9 Best AI Tutors of 2026

By the HearSmart research desk · Updated November 12, 2026 · Next review December 27, 2026 · 9 products compared

Ranked firstChatGPT (study mode)high school, college and adult learners in any subject9.0

The short version

Khanmigo is the best AI tutor for most students: $4 per month buys a tutor that asks questions instead of giving answers, tied to Khan Academy's full course library, with a parent account for families. ChatGPT's study mode is the strongest free option and the best for college and adult learners, since it works from your own notes, slides and PDFs. Gemini is close behind with a free plan and a $4.99 upgrade. For math alone, Photomath is the quickest free step-by-step solver and Mathos AI adds video explanations. Synthesis Tutor is the pick for young children, Brainly for parents who want a human advisor, Tutor AI for building a course on any topic, and Chegg Study for college textbook solutions.

Short answer

Khanmigo is the best AI tutor for students in 2026: it costs $4 per month and guides learners through every Khan Academy exercise without handing over the answer. ChatGPT suits college students and self-learners because study mode is included on its free plan, and Photomath and Gemini also have free plans. Families with kids ages 5 to 11 should pick Synthesis Tutor, whose $119 yearly plan covers up to 7 children; prices as of November 2026.

This list is for students and self-learners who want an AI tutor for homework help and study practice, and for parents choosing one for a child. We compared documented features and published US prices for 9 AI tutors sold today: general assistants with study features, curriculum-based tutors, math solvers and course builders. Scores weigh performance at 40%, ease of use at 25% and value at 35%, where performance covers how well the tool teaches rather than just answers, subject range, use of your own course materials and parent controls. Facts and prices come from each vendor's own website as shown on November 12, 2026. Brainly and Chegg Study did not show a US price we could check, so those prices are marked as pending. We left out Socratic by Google, whose site now redirects to Google Lens, and Quizlet and Gauth, whose sites blocked our checks.

    Price

    Free plan includes study mode; ChatGPT Plus is $20 per month, and a lower-cost Go plan is also sold

    Quoted from the ChatGPT (study mode) pricing page on November 12, 2026: ChatGPT Plus is a subscription plan that provides enhanced access to the ChatGPT web app for $20/month.

    ChatGPT's study mode turns a general chatbot into a patient tutor for any subject. OpenAI's help center says study mode is available across ChatGPT plans globally on web, iOS and Android, so a student can use it without paying. Instead of only producing a final answer, it asks what you already know, explains in layers, and checks your understanding with open questions. Its biggest advantage over subject-specific apps is range: you can upload a syllabus, lecture slides, a PDF chapter or a photo of a chemistry problem, and it works from that material. It can also quiz you one question at a time before a test. The weaknesses follow from its breadth. There is no built-in course or progress map, so the learner has to say what level and topic they are on, and study mode is not available in Projects or Temporary Chats. ChatGPT Plus at $20 per month raises usage limits, but most students can start on the free plan.

    What it does well

    • +Study mode is on the free plan
    • +Covers any subject and level, from middle school to college
    • +Turn it on by typing @study or visiting chatgpt.com/studymode

    Where it falls short

    Khanmigo

    Price

    $4 per month or $44 per year for learners and families; free for teachers

    Quoted from the Khanmigo pricing page on November 12, 2026: For you $4/month $44/year

    Khanmigo leads this list because it pairs a tutor that refuses to hand out answers with one of the largest free course libraries for school subjects. Khan Academy says you can get personalized tutoring on every exercise, video and article on its site, so a student stuck on a practice problem gets questions and hints right where the problem sits. The same subscription covers a writing coach that gives feedback and runs debates, plus code review for JavaScript, HTML, Python and SQL. You can talk to it instead of typing, and it reads its replies aloud. The family plan costs the same $4 per month and adds a parent account with chat history and moderation alerts. The limits are clear: there is no free tier for learners, and the tutor stays inside Khan Academy's material, so it is less useful for a college course or an unusual assignment. Students who want instant final answers should look at Photomath or Chegg Study instead.

    What it does well

    • +$4 per month is the lowest paid price on this list
    • +Tied to a full free course library from math to coding
    • +Parents can review a child's conversations

    Where it falls short

    • −No permanent free plan for learners
    • −Help is limited to Khan Academy's content and topics
    • −Students who only want a quick answer will find it slow by design

    Quoted from the Google Gemini pricing page on November 12, 2026: Get more access to new and powerful features to boost your productivity and creativity. $4.99 / month

    Gemini is Google's general AI assistant, and its US plans page pitches it directly at students. You can upload an image or file of homework and Gemini breaks it down with step-by-step guidance aimed at showing how to reach the answer, and you can turn notes or slides into a study guide or a practice test before an exam. The free plan, which only needs a Google Account, already includes Deep Research, Gemini Live and Canvas, although it runs on the Flash-Lite model. Google AI Plus costs $4.99 per month and doubles the usage limits, while Google AI Pro at $19.99 per month adds the Pro model and four times the free limits. Google says limits refresh every 5 hours until you hit a weekly cap, which matters during exam weeks. There is no curriculum and no parent dashboard, so Gemini suits older students and self-learners more than young children.

    What it does well

    • +Free with any Google Account

    Quoted from the Photomath pricing page on November 12, 2026: Billed Monthly $9.99 USD

    Photomath is the fastest way to see how a math problem is solved. You point your phone's camera at a problem, including word problems, or type it into the smart calculator, and a solution appears, sometimes with more than one method to choose from. Its site lists coverage from elementary math to algebra, geometry, trigonometry, statistics and calculus. The free Basic plan already includes step-by-step explanations, which is more than many paid apps offer. Paid plans cost $9.99 billed monthly or $69.99 billed annually and add custom visual aids and extra tips on how and why each step works. The catch is that Photomath leads with the answer. A motivated student can study each step, but a tired one can simply copy it, so parents who worry about that should pair it with a tutor that asks questions first, such as Khanmigo or ChatGPT's study mode.

    What it does well

    • +Free plan already shows step-by-step explanations
    • +Covers elementary math through calculus and statistics
    • +Annual plan works out cheaper than monthly

    Quoted from the Synthesis Tutor pricing page on November 12, 2026: $119 billed annually, equal to $9.92 per month

    Synthesis Tutor is the only tool here built for young children, and it treats math as a series of interactive lessons rather than a chat. The company says it is designed for ages 5 to 11 and covers the standard K-5 math curriculum, from counting and cardinality to fractions and algebraic thinking. The tutor adapts as the child works, surfaces mistakes and targets gaps in knowledge, while parents get progress reports. One family plan covers up to 7 children, which makes it cheaper per child than most apps: $119 billed annually, which Synthesis says equals $9.92 per month, or $29 billed monthly. A 7-day free trial starts without a credit card. The tradeoff is scope. It does not help with a specific worksheet a teacher sent home, it stops at elementary math, and older students will outgrow it quickly.

    What it does well

    • +One price covers up to 7 children

    Quoted from the Mathos AI pricing page on November 12, 2026: Basic Handles everything you'll actually throw at it. $ 5.98

    Mathos AI is a math solver that tries to act like a tutor. You can ask it for a single nudge or the full worked solution, and it can turn any solution into a quiz, a flashcard deck or a short animated video. Its adaptive learning feature looks at the pattern behind a missed question, works on the missing prerequisite, and then brings the learner back. The free plan needs no card and includes 6 video minutes a day, limited image input and flashcards and quizzes. Paid plans are billed weekly: Basic at $5.98 and Prime at $9.98 per week, with a 3-day free trial. Weekly billing is the main drawback, because a month of Basic costs more than ChatGPT Plus. It is a good fit for a student who learns from video during a hard unit, less so as a year-round subscription.

    What it does well

    • +Free plan needs no card
    • +You choose a hint or a full worked solution
    • +Video explanations generated for your own problem

    Brainly has moved from a question and answer site to a homework and test prep platform aimed at parents of 7th to 12th graders. A student uploads their own homework, picks a solving method, and Brainly breaks the problem into steps, keeping the next step locked until the current one is right, so a correct answer cannot be reached by accident. Its Test Prep feature turns the topics a student missed into practice questions and a study guide before an exam. Every plan includes a learning advisor, a real person who sets up the account and tells parents what matters, and families can add a weekly hour with a vetted human tutor. Brainly offers a 30-day money-back guarantee. We could not confirm a US price from its pages, so the entry is marked as pending, and its parent-first design makes it a poor fit for college students or adults learning on their own.

    Quoted from the Tutor AI pricing page on November 12, 2026: Mentor $ 13.33 / Month

    Tutor AI is built for people who want to learn a whole topic rather than finish one assignment. You tell it what you want to learn and it generates a personalized course with lessons, quizzes, flashcards and study materials, then tracks your progress. Topics range from machine learning to intermediate French to workplace skills, and there is also a homework helper that returns step-by-step solutions to uploaded questions. The free plan needs no payment. The Mentor plan, listed at $13.33 per month on yearly billing, adds 100+ on-demand courses and unlimited chat, and Genius at $17.50 per month adds 1000+ courses with a spaced repetition dashboard. The courses are generated by AI, not written or checked by teachers, so accuracy depends on the model, and the tool has no parent controls. It suits motivated adults and college students more than children.

    Chegg Study is the oldest service on this list and the most answer-focused. Its main asset is a library that Chegg says holds 85+ million step-by-step explanations, Q&As and math support, which is useful when a college course follows a common textbook. The subscription also includes a Math Solver, a Study Planner and writing tools for plagiarism checks, expert proofreading and citations. Help is available 24/7. For learning, the model is weaker than the AI tutors above: it leads with a worked solution rather than questions, so it works best for checking your own attempt, not for building understanding from scratch. Chegg did not show a US price on the pages we could load, and its plans page blocked our check, so the price is marked as pending. Most high school students will get more from the free plans of ChatGPT or Gemini.

Before you pick a product or a plan

Decide between a tutor and a solver

Khanmigo, ChatGPT's study mode and Brainly ask questions and hold back the answer so the student does the thinking. Photomath, Mathos AI and Chegg Study show a worked solution first, which is faster for checking work but easier to copy. Pick the first type for learning and the second for checking.

Start with what is free

ChatGPT's study mode, Gemini, Photomath Basic, Mathos AI and Tutor AI all have permanent free plans. Synthesis Tutor has a 7-day free trial and Mathos AI paid plans a 3-day trial. Try a free plan for a week of real homework before paying.

Match the tool to the age

Synthesis Tutor is built for ages 5 to 11 and the K-5 math curriculum. Brainly is aimed at parents of 7th to 12th graders. Khanmigo spans school subjects with a parent account, while ChatGPT, Gemini, Tutor AI and Chegg Study suit high school, college and adult learners.

Compare the real monthly cost

Khanmigo costs $4 per month and Google AI Plus $4.99. Photomath Plus is $9.99 per month or $69.99 per year, and Synthesis Tutor is $119 per year for up to 7 children. Mathos AI bills weekly at $5.98 or $9.98, which adds up to more than ChatGPT Plus at $20 per month.

Check school rules and parent controls

OpenAI tells students to follow their school's AI-use policies for graded work. If a child will use the tool alone, Khanmigo's family plan shows chat history and sends moderation alerts, and Brainly assigns a learning advisor who reports to parents.
