SmartTutor vs. Khanmigo vs. IXL: Which AI Tutor Is Actually Right for Your Classroom?

They're Not Actually the Same Category of Product

This is the part most comparisons skip, and it matters more than any feature list: Khanmigo and SmartTutor are conversational AI tutors — IXL isn't.

• Khanmigo talks with students in real time, using Socratic questioning to guide them toward an answer rather than giving it outright.
• SmartTutor is also conversational — students work with Aria, an AI tutor, across 43 subjects, with real-time progress tracking for teachers.
• IXL is an adaptive practice platform. It has no real-time AI conversation at all — students answer questions, an algorithm (SmartScore) adjusts difficulty, and progress is tracked. It's excellent at what it does, but it's a different tool solving a different problem.

If what you actually need is a tutor a student can talk to and work through a problem with, IXL isn't really in that race — it was never built to be.

Pricing — The Real Numbers

Khanmigo

Free for K-12 teachers in the US. For families/individual students: $4/month or $44/year, covering up to 10 children on one account. Classroom-wide student access requires a formal district partnership — an individual teacher can't grant it independently. District enterprise pricing starts around $5–10 per student per year for the base platform, with Khanmigo itself layered on top at additional, not-fully-public cost — districts have to request a direct quote.

IXL

Individual/family plans start around $9.95/month for a single subject, scaling up for bundles. School and district pricing requires a custom quote; real-world examples put a ~200-student school paying roughly $4,000/year for math and ELA combined.

SmartTutor

Roughly $3 per student, per month for full access across all 43 subjects — with a free pilot available for schools and districts who want to test it with real students before committing budget. For context, IXL's real-world district example above (~200 students, ~$4,000/year) works out to roughly $1.67 per student per month — but for two subjects, not IXL's full library. SmartTutor's flat $3/student/month covers all 43 subjects at once, which is worth weighing against paying per-subject as a district's needs grow.

Access Model — A Real, Practical Difference

This is where the products diverge in ways that actually affect how fast a teacher can get started:

• Khanmigo requires a district-level contract before students can use it in class at all. A single motivated teacher can't just turn it on for their own classroom.
• IXL is a straightforward subscription — easier to start small, but the cost scales per student/subject as you expand.
• SmartTutor uses a teacher-approval model — a teacher can request classroom access directly, without needing a full district procurement process first, which matters a lot if you're trying to pilot something before asking your district for a budget line.

Subject Depth and Content Library

Be honest about this one: IXL's content library is genuinely enormous — over 8,500 individual skills across Math (Pre-K through Calculus), Language Arts, Science, Social Studies, and Spanish, built up since 2007. That depth is real and it's IXL's biggest strength.

Khanmigo's real strength is specifically math — reviewers consistently note it's the strongest AI tutor tested for algebra, geometry, and pre-calc, largely because it sits on top of Khan Academy's existing exercise library. Its coverage outside math (humanities, writing, world languages) is functional but noticeably shallower.

SmartTutor covers 43 subjects with a conversational AI tutor plus built-in engagement mechanics — live quiz games, badges, and a classroom leaderboard — that neither Khanmigo nor IXL currently offers in the same form.

The Honest Tradeoffs

Where Khanmigo wins

It's backed by Khan Academy's decades of free content and a large existing user base, has a well-documented safety/moderation system, and its math tutoring specifically is genuinely well-regarded by independent reviewers. If your priority is proven, large-scale math tutoring with strong district-support infrastructure, it's a real contender.

Where IXL wins

Raw content depth and breadth, particularly if what you actually need is structured skill practice and mastery tracking rather than conversational tutoring. Its SmartScore system is also a real point of friction worth knowing about — it penalizes wrong answers heavily near mastery level, and students frequently report frustration with it in reviews.

Where SmartTutor is different, not just newer

The teacher-approval access model, built-in classroom game mechanics, and free pilot availability are real, structural differences — not just smaller versions of what the other two do. What SmartTutor doesn't yet have is Khanmigo's or IXL's years of scale and independent track record — that's a fair, honest gap, and worth knowing going in.

Bottom Line

If you need proven, large-scale math tutoring backed by a major existing platform: Khanmigo. If you need deep, broad skill-practice content across every core subject: IXL. If you want a conversational AI tutor with classroom engagement tools built in, and you can start with a teacher-level pilot instead of a full district contract: SmartTutor is worth trying, especially while it's free to pilot.
