Tutor CoPilot Gives Human Tutors Real-Time AI Suggestions, with Larger Improvements Among Lower-Rated Tutors

In live K–12 mathematics tutoring, Tutor CoPilot suggests guiding questions, hints, and conceptual scaffolds to human tutors. A Stanford research summary reports that the randomized trial involved more than 700 tutors and more than 1,000 students.

The project team reports a four-percentage-point increase in the probability that students mastered a mathematics topic, rising to nine percentage points among students whose tutors had lower ratings.
