If Koji were a human tutor and they taught my kid Geometry/Algebra II the way shown in these two demos, I’d fire them immediately. Ignore the shiny marketing and focus on what’s actually happening in these demos. - Koji allows the student to fumble around without a clue for a while. - Koji, then realizing the kids are confused, introduces some test points (a finite selection of what could be infinitely many), without explaining why any of these are good candidates: they just appear. - Students then proceed to test to see which point satisfies the equation - a Prealgebra standard. - But here’s the kicker - the most important concept the student needs to grasp, the reasons why the center of the circle is located at (1,0), is completely missed! Instead, the student just lines the circle up with the test point. But according to Koji, “you got it!” No, you have not. No high-quality human math tutor would ever do this. The second example (plotting the transformed square root) is even worse. Students cannot think with knowledge they do not have! I genuinely don’t like criticizing others who are trying to improve education. But since this has gone super-viral with almost nobody pushing back on these blatant issues, I felt I had no choice.

TutorMoments: Do AI tutors know when to help and when to hold back?
Ai2 introduces TutorMoments, a replay-based evaluation framework and dataset for measuring whether LLMs can balance when to help and when to hold back in one-on-one math tutoring. Preliminary results show models tend to over-help, and prompt engineering only partially closes the gap to human tutors.
Retrieval-Augmented Tutoring for Algorithm Tracing and Problem-Solving in AI Education
This paper presents KITE, a Retrieval-Augmented Generation (RAG)-based intelligent tutoring system for algorithmic reasoning and problem-solving in AI education. The system uses intent-aware Socratic response strategies and multimodal RAG to provide course-grounded, pedagogically appropriate feedback, and is evaluated through metrics, expert review, and simulated student interactions.
