Khan Academy's LLM tutor that guides students with questions rather than answers, scaled to 700,000+ students across 380+ US districts — though a Stanford study found access alone doesn't improve outcomes.
Khanmigo is Khan Academy's LLM-based tutor that coaches students through guided questioning rather than giving direct answers, and provides teachers with lesson plans, rubrics and grouping tools; usage grew from approximately 68,000 users in 2023–24 to over 700,000 students across 380+ US district partners in 2024–25, including a 170,000-student state rollout in Arizona.
A Stanford study found that merely offering the tool did not create meaningful engagement or improve reading outcomes — only about 53–61% of students used it even when given time.
Implementation detail (cost, timeline, staffing, conditions for success) is not yet available for this practice.
