Astra AI vs Khanmigo: which tutor fits how you study?
Choose Khanmigo if you study inside Khan Academy's content library, want an assistant that deliberately withholds direct answers, and meet its US purchaser requirements. Choose Astra AI if your course material lives in your own notes, slides and past papers and you want one workflow that connects tutoring to an exam plan. Astra AI is our product, so this comparison gives Khanmigo the advantage wherever it is the better fit.

Quick verdict

How do their teaching styles differ?
Khanmigo's core promise is that it does not hand over the answer. Khan Academy describes it as prompting learners to think, solve and discover the next step. Its strongest context is an exercise, video or article inside Khan Academy, where it can help with the exact material already on screen.
Astra also puts the answer last and asks questions back, but the starting context can be any question or any material you upload. The product is designed to keep moving from explanation to practice: ask a question, get a worked walkthrough, then generate similar questions, flashcards or a mock exam.
Neither approach guarantees learning. If a student keeps pressing for the final answer, both products can become an answer machine. The useful test is whether you can solve a new question alone after the session.
Which one works better with your own course material?
Astra is built for course material. You can bring notes, lecture slides, PDFs, past papers and photographs of questions. That material can become the basis of a study plan, flashcards, quizzes and lessons. It is the better fit when the exam is specific to what your teacher taught, rather than to a public curriculum.
Khanmigo's advantage is a carefully sequenced public library. You do not need to prepare material before getting help, and the exercise context comes from one of the most established education nonprofits. If your syllabus aligns with Khan Academy, that structure can be more valuable than upload flexibility.
Which is better for exam preparation?
Astra has a clearer dedicated exam workflow. Exam Prep uses the exam date to order topics, creates practice and includes graded mock exams. The page also shows progress, so revision can adapt when a topic is still weak.
Khanmigo is useful for understanding and practising individual concepts, and it has test-preparation support. The planning burden remains with the student: decide what to review, in what order, and how to turn coverage into a realistic timetable.
If you already know exactly what to study and only need help at the moment you get stuck, Khanmigo can be enough. If you need the plan itself, Astra is the more direct choice.
How do price and eligibility compare?
Khan Academy lists Khanmigo for learners and parents at $4 per month or $44 per year, excluding sales tax. The public learner page says the purchaser must be at least 18, live in the United States and have a US billing address. A parent account can add up to 10 children.
Astra's public pricing starts at $9.99 per month, with annual plans advertised at roughly 17% less than monthly billing. The product includes every subject and the full study toolkit rather than selling separate subject tutors. Check the Astra pricing page for the current tiers.
On headline price, Khanmigo wins. On value, the answer depends on whether Astra's uploads, exam planning and integrated practice replace other tools you would otherwise buy.
What are the honest limitations?
- Khanmigo's learner access is not available globally and classroom use depends on school or district access.
- Astra does not provide a human tutor, and its full workflow is paid rather than free.
- Both are AI systems that can make mistakes, especially on diagrams, multi-step calculations and nuanced written work.
- No tool can guarantee a grade. The quality of your material, practice and checking still matters.
Choose Khanmigo if...
- You study inside Khan Academy and want help on its exercises and videos.
- You are in the United States and $4 a month fits your budget.
- You want an education-specific assistant without preparing your own material first.
- You mainly need concept-level guidance rather than a complete exam plan.
Choose Astra AI if...
- Your exam is based on class notes, slides or past papers.
- You want tutoring, flashcards, quizzes and mock exams connected in one place.
- You need a plan built backwards from an exam date.
- You are looking for one subscription across school or university subjects.

How can you test both tutors in two weeks?
Pick one topic that will appear on your next test and use the same source material with both products. For the first week, work only inside Khan Academy's matching exercises and videos with Khanmigo. For the second week, upload the class notes or past paper to Astra, work through the tutor and finish with a generated quiz or mock question.
Do not judge the products by how impressive the first explanation feels. Finish each week with a different question that you solve alone, then explain the method out loud without looking at either chat. Record three things: whether you needed the source material, how quickly you found the right topic and whether the practice matched the wording of your exam.
- Use the same amount of study time for each product.
- Start with a hint and ask for the full solution only after a real attempt.
- Finish with one fresh question with no AI assistance.
- Keep the product whose workflow you would still open on a busy school night.
This is also a fair way to account for price. A cheaper product that leaves you searching for another planner, card maker or practice test may no longer be cheaper. Equally, a broader product is not good value if you only use ten minutes of card review.
Frequently asked questions
Astra is better for preparing from your own notes and past papers toward a specific exam date. Khanmigo is better if you already study inside Khan Academy, need a lower-priced learner plan and meet its US eligibility requirements.
Khan Academy says Khanmigo guides learners to find the answer instead of simply giving it. The exact experience depends on the task, but its stated design is learning-first.
Astra covers school and university subjects across maths, sciences, humanities, computer science and languages in one subscription. Quality can still vary by topic and problem type.
Khanmigo lists $4 per month or $44 per year for learners and parents. Astra starts at $9.99 per month. Compare total cost after accounting for other flashcard, quiz or exam-prep tools you would otherwise pay for.
That depends on your school, teacher and course rules. Use the tool to understand the method, follow any AI-use policy, and do not submit generated work as your own when that is prohibited.
