The Research Score rates each product on its own merits. Our picks also weigh price and who the product is for, so a pick can rank above a higher-scoring product. How we score

The best AI tools for students don’t do your homework. They help you understand the material: turning lecture notes into quizzes, explaining a concept a different way, walking you through a math problem one step at a time, and finding sources you can actually cite.

For most students, Gemini Notebook (Google renamed NotebookLM in July 2026) is the place to start. It’s free with a Google account, and it bases its answers on the sources you add, from lecture notes to readings, so you can build flashcards, quizzes and audio summaries from your own course materials. ChatGPT’s study mode, free on every plan, is our runner-up for tutor-style help. Gemini is our budget pick, especially for eligible US college students, who can get a year of Google AI Pro free if they redeem by December 31, 2026. Perplexity is best for research with citations, and Khanmigo is an inexpensive, guided tutor for math and other subjects.

Schools’ AI policies vary, so check yours before you use any of these for graded work. We based these picks on official pricing, help-center and privacy pages. We did not test these tools hands-on.

Why you should trust us

We considered ten AI tools for students: Gemini Notebook (formerly NotebookLM), ChatGPT, Gemini, Perplexity, Khanmigo, Photomath, Quizlet, Grammarly, Claude and QuillBot. For each, we read official pricing pages, help-center articles, student-offer terms and privacy pages, all checked on the date of publication. We list student discounts only when we could confirm them on official pages, with eligibility rules and end dates. We scored picks with our published Research Score where the sources allowed it. We did not run hands-on tests for this guide.

Who this is for

This guide is for high school, college and graduate students who want AI help with studying: reviewing notes, preparing for exams, getting unstuck on homework and finding sources. If you mainly want help with essays and papers, see our guide to the best AI writing tools for students.

Use AI to learn, not to submit

AI policies vary by school and by instructor. Some ban AI tools, some allow them for studying but not for graded work, and some require you to disclose any use. Check your syllabus and ask when in doubt.

The tools we picked are most useful, and least risky, when they help you learn: quizzing you, explaining a concept, finding sources, showing the steps of a problem. Submitting AI-generated answers or text as your own is the use most likely to break the rules, and it skips the learning you’ll need on the exam.

Don’t rely on AI detectors to settle the question, either. OpenAI says that in its research, detectors weren’t reliable enough given the lasting consequences for students, sometimes labeled human-written text as AI-generated, and showed signs of disproportionately affecting students learning English as a second language.

How we picked

We looked for tools that:

  • Help you learn rather than just answer, with tutoring, guided questions, quizzes or step-by-step explanations.
  • Work with your own materials, such as notes, slides, syllabi and readings.
  • Are free or cheap, with verified student discounts where they exist.
  • Show their sources when you’re doing research.
  • Are clear about your data, including whether your chats train their AI.
  • Run where you study: web, iOS and Android.

Gemini Notebook (formerly NotebookLM)

8.3/10

Gemini Notebook answers questions using only the sources you give it and turns them into flashcards, quizzes and podcast-style Audio Overviews, and its free tier allows 100 notebooks with up to 50 sources each.

Gemini Notebook is our top pick because it works the way studying should: from your own materials. Google says the tool’s advantage is being source-grounded, meaning it answers based on the documents you provide, which it says reduces the risk of AI errors and hallucinations. Upload your lecture notes, slides and readings, and you can ask questions about them, generate summaries, or have it build flashcards and quizzes for an exam. It can also create a podcast-style Audio Overview of your sources, useful for reviewing on a commute.

If you’ve used NotebookLM, nothing is lost. Google’s FAQ says NotebookLM became Gemini Notebook in July 2026, that it’s the same product, and that existing notebooks remain accessible on web and mobile.

The free Standard tier is generous for most students. Google’s help center lists 100 notebooks per user and up to 50 sources per notebook, free with a Gmail account. Google AI Plus raises that to 200 notebooks and 100 sources; Google AI Pro or a qualifying Workspace for Education license raises it to 500 notebooks and 300 sources. Google notes that these limits are subject to change.

Flaws but not dealbreakers

Gemini Notebook only knows what you give it, so it’s not the tool for exploring a new topic from scratch; pair it with Perplexity or a chatbot for that. Google’s FAQ also says there’s currently no recovery option for deleted notebooks, so keep your original files.

On privacy, Google says it does not use content from individual users for training generative AI models unless they share feedback, and that Workspace users’ uploads, queries and responses aren’t used for training even if they send feedback. That’s a better default than most chatbots.

Who it’s for

Students who want to study from their own lecture notes, readings and slides rather than from the open web.

Who should skip it

You need help with topics you don't have materials for, or step-by-step math tutoring.

Pros

  • Free with a Google account: 100 notebooks, up to 50 sources each
  • Answers grounded in your sources, which Google says reduces AI errors
  • Flashcards, quizzes and podcast-style Audio Overviews
  • Google says individuals' data isn't used for training unless they send feedback

Cons

  • Only as good as the sources you upload
  • Deleted notebooks can't be recovered
  • Higher limits require a Google AI plan or a qualifying Workspace for Education license

ChatGPT

8.1/10

ChatGPT’s study mode, free on every plan, asks guiding questions, explains step by step and quizzes you on uploaded notes, and eligible US college students could claim four free months of Plus through October 31, 2026.

ChatGPT’s study mode turns the chatbot into something closer to a tutor. OpenAI says it is available across ChatGPT plans globally on web, iOS and Android, and that instead of only giving a final answer it can ask questions, guide your thinking, explain ideas step by step and check your understanding. You can ask it to quiz you one question at a time, create practice questions or flashcard-style review, or explain why an answer is right or wrong.

It works with your materials, too: OpenAI lists class notes, a syllabus, worksheets, slides, textbook excerpts and photos of math or science problems as things you can upload. On the web, you turn it on by typing @study in the message box or by going to chatgpt.com/studymode. OpenAI’s help article reminds students to follow their school’s or instructor’s AI policies for graded work.

Eligible US college and graduate students can also claim OpenAI’s 2026 Back to School offer: four free monthly billing periods of ChatGPT Plus, verified through SheerID. It must be claimed by October 31, 2026, requires a payment method, and renews at $20 a month unless you cancel.

Flaws but not dealbreakers

Study mode uses the same plan limits as regular ChatGPT, so it doesn’t add messages or unlock models. It’s not available in Temporary Chats, GPTs or Projects. OpenAI also cautions that it can make mistakes and may sometimes give a direct answer; you can ask it to stick to hints instead.

On personal Free, Plus and Pro accounts, “Improve the model for everyone” is on by default; turn it off under Settings > Data controls if you don’t want your chats used for training.

Who it’s for

Students who want an always-available tutor for homework help, exam review and explanations.

Who should skip it

You want your chats kept out of model training without changing a setting.

Pros

  • Study mode on all plans, on web, iOS and Android
  • Quizzes, practice questions and flashcard-style review from your uploads
  • Free plan includes unlimited everyday text chats
  • Four free months of Plus for eligible US college students (claim by Oct. 31, 2026)

Cons

  • Chats can train OpenAI's models by default on personal plans; opt-out required
  • Study mode isn't available in Projects, GPTs or Temporary Chats
  • Can still make mistakes and sometimes gives direct answers

Gemini

7.8/10

Gemini’s Guided Learning acts as a tutor with practice questions, hints and diagrams, its free tier includes Deep Research, and eligible US college students 18 and older can get Google AI Pro free for a year.

Gemini has its own tutor mode. Google’s help center says Gemini can act as a tutor using Guided Learning, visual aids and educational resources. You can add files or images, ask for practice questions with feedback and hints in multiple-choice or open-ended form, and request a diagram. Typing @OpenStax draws on OpenStax textbooks, though Google says that feature is available only in English, in the United States, and not to users under 18 or on school accounts.

Google’s US plans page lists Deep Research, image generation and Gemini Notebook on the free tier, with Google AI Plus at $4.99 a month and Google AI Pro at $19.99 a month. For eligible US college students aged 18 and older, Google’s student page offers AI Pro free for one year if redeemed by December 31, 2026. Google lists 4x higher Gemini usage limits, 5 TB of storage, personalized quizzes built from your notes, a performance tracker, study notebooks for each course and a learning plan generated from your uploaded materials.

Flaws but not dealbreakers

The free student year requires a payment method, renews at $19.99 a month unless you cancel, and must be re-verified every year. Google’s Gemini privacy hub says that when Keep Activity is on, chats help train Google’s AI models and some are reviewed by people, with reviewed chats kept for up to three years. You can turn Keep Activity off; Google still keeps chats for 72 hours. Google also notes that its learning tools are rolling out gradually in the mobile app.

Who it’s for

Students on a budget, especially US college students who can claim the free AI Pro year.

Who should skip it

You don't want some chats reviewed by people, or you're under 18 and want the student plan.

Pros

  • Guided Learning with practice questions, hints and visual aids
  • Free tier includes Deep Research and Gemini Notebook
  • Free year of Google AI Pro for eligible US college students (redeem by Dec. 31, 2026)
  • Student plan adds quizzes from your notes and per-course study notebooks

Cons

  • Some chats are reviewed by humans when Keep Activity is on
  • Student plan renews at $19.99/month and needs yearly re-verification
  • OpenStax textbook features are US-only, English-only and 18+

Perplexity

Perplexity answers questions with linked sources, and verified students and educators can get Education Pro, which includes everything in Pro plus Learn Mode, at a discount.

Perplexity works like a search engine that writes answers and shows where they came from, which makes it a useful first step for research: you can open the sources, judge them and cite the ones that hold up. Perplexity’s help center says its Education Pro plan is offered to verified students and educators at a discount and includes everything in Pro, including Learn Mode, unlimited Pro Searches, file and image uploads and premium models, plus education-specific tips. Verification runs through SheerID; in the app, you choose Upgrade, switch to the Education plan and select “Verify as student.” Perplexity says Pro offers 10x as many citations per answer.

Flaws but not dealbreakers

Perplexity’s help article doesn’t give a price for Education Pro, and we couldn’t confirm US pricing for its plans on official pages, so check the upgrade screen before paying. Perplexity’s help center also says it uses your searches to improve its AI unless you turn off the AI Data Usage toggle in Settings. And citations aren’t a guarantee: read the source before you cite it.

Who it’s for

Students starting a research paper who need sources they can open, read and cite.

Who should skip it

You want to study from your own notes; Gemini Notebook is better for that.

Pros

  • Answers come with citations; Pro adds 10x as many per answer
  • Education Pro discount for verified students and faculty
  • AI Data Usage toggle to opt out of training

Cons

  • We couldn't confirm US prices for Pro or Education Pro on official pages
  • You still need to read and check every source it cites

Khanmigo

Khan Academy’s Khanmigo guides students toward answers instead of giving them away, covers elementary school through college, and costs $4 a month or $44 a year for learners and families.

Khanmigo comes from Khan Academy, which describes itself as a donation-funded education nonprofit. Its site says that, unlike general chatbots, Khanmigo doesn’t just give answers but guides learners toward finding them, and that it can help students from elementary school through college in subjects including math, science, coding, history and the humanities.

It’s also the cheapest paid tool here: Khanmigo’s pricing page lists $4 a month or $44 a year for learners and families, before sales tax, and teacher tools are free. Parents can enable access for up to 10 children under 18 from one parent account.

Flaws but not dealbreakers

Khanmigo is US-only for now: its site requires US residence and a US billing address, and subscribers must be 18 or older. Students can’t get access through a teacher’s account; classroom access comes through school or district arrangements. We couldn’t find enough detail on its data practices on the pages we reviewed to score it.

Who it’s for

Families and learners who want an inexpensive tutor built to avoid handing out answers.

Who should skip it

You live outside the US or want a general-purpose assistant for writing and research.

Pros

  • Built to guide learners rather than hand over answers
  • $4/month or $44/year; parents can add up to 10 children under 18
  • Free for teachers

Cons

  • Requires US residence and a US billing address
  • Subscribers must be 18 or older; younger students need a parent account

Other good options

Photomath is a dedicated math helper. You scan a problem with your phone, including word problems, or type it into its calculator, and it shows step-by-step explanations, covering elementary math, algebra, geometry, trigonometry, statistics and calculus, from elementary school through college. Its site lists a free Basic plan and paid plans at $9.99 a month or $69.99 a year at the time of research, both with a free trial. It’s available on the App Store and Google Play. Because it shows full solutions, it works best for checking your work and seeing where you went wrong, not for copying answers.

Grammarly, Claude and QuillBot are strong for writing feedback, editing and summarizing readings. We cover them in the best AI writing tools for students.

The competition

Quizlet: Quizlet is a familiar flashcard and study platform with paid Plus tiers. We couldn’t confirm its US pricing or current AI features on official pages at the time of research, so we didn’t include it. For AI-generated flashcards and quizzes from your own notes, Gemini Notebook and ChatGPT’s study mode are free alternatives.

What to look forward to

Student offers come and go with the school calendar. OpenAI’s four free months of ChatGPT Plus must be claimed by October 31, 2026, and Google’s free year of AI Pro must be redeemed by December 31, 2026. Google also says Gemini’s learning tools are still rolling out gradually in its mobile app. We’ll update this guide as offers end or new ones appear.

FAQ

What is the best free AI tool for students?

Gemini Notebook is the best free tool for studying your own course materials, with 100 notebooks and up to 50 sources each on the free tier. ChatGPT’s study mode is also free on every plan.

Which AI is best for studying for exams?

Upload your notes and readings to Gemini Notebook to generate flashcards and quizzes, or use ChatGPT’s study mode and ask it to quiz you one question at a time and explain what you get wrong.

What is the best AI for math homework?

For learning the steps, use a tool that guides you: Khanmigo, ChatGPT’s study mode or Gemini’s Guided Learning. Photomath shows step-by-step solutions to problems you scan or type, from elementary math through calculus.

Can teachers tell if you used AI?

Not reliably with detection software. OpenAI says AI detectors weren’t reliable enough in its research and sometimes flagged human writing as AI. The safest approach is to follow your class’s AI policy and disclose how you used AI.

Do students get AI tools for free?

At the time of research, eligible US college students could get Google AI Pro free for a year (redeem by December 31, 2026) and four free months of ChatGPT Plus (claim by October 31, 2026). Both renew at a monthly price unless you cancel.
