Most AI in education is a chatbot that knows content. It answers questions. It explains concepts. That is useful — the same way a textbook is useful. But it is not teaching. Teaching requires knowing the specific student: what they understand, what they don't, how they think, where they get stuck, and what kind of explanation lands for them versus what bounces off.
The system I use builds that knowledge over time for every student, and uses it to drive every session that follows. The AI is not the teacher. It is the memory and the planner — the part that holds the student's full history and uses it to make every session smarter than the last.
