About Synthesis

"AI-powered math and reasoning tutor that makes learning feel like a game"

Synthesis started as an enrichment program for students at SpaceX's Ad Astra school, designed to build the problem-solving and mathematical reasoning skills needed for the 21st century. After opening to the public, it has become one of the most innovative AI education platforms for children. Synthesis takes a fundamentally different approach to math education. Instead of drilling arithmetic procedures, it develops mathematical thinking through collaborative problem-solving games and puzzles that require strategic reasoning, experimentation, and iteration. Students are motivated by challenge and discovery rather than correctness metrics. The AI adapts in real time to each student's performance — increasing challenge when mastery is demonstrated, providing scaffolding when students struggle, and identifying specific conceptual gaps to address. The curriculum covers number sense, algebra, geometry, logic, and statistics, but always through applied thinking rather than rote practice. Synthesis Tutor, the AI-powered direct tutoring product, provides personalized one-on-one instruction for students who need targeted help. It explains concepts, works through problems step-by-step, and adapts its teaching approach based on the student's comprehension signals. Children who have used Synthesis consistently show significantly accelerated math progression compared to traditional instruction. It is used by parents seeking enrichment beyond school, homeschool families, and schools as a supplemental program.
