Quick Answer: Best Homework Help Websites
The best homework help websites are the ones that teach you the method, not just the answer. Start with free options: Khan Academy for lessons in nearly every school subject, Desmos for graphing, Purdue OWL for writing and your public library for free tutoring. Add a paid site only when free ones are not enough, such as Tutor.com for live help or Wyzant to pick your own tutor. Below are 25 sites sorted by price and subject, plus a safe way to use them without breaking your school's rules. For AI-powered study helpers, see our main guide to the best AI tools for students.
Every student gets stuck on homework sometimes. A math problem will not make sense, an essay will not start, or a science concept sounds like another language. When that happens at 9 p.m., you want help that is quick, reliable and does not cost a fortune.
This guide covers the best homework help websites for 2027, grouped by cost and by subject. We include free sites, freemium sites with paid upgrades, and paid tutoring services, along with honest notes on what each one does well and where it falls short. We also explain how to use these sites so you actually learn, which matters for your grades and for staying on the right side of school rules.
The guide is written for students in the United States, United Kingdom, Australia and Canada, and it works for parents who want to find the right support for a teen.
How to Choose a Homework Help Website
The best site depends on what is stopping you. Before you open another tab, work out which of these problems you have.
You do not understand the concept. You need lessons and examples, not answers. Pick a site with videos or step-by-step teaching, such as Khan Academy, Crash Course or CK-12.
You understand it but need practice. You need problems with instant feedback. Khan Academy, Quizlet and Desmos are strong here.
You are stuck on one specific problem. A step-by-step solver or a tutor can unblock you. Use a math solver to see the steps, then redo the problem yourself without looking.
You need a person. Live tutoring on Tutor.com or Wyzant is better than any app when you need to ask follow-up questions.
You are on a budget. Start free. Between Khan Academy, your public library and a handful of free tools, most students never need to pay. If you are looking for a cost-free option that suits your situation, the sections below flag what is free and what is not.
Whatever you choose, aim for sites that show how to get to the answer. If a site only gives final answers with no explanation, you will be stuck again on the next test.
Free Homework Help Websites (1 to 10)
These sites are free to use for core features. They are the best place to start.
1. Khan Academy
Khan Academy is the best free homework help website for most students. It is run by a non-profit and offers video lessons, practice exercises and progress tracking in math (from early grades through early college), science, economics, history and computer programming. It also includes free test prep for exams such as the SAT. Short lessons make it easy to fix a specific gap, such as fractions, quadratic equations or the causes of World War I.
Best for: learning a concept from scratch. Cost: free. Watch out: it does not cover every subject, such as art or music, and it will not solve your specific worksheet for you.
2. CK-12
CK-12 is a free education non-profit that offers digital textbooks, interactive simulations and practice for math and science. Its content is organized by topic, so you can jump to exactly what you need, and many teachers assign it directly. It is a good alternative when your school textbook is confusing.
Best for: middle and high school math and science. Cost: free. Watch out: it can feel text-heavy compared with video-based sites.
3. PhET Interactive Simulations
PhET, from the University of Colorado Boulder, offers free interactive simulations for physics, chemistry, biology, earth science and math. Instead of reading about circuits or gas laws, you can change the variables and watch what happens. It is excellent for the “I read the chapter but still do not get it” problem.
Best for: visual and hands-on science learning. Cost: free. Watch out: it teaches concepts, not worksheet answers.
4. Desmos
Desmos is a free online graphing calculator that is simple to use and works in any browser. You can plot equations, explore functions and see how changing a number affects a graph. Many schools and exams that allow graphing calculators also allow or mirror Desmos, so it is a useful tool to learn.
Best for: algebra, functions and graphing. Cost: free. Watch out: it graphs and calculates, but it does not teach the method by itself.
5. Purdue OWL
The Purdue Online Writing Lab is one of the most trusted free resources for writing help. It explains grammar, essay structure, thesis statements, research papers and citation styles such as MLA, APA and Chicago. If a teacher asks for a certain format, Purdue OWL will almost always explain it clearly.
Best for: essays, citations and grammar. Cost: free. Watch out: it is a reference guide, not a place to get feedback on your own draft.
6. Your Public Library’s Homework Help
Many public libraries offer free homework help to cardholders, and the service is often overlooked. Depending on where you live, this may include live online tutoring, access to study databases, practice tests and e-books. You usually only need your library card number to log in. Check your library’s website under “homework help”, “students” or “online resources”.
Best for: free live help and trusted databases. Cost: free with a library card. Watch out: services and hours differ by library, so check yours.
7. Crash Course (YouTube)
Crash Course is a free YouTube channel network that explains subjects such as biology, chemistry, US and world history, economics, literature and computer science in fast, entertaining videos. It is ideal for getting the big picture before a test or for a topic you find dull in class.
Best for: quick overviews and revision. Cost: free. Watch out: videos move quickly, so pause and take notes.
8. MIT OpenCourseWare
MIT OpenCourseWare publishes materials from real university courses for free, including lecture notes, problem sets and sometimes videos. It is demanding, but it suits advanced high school students and college students who want depth in calculus, physics, programming and more.
Best for: advanced and college-level study. Cost: free. Watch out: it assumes you can learn independently.
9. freeCodeCamp
freeCodeCamp is a non-profit that teaches web development, data and programming through free, hands-on lessons and projects. It is useful for computer science homework and for learning to code beyond what school offers.
Best for: coding practice. Cost: free. Watch out: it follows its own curriculum, so it may not match your class assignments.
10. Microsoft Math Solver
Microsoft Math Solver is a free tool that shows worked, step-by-step solutions for algebra, trigonometry, calculus and more, and you can type or photograph a problem. Used well, it is a way to check your method after you try a problem yourself.
Best for: checking math steps. Cost: free. Watch out: do not copy answers without understanding them, and check your teacher’s rules on solvers.
Freemium Apps and Websites (11 to 18)
These sites have a useful free version, with optional paid upgrades for extra features.
11. Quizlet
Quizlet is the best-known flashcard site, with millions of student-made study sets for almost every subject. It offers flashcards, matching games and practice modes. The free plan covers the basics, and a paid plan adds more practice and study tools. Prices change, so check Quizlet’s site before you subscribe.
Best for: vocabulary, definitions and exam revision. Cost: free plan plus paid upgrade. Watch out: user-made sets can contain mistakes, so check against your textbook.
12. Brainly
Brainly is a community Q&A site where students ask questions and others answer. It works well for quick explanations and different ways of seeing a problem. It has a free level with limits, plus a paid option for extra features. Treat community answers as a starting point and double-check them.
Best for: quick explanations from other students. Cost: free with paid upgrade. Watch out: answers vary in quality.
13. Photomath
Photomath lets you scan a math problem with your phone camera and shows steps. The basic features are free, and a paid plan adds more detailed explanations. It is most useful when you have already tried a problem and want to find out where you went wrong.
Best for: checking math homework steps. Cost: free basics, paid upgrade. Watch out: reading steps is not the same as learning them, so re-do each problem on your own.
14. Wolfram Alpha
Wolfram Alpha is a computational engine that answers math, science, statistics and unit questions. The basic version is free, while detailed step-by-step solutions are part of a paid plan. It is helpful for checking calculations and exploring data.
Best for: advanced math and science checks. Cost: free basics, paid steps. Watch out: the interface assumes you know what to ask.
15. Grammarly
Grammarly checks spelling, grammar and clarity as you write. The free version catches the most common mistakes, and paid plans add deeper suggestions. It helps you polish your own writing and learn from corrections. Some schools have rules on writing tools, so check yours before relying on its generative features.
Best for: proofreading essays. Cost: free plan plus paid upgrade. Watch out: it improves your writing but does not replace the thinking.
16. Duolingo
Duolingo turns language learning into short daily lessons. It is a good supplement for Spanish, French, German and many other languages and helps with vocabulary and habit-building. The core app is free with ads, and a paid plan removes limits.
Best for: daily language practice. Cost: free with ads, paid option. Watch out: it will not fully prepare you for a grammar-heavy class exam on its own.
17. Symbolab
Symbolab is a math solver and learning tool for algebra, calculus and beyond, with free and paid features. It is similar to Photomath but works well on a computer for typing longer expressions.
Best for: checking higher-level math. Cost: free basics, paid steps. Watch out: the same advice applies: solve it yourself first.
18. Coursera
Coursera offers university and company courses online. Many can be taken for free without a certificate, and paying is optional if you want graded work or a credential. It suits older students who want to go deeper than their class in subjects like statistics, programming and psychology.
Best for: college-level and advanced topics. Cost: free to audit many courses, paid for certificates. Watch out: course quality and free access vary.
Paid Homework Help and Online Tutoring (19 to 25)
Paid services make sense when free sites have not worked, you need personal attention or a deadline is close. Prices below are rough, so check each site before booking.
19. Khanmigo
Khanmigo is Khan Academy’s AI tutor. It is designed to guide students toward answers with questions and hints instead of simply giving the answer, which makes it one of the more homework-friendly AI tools. It is a paid add-on, at a low monthly cost compared with human tutors.
Best for: AI help that teaches. Cost: low monthly fee. Watch out: it is an AI, so check anything important against your textbook or teacher.
20. Tutor.com
Tutor.com provides on-demand online tutoring at any hour, which is useful for last-minute homework. In some regions, libraries, schools and other organizations provide free access, so check before you pay. It is a strong fit when you need a person to explain something now.
Best for: instant, live homework help. Cost: paid per session or plan, sometimes free through libraries or schools. Watch out: quality depends on the tutor you get.
21. Wyzant
Wyzant is a marketplace where tutors set their own rates and you choose based on reviews, subject and price. That flexibility makes it good for specialist subjects and one-off sessions. You pay per lesson with no long contract.
Best for: choosing your own tutor. Cost: varies by tutor. Watch out: rates range widely, so compare several tutors and use trial lessons if offered.
22. Varsity Tutors
Varsity Tutors is a managed service that matches you with a tutor and often sells lesson packages. It suits families who want someone else to handle the matching, though packages can be a significant commitment.
Best for: a hands-off, structured tutoring plan. Cost: usually the highest of the group. Watch out: read the package terms and refund policy carefully before you pay.
23. Preply
Preply is mainly for language learning, with tutors from many countries and a wide price range. It is a good fit for Spanish, French, English and exam prep such as IELTS or TOEFL, and you can often start with a short trial lesson.
Best for: language tutoring. Cost: varies by tutor. Watch out: it is less suited to general school subjects like chemistry.
24. Superprof
Superprof is a directory where you contact tutors directly. It covers school subjects plus music, art and other skills, and many tutors offer a free first lesson. It is good for finding local or niche tutors.
Best for: variety and local tutors. Cost: set by each tutor. Watch out: you arrange payment and terms yourself, so be careful about personal details.
25. Chegg Study
Chegg Study offers textbook solutions, expert Q&A and extra study tools on a monthly subscription. It is among the best-known paid homework help services. Use it to understand worked solutions and compare methods, not to copy answers into graded work, which most schools treat as cheating.
Best for: textbook problem solutions. Cost: monthly subscription. Watch out: it is not cheap, and using it to submit answers you do not understand can get you into trouble.

How to Use Homework Help Websites Honestly
Using these sites is not cheating. Copying answers you do not understand and handing them in as your own work is. Here is a simple rule: you can use a site to learn how to do something, but you should be able to do the next similar problem without it.
Try first. Spend at least ten minutes on a problem before looking anything up. Even a wrong attempt helps you understand the explanation when you find it.
Learn the method, then redo it. After reading a solution, close it and solve the problem again from scratch. If you cannot, you have not learned it yet.
Follow your school’s rules. Policies on solvers, AI and online help differ between schools and teachers. If you are not sure, ask. Our guide on whether teens can rely on AI and our article on AI and teen responsibility go deeper on using AI honestly.
Be wary of “we do it for you” services. Some websites advertise paying someone to complete your assignments or essays. This is academic dishonesty, it can lead to serious consequences at school, and the quality is often poor. Choose sites that explain and teach.
Homework Tips That Make Any Site Work Better
Plan your week. A simple list of what is due and when stops last-minute panic. Our printable Homework & Study Planner includes a weekly homework tracker, a due-date list and a study schedule.
Break big tasks down. Split an essay or project into small steps with their own deadlines. If you often delay, our guide on procrastination and our tips to improve focus naturally can help.
Use short, focused sessions. Work for 25 minutes, then take a five-minute break. Put your phone in another room.
Take care of yourself. Homework stress is real. If it is getting to you, read our guides on how to calm anxiety fast and teenage stress.
Tips for Parents Choosing Homework Help
If you are a parent looking for support for your teen, you do not have to buy the most expensive option. Start by asking your teen what exactly is hard, because the answer decides the tool. Free options such as Khan Academy and your library’s homework help are often enough, and you can add paid tutoring later if needed.
Try to help without doing the work for your child. Ask them to explain the problem to you, sit nearby while they work and celebrate effort over perfect answers. When you look at paid services, ask for a trial lesson, read the cancellation terms and avoid long prepaid packages until you know the tutor is a good fit.
If homework is consistently overwhelming, talk to the teacher. There may be a simple fix, such as adjusting the workload or finding school support. Our broader guide for families, AI and Teens: The Complete Parent and Teen Guide, covers how to handle technology and study together.
Safety and Privacy When Using Homework Websites
Many homework sites require you to create an account, and some are meant for older users. Check each site’s age rules, and if you are under the minimum age, use it with a parent or guardian. Do not share your full name, address, school name or photos of yourself in public question boards. When you upload a photo of a worksheet, check that it does not show personal details. Use a strong, unique password, and be careful with any site that asks for payment details upfront or promises guaranteed grades.
