you'll still want to track progress and assign work.
Is Brilliant worth it?
For a self-driven student who likes puzzles, usually yes, especially on the annual or family plan. If your child needs reminders and structure to study, try the free tier first.
Can I use ESA funds for Brilliant?
Brilliant says it works with Arizona ESA through ClassWallet and with Florida's PEP and FES-UA reimbursements. Rules change and each program decides, so confirm with your program and save Brilliant to your Edulist wishlist.
