What Synthesis Tutor is
Synthesis Tutor is a math learning product for children ages 5–11, available on the web and iOS. It covers standard K–5 material, from counting and arithmetic to fractions and algebraic thinking. Lessons tailor guidance to a child's knowledge and use real-time micro-assessments to check understanding; students move on after demonstrating mastery. Synthesis says AI is used where appropriate, while educators and neuroscientists guide much of the pedagogy and interactive experience. For children under 7, text and answer choices are read aloud automatically, and voice speed can be adjusted. The Tutor is offered in English and Spanish, with additional languages in progress. Families can choose monthly, annual, or lifetime options, with individual and family plans. Listed monthly plans include Individual Monthly at $35 a month for one child and Family Monthly at $29 a month for up to seven children. Annual and lifetime plans are also available. Synthesis also offers the product to classrooms, schools, homeschooling pods, and districts through an interest form.
