Brilliant vs MathScore

Brilliant is an interactive STEM learning service with courses in math, coding, data science, science, technology, and AI. Learners work through problems, explore visual models, and receive immediate feedback. Most courses include Koji, a digital tutor that guides learners through reasoning step by step. Free accounts can access all courses but are limited to two lessons per day in sequence, see occasional ads, and receive only a limited Koji preview. Premium adds unlimited lessons and practice, the option to jump to any lesson, an ad-free experience, and full Koji access. Individual Premium is listed at $20 a year, billed as one payment and renewed annually; Family Premium is $40 a year, also billed as one payment and renewed annually, with six seats included. Eligible K–12 teachers and their students may receive free Premium through an application-reviewed educator program. That program supports Google Classroom roster syncing and lesson sharing. Its reports show lesson completion, time spent, course progress, and completion dates, but not answer-level correctness or formal grades. Brilliant runs on Android, iOS, and web, and lessons require an internet connection and cannot be downloaded.

MathScore provides adaptive online math practice and assessment for learners from Kindergarten through Eighth Grade, Algebra 1, and Geometry. Practice is self-guided and develops through definition-level understanding, computational skill, and analytical understanding. The service aligns with Common Core and standards from some states that did not adopt it. Free topics are available at each K–8 grade level, and students can practice math facts for free without a stated time limit. A 30-day trial is listed, after which users can upgrade only the students ready for full topic access. The first paid student costs $9.95 a month, the second costs $3 a month, and each additional paid student costs $1.50 a month. Accounts never expire, and reports track student progress. Geometry includes a fill-in-the-blank proof engine. Signup supports parent or instructor accounts and single classrooms, with standards choices including Common Core, Minnesota, Ohio, Oklahoma, Texas, Virginia, Philippine, and None. Bulk discounts are available. The product was developed by MIT graduates starting in 2003, and the maker is based in Palo Alto, California.
