#1AI tutoring platforms have crossed a critical threshold: peer-reviewed studies of Carnegie Learning MATHia show effect sizes of 0.30–0.45 versus control, which meets or exceeds the average effect size of live classroom instruction (Hattie meta-analysis benchmark ~0.40). Khan Academy's Khanmigo, deployed across millions of students, offers on-demand Socratic tutoring at zero marginal cost per session. Synthesis, now consumer-facing, reports engagement and problem-solving gains that have attracted significant attention from homeschooling and microschool markets — demonstrating parent willingness to substitute AI for classroom instruction.
