An AI tutor is not the same as an AI chatbot. A chatbot answers your question. A tutor refuses to, and instead asks you a question back. The point of a tutor is to make you smarter, not to make your assignment shorter.
Three tools dominate the AI tutor category for students in 2026: Khanmigo from Khan Academy, Socratic by Google, and ChatGPT (especially in Study Mode). They overlap in some ways and differ in important ones.
Here is the head-to-head, including which one is right for which kind of student.
Khanmigo: The Curriculum-Anchored Tutor
Khanmigo is Khan Academy's own AI tutor, built on top of Khan Academy's curriculum and grounded in its content. It does Socratic questioning by design: it never simply gives an answer, it always asks a guiding question, and it points you back to the relevant Khan Academy lesson when you are stuck.
Strengths. Pedagogically careful in a way that ChatGPT and Socratic are not. Will not just hand you the answer even if you push. Strong for K-12 math and science. Tied tightly to Khan Academy's curriculum, which means consistency between the lesson, the practice problems, and the tutor.
Weaknesses. Bounded by Khan Academy. It cannot help with your teacher's specific test prep, your professor's syllabus, or material that Khan Academy does not cover. Writing and humanities tutoring are noticeably weaker than math and science. The Socratic insistence can feel slow when you genuinely just want the answer to move on.
Pricing. $4 per month or $44 per year for individuals. Free for many school and district partnerships.
Socratic by Google: The Quick Homework Lookup Tutor
Socratic is Google's free AI homework helper. It is built around photo-based question lookup: take a picture of a homework problem and Socratic shows step-by-step explanations, related video lessons, and links to relevant content.
Strengths. Free. Easy to use. Covers every subject. Strong for younger students and parents who want a single tool that does not require extensive coaching to operate.
Weaknesses. Less interactive than Khanmigo or ChatGPT. It is closer to a smart search engine than a tutor. The explanations are pulled from existing web content, which means quality varies by subject. It does not adapt to your level the way a real tutor would.
Pricing. Completely free.
ChatGPT (with Study Mode): The Broad, Configurable Tutor
ChatGPT in Study Mode is now the most flexible of the three. It does Socratic questioning when Study Mode is on, but it is unbounded by curriculum and can use any course material you upload as the basis for instruction.
Strengths. Works across every subject, every level. Accepts your own PDFs, slide decks, and notes as context. Strong on writing and humanities, which Khanmigo struggles with. Memory across sessions makes it feel like a tutor that actually knows you. Available on every plan, including free.
Weaknesses. Less pedagogically careful than Khanmigo. If you push hard for an answer, it will eventually give one. The quality of the tutoring depends a lot on how well you prompt it. Younger students may need help getting set up.
Pricing. Free tier covers most students. ChatGPT Plus at $20 per month adds higher usage limits and faster models.
Subject-by-Subject Winner
- K-12 math, foundational science. Khanmigo. The combination of pedagogical discipline and curriculum anchoring is genuinely the best teaching experience for this segment.
- College math, calculus, statistics. ChatGPT Study Mode. Khanmigo's coverage thins out at the upper end of math.
- Writing and English. ChatGPT (or Claude, if you have it). Khanmigo's writing tutoring is workable but not its strength.
- History and humanities. ChatGPT. Strong for essay structure, primary source analysis, and concept connections.
- Standardized test prep (SAT, ACT, AP). ChatGPT with uploaded prep books. Khanmigo has some SAT support; ChatGPT has more flexibility.
- Quick homework lookup, younger kids. Socratic. Easier UI, less coaching required.
- Tutoring in your school's specific material. ChatGPT, because it can ingest your specific notes, slides, and syllabus.
Which One Refuses to Just Give the Answer?
This matters more than students initially think. The whole point of a tutor is that it is willing to slow you down, and the three tools differ sharply on this.
Khanmigo: Strict. Will not give you the answer even if you ask repeatedly. This is the explicit design.
ChatGPT in Study Mode: Moderately strict. Will Socratic-question by default. Will give in if you escalate to "just tell me the answer."
ChatGPT in normal mode: Will give the answer immediately.
Socratic: Will show you the answer (it is a search-style tool, not a tutor in the strict sense).
If your goal is to learn rather than to finish, Khanmigo and ChatGPT-in-Study-Mode are the only two that actually enforce the tutor pattern.
Which One Has the Best Memory?
Real tutoring builds on what you covered last week. Memory matters.
ChatGPT has explicit cross-session memory (when enabled). It can remember your class schedule, your weak areas, and how you like explanations delivered. This is the strongest memory of the three for tutoring purposes.
Khanmigo has memory inside Khan Academy. It knows what lessons you have done and which concepts you have struggled with, but the memory is scoped to the curriculum, not to you as a learner with messy real-world coursework.
Socratic has effectively no memory. Each query is independent.
Which One Should Each Type of Student Use?
Middle school students
Start with Khanmigo if you can afford the $4 a month, or Socratic if you cannot. Khanmigo's curriculum scaffolding is the right level of structure for this age group. Save ChatGPT for high school.
High school students
Khanmigo for math and science homework where understanding matters. ChatGPT with Study Mode for everything else. Socratic as a backup for quick lookups on the bus.
College students
ChatGPT with Study Mode as the daily driver. Upload your own course material; that is where the tool earns its keep. Khanmigo only if you are reviewing foundational math.
Graduate and professional students
ChatGPT plus Claude. Khanmigo is not built for this level and Socratic is not relevant. Use Claude for writing-heavy work and ChatGPT for everything else.
Test-prep students (SAT, ACT, AP, NCLEX)
ChatGPT with uploaded prep materials, plus a dedicated test-prep platform (UWorld for NCLEX, College Board's Bluebook for SAT, etc.). Khanmigo for SAT specifically has improved a lot, and is worth trying first if SAT is your only test.
The Honest Recommendation
If you want one tutor for one student, ChatGPT with Study Mode is the right pick in 2026. It is free, it covers every subject, it works with your own material, and Study Mode enforces enough of the tutor discipline that you actually learn.
Khanmigo is the better choice for K-12 students whose parents want a tightly-scoped, pedagogically safe option. The $4 a month is among the best deals in education software.
Socratic remains a useful free backup, but it is more search than tutor and should not be your primary learning tool.
Key takeaways
- Khanmigo costs $4/mo and refuses to give the answer outright — the strictest tutor of the three.
- ChatGPT Study Mode is the best free, broad option for college students and writing-heavy work.
- Khanmigo wins for foundational K-12 math and science. ChatGPT wins for everything else, including college work and humanities.
- ChatGPT has the strongest cross-session memory; Khanmigo's memory is scoped to Khan Academy's curriculum; Socratic has none.
- If you only pick one tutor in 2026, pick ChatGPT with Study Mode. It is free and works across every subject.

FAQ
Is Khanmigo better than ChatGPT for students?
For K-12 math and science tied to Khan Academy's curriculum, yes. Khanmigo is more pedagogically careful, never gives answers outright, and is anchored in Khan Academy's content. For everything else (writing, college work, custom material), ChatGPT with Study Mode is now broader and equally Socratic when you turn the feature on.
Is Socratic by Google still good in 2026?
Yes, especially for younger students and homework photo lookups. It is free, simple, and covers every subject. It is less powerful than Khanmigo or ChatGPT but easier for middle schoolers and high schoolers to use without coaching.
How much does Khanmigo cost?
Khanmigo for individuals (parents and students) is $4 per month or $44 per year. Khan Academy Districts and many school partnerships make it free for participating schools.
Can these tools help with homework that isn't in their curriculum?
ChatGPT can. Khanmigo is bounded by Khan Academy's content, which is broad but not infinite. Socratic searches broadly across the web, so it can find help on most subjects.
