Khanmigo

The tutor is anchored to Khan Academy content, which is also where its limits lie — it works best tethered to Khan exercises. Math is its strongest subject, with science, humanities, and AP/SAT support also strong. Writing is the weaker area, though it has improved since the early 2024 release.

Khanmigo is free for US K-12 teachers via district sign-up and paid for parents and learners. The pricing is $4 per month or $44 per year per parent account, covering up to 10 children under 18. This is exceptionally cheap relative to other AI tutors and effectively sets the price ceiling for the category. Khan Academy itself remains free — Khanmigo is the only paid product in the Khan ecosystem.

Format is web-based at khanmigo.ai with mobile app integration through Khan Academy's iOS and Android apps. There is no affiliate program — Khan Academy is a nonprofit.

Homeschool reviews trend strongly positive. One widely-quoted homeschool parent: 'completely revolutionized our homeschool — perfect for kids who ask why constantly.' A study by myengineeringbuddy reported 23% improvement in concept retention in an 8-week, 12-student study. Late-2023 Reddit teacher critiques noted that early Khanmigo 'fell short' on geometry and had limited role-play characters — both have improved significantly since.

At $44 per year for up to 10 children, Khanmigo is the cheapest credible AI tutor on the market. It works best for families already using Khan Academy as their math or SAT spine, curious 'why' kids who need a dialogue partner, multi-child families (10 children per account is unmatched), budget-conscious families, and AP/SAT prep. It is not the right fit for families not using Khan Academy core content, writing-heavy or humanities-heavy households, or screen-averse families.
