Khanmigo Went from 68,000 Users to 700,000 in One Year

When Khan Academy launched Khanmigo in March 2023, Sal Khan described it as an attempt to give every student in the world what wealthy families have always been able to buy: a personal tutor. The AI tutor, built on OpenAI's GPT-4, was initially tested with a small group of schools. Within a year, it had grown from 68,000 users to more than 700,000, with partnerships spanning over 380 school districts across the United States.

The growth is remarkable, but it is the pedagogical approach that makes Khanmigo distinct from other AI chatbots being used in education. Khanmigo is deliberately designed to not give students the answer.

The Socratic Method, Automated

The central design principle behind Khanmigo is the Socratic method: teaching through questions rather than answers. When a student asks Khanmigo to solve a math problem, the AI does not provide the solution. Instead, it asks the student what they have tried, where they got stuck, and what concepts they think are relevant. It guides them toward the answer through a series of progressively more targeted hints.

This approach is rooted in decades of education research showing that students learn more deeply when they actively construct understanding rather than passively receiving information. The challenge has always been scaling it. A great tutor who asks the right questions at the right moment is extraordinarily effective, but also extraordinarily expensive. At $40 to $80 per hour for a human tutor, personalized instruction is out of reach for most families.

Khanmigo costs $15 per student per year for school districts, and $44 per year for individual families. At that price point, it becomes feasible to offer every student in a classroom something approaching one-on-one tutoring support.

What Teachers See

Khanmigo is not just a student-facing tool. It includes a teacher dashboard that provides real-time insight into what students are working on, where they are struggling, and what misconceptions they hold. Teachers can see summaries of student-AI conversations, track progress across assignments, and identify students who need additional support.

The system also helps teachers with administrative tasks that consume a disproportionate amount of their time. Khanmigo can generate lesson plans aligned to specific standards, create differentiated assignments for students at different levels, and draft progress reports. In surveys conducted by Khan Academy, teachers reported saving an average of five hours per week on planning and administrative work.

Safety and Guardrails

One of the persistent concerns about AI in education is the risk of students using chatbots to cheat, or of AI systems producing inaccurate or inappropriate content. Khan Academy has invested heavily in guardrails to address both issues.

Khanmigo includes a moderation layer that monitors conversations for off-topic content, inappropriate language, and attempts to use the system to generate essays or complete assignments wholesale. The system is designed to redirect students who try to extract direct answers, consistently returning to the questioning approach. Teachers and parents can review conversation logs, providing an additional layer of accountability.

For accuracy, Khanmigo is anchored to Khan Academy's extensive library of vetted educational content. When helping with math, it draws on the platform's structured curriculum rather than generating explanations from scratch. This reduces the risk of hallucination, though Khan Academy acknowledges that no AI system is perfect and encourages students to verify important information.

The Equity Question

Khan Academy was founded on the principle that world-class education should be free. Khanmigo introduces a paid tier, which creates tension with that mission. The organization has addressed this by providing Khanmigo free to low-income school districts through philanthropic funding, and by keeping the core Khan Academy platform, with its thousands of videos and practice exercises, entirely free.

The $15 per student per year district pricing is significantly lower than competing AI education tools, some of which charge ten times as much. Khan Academy has received support from funders including the Gates Foundation, Google.org, and Bank of America to subsidize access for Title I schools and under-resourced districts.

What the Research Shows

Early efficacy studies are encouraging. A randomized controlled trial conducted in collaboration with Harvard and Stanford found that students using Khanmigo showed statistically significant improvements in math performance compared to a control group using standard Khan Academy tools without the AI tutor. The effect was most pronounced for students who started below grade level, exactly the population that benefits most from personalized instruction.

From 68,000 to 700,000 in a year. Over 380 district partners. A price point that makes AI tutoring feasible at scale. Khanmigo is not a replacement for great teachers, and Sal Khan is the first to say so. But it may be the closest thing to giving every student what the research says works best: someone who pays attention to them, meets them where they are, and asks the right question at the right time.
