Aristotle vs MathScore

Aristotle is a web-based personal AI tutor for students from 6th through 12th grade. It offers voice lessons across subjects: the tutor speaks, listens live and can be interrupted. Rather than simply supplying answers, it asks questions to uncover gaps in understanding. An interactive whiteboard supports drawn steps, diagrams and images, and learners can upload PDFs and images, including long textbooks. The service advertises 65 subjects, including middle-school math, AP exams and SAT/ACT preparation. It tracks skills, mistakes and mastery, remembers prior sessions and preferred explanations, and gives parents a dashboard, lesson transcripts and session summaries. Its safety measures include guidance during lessons, a separate safety check, automatic post-session review and human review of flagged conversations. Aristotle says it does not keep raw voice recordings or sell family data. The free Intro plan provides three one-hour sessions. Scholar costs $49 a month for eight monthly sessions; Infinite costs $199 a month for unlimited sessions. Teachers and classrooms can access it free after verification.

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.
