First, we build AI teachers that read every step of a kid’s work, remember how that kid learns, and adapt to them every day. Our goal is an AI that teaches as well as the best human tutor.
Then we take the programs families already pay hundreds a month for (tutoring centers, writing schools, daily practice programs) and rebuild them around our AI teacher, so every family gets personalized education for a fraction of the price. It’s the same ritual families trust from Kumon or a writing school, with the AI teacher doing the teaching.
