The Best AI Homework Helpers in 2026: An Honest Ranking of 8 Tools
Scholarly, Chegg, Course Hero, Photomath, Google Lens, Brainly, Mathway, and Symbolab ranked, with each free plan and limit re-checked in October 2026.
There is a real cognitive trade-off at the center of every "homework help" tool, and almost nobody selling one will name it out loud: looking up an answer and learning the concept are not the same activity. The first feels productive in the moment and leaves nothing in your head two weeks later, when the exam asks the same idea in slightly different clothes. The second feels slow, takes more reps, and is what actually moves your grade.
So the best AI homework helper is not the one that gets to the answer fastest. It's the one that gets you to the answer and leaves the underlying skill behind. Some tools below are excellent answer-lookups, a couple genuinely help you learn, and most are a mix. Each entry states its Free plan, Best for, and Limits, re-checked against the vendor's own site on October 20, 2026; we link pricing pages instead of quoting prices.
We rank Scholarly first because, on the learning-plus-answer axis, it's where we've put our effort, but every other tool here has a real use case, and several are free.
What to actually look for in an AI homework helper
- Step-by-step reasoning, not just a final answer. If the tool only gives you a number, you can't catch where your own approach went wrong.
- Handles your actual input. A photo of a handwritten problem, a PDF problem set, a typed equation, or a screenshot.
- Adapts the explanation to the concept you're missing. "I don't get the chain rule" needs a different response than "I made an arithmetic mistake at line 4."
- Generates practice from the same material. One worked example is forgotten; several variants are how the technique sticks.
- Doesn't pretend it can't be wrong. Especially on word problems, proofs, and chemistry.
- A free tier you can actually use at 11pm on a Sunday.
1. Scholarly: best overall for homework help that actually teaches
Scholarly's AI homework help takes a typed question, a photo, or a PDF or Word file of a problem set and returns step-by-step explanations you can question ("why do we square both sides at step 3?"). Because Scholarly is a source-grounded study workspace, the same material can then become AI flashcards on a spaced-repetition schedule, a practice test, or a short narrated video lecture on the concept. It handles non-math homework too: lab reports, literature and history questions, and computer-science problem sets.
Free plan: free signup with no credit card. A free account includes a small lifetime allowance of AI chat messages that does not reset, one lifetime file upload (8 MB; PDFs processed up to the first 32 pages), and one lifetime AI creation, such as a flashcard deck or practice test.
Best for: students who want to finish and understand an assignment across subjects, and turn the hard concept into practice.
Limits: the free allowances are lifetime, so Free is a trial of the workflow, not a semester of homework help. Premium ($30/month or $144/year in US dollars, regional prices in many countries) unlocks unlimited chat and 15 AI creations a week (see pricing). Photomath and Symbolab are faster when you just want the steps for one equation.
2. Chegg: best when your textbook's problems are already solved
Chegg's advantage is its library of expert-written textbook solutions and expert Q&A. For a specific problem from a specific edition, the expert solution can be more reliable than a general model.
Free plan: Chegg Study is sold as a paid subscription; check Chegg Study for current plans and any trial. We keep a breakdown of what Chegg costs.
Best for: upper-division engineering, physics, and economics courses whose textbooks are in Chegg's solutions library.
Limits: you're paying for the solutions library more than the AI, and the product is built around "the answer, fast," which makes it hard to use as a learning tool.
3. Course Hero: best for finding what other students wrote for the same course
Course Hero combines a library of course documents uploaded by students (study notes, past exams, assignments) with AI-powered answers and explanations and on-demand expert tutors.
Free plan: you can search the document library and browse answered questions on the site (see Course Hero); full documents come through document unlocks, and the homepage does not list plan prices.
Best for: course-specific case studies and assignments that have been given before.
Limits: academic-integrity risk is real; copying from a Course Hero document is something plagiarism detectors flag. Treat it as research input, not a draft.
4. Photomath: best for snap-a-photo math homework
Point your phone at a printed or handwritten problem, including word problems, and get a step-by-step solution.
Free plan: the Basic tier includes step-by-step explanations; custom visual aids and the extra "how" and "why" tips are on the paid plans (see Photomath).
Best for: algebra through early calculus problem sets where the problem is already written down.
Limits: it's math-only, and the custom visual aids and extra "how" and "why" tips are paid.
5. Google Lens homework help (formerly Socratic): best free option for one question at a time
Socratic, Google's free homework app, has been folded into Google Lens; socratic.org now leads to Lens, whose site advertises step-by-step homework help.
Free plan: free to use in the Google app, in Chrome, and in the camera app of select Android devices (see Google Lens).
Best for: high-school and early-college students with one question at a time.
Limits: it works one question at a time, with no multi-page problem-set upload and no flashcard or quiz layer.
6. Brainly: best for teens whose parents want visibility
Brainly has repositioned itself as an AI homework and test-prep platform for grades 7 to 12, sold to parents. Students upload their own homework, Brainly breaks problems into steps that unlock one at a time, and Test Prep turns what they missed into practice and a study guide. A learning advisor is included on every plan, and a weekly human tutor is an add-on.
Free plan: Brainly's homepage does not list a free plan; check Brainly for current plans.
Best for: families of middle- and high-school students who want guided steps plus a human check-in.
Limits: it is aimed at grades 7 to 12, not college coursework, and the human tutor costs extra.
7. Mathway: best for instant steps on a specific equation
Type or photograph an equation, pick the topic, and Mathway returns a solution.
Free plan: Mathway says it is free to use and gives step-by-step solutions without signing up; an optional subscription unlocks the full work for every step (see Mathway).
Best for: checking your work when you already understand the topic.
Limits: the full work for every step is on the optional subscription, and it solves the problem you enter rather than generating practice from your material.
8. Symbolab: best for showing every algebraic move
Symbolab's AI math solver breaks algebra, calculus, and trigonometry problems into steps and adds graphing, practice exercises, and an AI chat.
Free plan: the online solvers open without a subscription (see Symbolab); its homepage does not itemize which steps need Pro.
Best for: math majors and engineering students working integrals or differential equations.
Limits: Symbolab Pro, which its site now pairs with QuillBot writing tools, is the paid upgrade, and it is built around solving problems rather than generating practice from your course material.
A simple framework: when to use which
- You need to actually learn the material: Scholarly.
- Your textbook is in Chegg's solutions library and you can afford it: Chegg.
- You took a photo of a handwritten algebra or calculus problem and need the steps: Photomath or Symbolab.
- You want it free and have one question at a time: Google Lens.
- You want to see how other students handled the same course: Course Hero.
- You're a parent of a 7th to 12th grader who wants guided help and a human check-in: Brainly.
The part none of these tools can do for you is re-encountering the same idea several times across a week so that, when an exam asks it in a new shape, your brain produces the answer without help. That's the point of active recall and spaced repetition, and it's why the tools that also generate practice from the same material move your grade.
Frequently asked questions
Is using an AI homework helper considered cheating?
It depends on your institution's policy and how you use the tool. Using a helper to understand a concept and then doing your own work is generally fine; submitting AI-generated text or solutions as your own work is generally not. The safest pattern: learn the method, then re-solve the problem yourself from scratch before turning it in.
What's the cheapest paid AI homework helper?
Prices change often, so compare the current pricing pages for Mathway, Symbolab, Photomath, and Scholarly. Google Lens homework help is free.
Are AI homework helpers accurate?
Mostly, with caveats. Math-specific tools are very reliable on standard algebraic manipulation. General-purpose AI tools (including Scholarly and ChatGPT) are reliable on most topics but can be wrong on advanced proofs, novel word problems, or specialized chemistry. Verify the final answer against the back of the book or a second tool when stakes are high.
Can AI replace a tutor?
For most everyday problem sets, it can cover a lot. For deep conceptual gaps, where you don't know which question to ask, a human tutor is still better.
Which AI homework helper works best for chemistry?
A general-purpose tool such as Scholarly, which explains steps and can turn the topic into flashcards and a practice test. Photomath, Mathway, and Symbolab are built around math. Chegg's solutions library is strong for textbook problems in standard chemistry courses.
Can I take a photo of a problem and get the answer?
Yes: Photomath, Google Lens, Scholarly, Mathway, and Brainly all accept photos or uploads. Scholarly adds flashcards and practice from the same input.
What's a free Chegg alternative?
Google Lens homework help is the closest free option for general homework, and Mathway gives free step-by-step math solutions without signing up. Scholarly's free account lets you try the explain-then-practice workflow on your own material. None of these replaces Chegg's textbook solutions library one for one.
How is Scholarly different from ChatGPT for homework?
ChatGPT is a general assistant; Scholarly is a study workspace. Both explain; Scholarly can also turn the same material into flashcards on a review schedule, a practice test, or a short video lecture so you remember it on exam day.
