# Excellence

> Excellence is a Y Combinator-backed (W25) AI education platform, founded by three Stanford-trained builders, that turns generative AI into a genuine learning tool rather than a homework-answer machine. Designed with teachers, it lets educators generate personalized assignments and exams, create interactive materials, and track student progress, while giving students an AI tutor that asks progressive questions instead of handing over answers. It began as an AI tutor for maths and science aimed at replacing costly private tutoring and long-term programs like Kumon.
