About Synthesis

Synthesis is an AI-powered maths and problem-solving platform originally developed for students at SpaceX's school programme and now available publicly. The platform takes a games-based approach to mathematical thinking: rather than drill-and-practice exercises, Synthesis presents students with adaptive puzzles, strategy challenges, and collaborative problem-solving scenarios that build numerical reasoning, logical thinking, and mathematical intuition. The AI adapts in real time to student performance, adjusting difficulty and presenting new challenge types based on individual progress. Synthesis covers arithmetic through pre-algebra, with particular depth in areas where students typically struggle: fractions, percentages, estimation, and multi-step word problems. Parent and teacher dashboards show session data, skill progression, and engagement metrics. Synthesis is positioned as a supplement to school maths rather than a replacement, with 3-4 sessions per week delivering noticeable gains in mathematical confidence. The platform has strong efficacy data and significant word-of-mouth adoption among parents and homeschooling families. It is one of the more pedagogically differentiated AI maths tools available for ages 6-14.

Compared with Synthesis (1)

  • Synthesis vs Khanmigo โ†’tie

    Khanmigo vs Synthesis is the Socratic AI tutor built on Khan Academy's curriculum library against the games-based adaptive maths platform developed from SpaceX's school programme. Both are designed to improve student learning outcomes, but they work through fundamentally different approaches and serve different educational contexts. Khanmigo is a text-based tutoring assistant that guides students through subjects using the Socratic method - asking questions rather than providing answers - across a broad curriculum including maths, science, history, and writing. It also functions as a teacher planning tool, generating lesson plans, rubrics, and discussion prompts. Its breadth, curriculum alignment, and SAT preparation partnership with College Board make it a strong fit for K-12 classroom settings and home study across multiple subjects. Synthesis takes a narrower, deeper approach to maths. The platform is built around adaptive strategy games and collaborative problem-solving scenarios that develop mathematical reasoning and intuition rather than just arithmetic fluency. The AI adjusts in real time to each student's performance and challenge tolerance, building confidence alongside skills. Independent efficacy data supports meaningful learning gains. The choice is primarily about scope: families and teachers who need broad curriculum support across subjects should look at Khanmigo. Families whose primary goal is building mathematical confidence and problem-solving ability in children aged 6-14 will find Synthesis more focused and more effective for that specific outcome.
