Search "best homework help websites" and you'll find a dozen listicles that rank the sites nobody at the site in question has actually used, with affiliate links where the reasoning should be. This is not that list.
Here's our bias up front: we make Scrny, an AI screenshot answer tool, and it appears below. It's genuinely the best pick for one specific job — and the wrong pick for several others, where we'll point you at a competitor instead. Every entry here earns its spot for a particular kind of student on a particular kind of night.
How to actually judge a homework help site
Four questions separate useful from useless:
- Does it explain, or just answer? An answer you can't defend in class is a liability on exam day.
- How fast is it when you're stuck right now? A community that replies in six hours doesn't help with an assignment due in two.
- Can it read your actual problem? Typing a definite integral or a circuit diagram into a text box is its own homework.
- What does "free" cost? Ads, capped answers, locked steps, or your data — someone is paying for the servers.
With that lens, here's the field.
Free reference and structured learning
Khan Academy — best for learning a concept from zero
A nonprofit with full video courses, practice exercises, and mastery tracking across math, science, economics, and more. If your problem is "I don't understand what a derivative is," nothing on this list beats working through the Khan sequence — it's patient, sequenced, and completely free with no catch.
The trade-off is time and specificity: Khan teaches the topic, not your problem. There's no way to hand it question 7 from your worksheet. That's a feature for learning and a limitation at 11 PM. (We wrote a fuller comparison in Scrny vs Khan Academy — short version: they're complements, not competitors.)
Wolfram Alpha — best for raw computation
A computational knowledge engine, not a chatbot: feed it an equation, integral, matrix, or unit conversion and it computes the result symbolically. For pure math it is extraordinarily reliable, and the basic engine is free (step-by-step solutions sit in the paid Pro tier).
The trade-off: you must translate your problem into Wolfram's input syntax, which for anything with notation gets fiddly fast, and it won't help with conceptual, multiple-choice, or written questions at all.
Q&A communities
Brainly — best for common textbook questions
A huge student community where questions get answered by other students and moderators. Because the user base is enormous, popular textbook problems are often already answered. It runs freemium — expect ads and locked answers pushing you toward the paid tier.
Quality is the gamble: answers come from people whose own grasp of the material varies, and for anything past standard problems, the miss rate climbs.
Reddit's r/HomeworkHelp — best free human explanation
Genuinely free, no ads-with-answers model, and the volunteer explainers who hang out there are often excellent — many will refuse to hand you a bare answer and walk you through the method instead, which is exactly what you want.
The trade-off is turnaround and coverage: you're posting into a queue of strangers with no SLA. Great for "I have until tomorrow," useless for "I have until 10 PM."
Human tutoring
Wyzant — best for sustained one-on-one help
A marketplace of independent tutors who set their own hourly rates; you browse by subject, read reviews, and book sessions. For a subject you're going to struggle with all semester, a standing weekly session with one human who knows your gaps beats every tool on this list.
The trade-offs are the obvious ones: it's by far the most expensive option here, and it's scheduled help — not on-demand.
Your school's own tutoring center — best value, period
Before paying anyone: most schools and universities run tutoring centers, writing centers, and instructor office hours you've already paid for with tuition. Office hours are also the only "homework help" that directly signals effort to the person grading you. Underused everywhere.
AI answer tools
Photomath — best for phone-camera algebra
Point your phone at an equation and it solves with animated steps. For the algebra-through-calculus band it's polished and fast, and the core scanning is free with a paid tier for deeper explanations. If your homework is a printed math worksheet and your device is a phone, it's an excellent pick — honest comparison in Scrny vs Photomath.
It's math-only, though: no multiple choice, no science reasoning, no code.
ChatGPT — best generalist
The strongest general-purpose AI for discussing homework: rephrase a concept five ways, quiz you, critique your essay outline. Free tier available, paid tiers for the stronger models.
Its weakness for homework specifically is input and focus: you type or paste (screenshots of complex layouts get inconsistent treatment), and it answers everything — with no workflow built around checking, explaining, and moving to the next question. We compared directly in Scrny vs ChatGPT.
Scrny — best for on-screen questions (ours)
Our tool, so judge accordingly — here's exactly what it is. Scrny reads a screenshot: quiz questions, equations, diagrams, code errors, handwriting, PDFs. You capture the question, it returns the answer in about 2.4 seconds with the full working one tap away — on multiple choice, it explains why each wrong option is wrong. On standard practice-exam MCQ banks (AZ-900, AWS Cloud Practitioner, CompTIA, CCNA prep) it tests at 99% accuracy.
It is deliberately not free: plans are $1.99/month for 15 answers, $5.99 for 200, or $7.99 for 500, cancel anytime — every answer is a real vision-model call, and the $1.99 entry buys out the ads and answer-caps that "free" tools use to pay for themselves. It's also screenshot-based on purpose: nothing runs in the background watching your screen. If your questions live on paper and you'd rather type, several picks above serve you better.

Match the site to the night
- "I don't understand this topic at all" → Khan Academy now, office hours this week.
- "I need this one computation checked" → Wolfram Alpha.
- "It's due tomorrow and I want a human" → r/HomeworkHelp tonight, Wyzant if it keeps happening.
- "The question is on my screen and I'm stuck right now" → Scrny, or Photomath if it's typed math on paper.
- "I want to talk it through" → ChatGPT, then verify anything that matters.
Most students end up with a two-tool stack: one for learning (Khan, a tutor, office hours) and one for unsticking (a screenshot or camera tool). If you're deciding on the second kind, our honest look at the whole AI category is in the best AI homework helper guide — competitors included.
