7 best AI homework helpers for students
Homework is not one problem. Math needs worked steps, essays need a document, and studying needs recall practice. These seven cover different halves of it.
Write It teamUpdated 7 min read
"Homework helper" covers at least four different jobs. Getting unstuck on a math problem, understanding a concept you missed, memorizing vocabulary, and writing a two-page response are not the same task, and the tools that are good at each are mostly different tools.

1. Write It — for anything you have to write
A large share of homework is not a problem to solve, it is a document to produce — a reading response, a lab write-up, a history essay, a research paper. Write It is built for exactly that half, and it runs inside Google Docs rather than in a separate tab.
Apollo Agent Mode reads your assignment prompt and the document, plans an approach, drafts section by section, and shows you the draft before anything lands. Research Mode finds sources and builds a Works Cited. The Writing Assistant underlines grammar, clarity, and tone as you type. And the auto typer puts text into the document keystroke by keystroke rather than as a paste, which matters more than most students realize — a pasted essay is visible in Google Docs version history.
Key features of Write It
- Apollo Agent Mode. Plans and drafts multi-step written assignments inside the doc, with a review step first.
- Research Mode. Source discovery plus a formatted Works Cited in MLA 9, APA 7, Chicago, or IEEE.
- Writing Assistant. Grammar, clarity, conciseness, tone, and repetition checks while you write.
- Tab completion. Inline next-phrase suggestions so you keep authorship while moving faster.
- AI Humanizer and Detector. Rewrite machine-sounding prose, and see what still reads that way before your teacher does.
- Auto Typer. Variable speed, self-corrected typos, natural pauses.
Pros and cons of Write It
Pros
- The only tool here that works inside the document you submit
- Covers the whole written-assignment workflow, not one slice of it
- Free tier with no card required
- Research and citations included rather than a separate subscription
Cons
- Writing only — no help with math, science problems, or memorization
- Browser only, no mobile app
- Not a tutor: it will not walk you through a concept the way Khanmigo does
- Token-metered, so heavy agent use runs down a free allowance quickly
2. ChatGPT — the general-purpose one
The most capable general model available to students, and useful across every subject. The way you prompt it decides whether it helps or hurts: "solve this" produces an answer you did not learn from, while "I got x = 4 and the answer key says 6, where did I go wrong" produces an actual explanation.
Key features of ChatGPT
- Any subject. Math, science, history, languages, code.
- Conversational follow-up. Ask it to explain the step you did not follow.
- Image input. Photograph a problem or a diagram and ask about it.
- Free tier. With usage limits and a smaller model than paid plans.
Pros and cons of ChatGPT
Pros
- Handles every subject, which nothing else here does
- Excellent explainer when you ask it to explain
Cons
- Will happily just do the assignment, which is the failure mode
- Confidently wrong on some math and factual detail
- No document integration — everything is copy-paste
- Citations it produces are often unverifiable and sometimes invented
3. Khanmigo
Khan Academy built Khanmigo deliberately so that it does not hand over answers. Ask it for the solution and it asks you a question back. That is frustrating when you want to be done, and it is the reason it is the best tool here for actually learning the material.
It is tied to Khan Academy content, which means it can point you at the exact lesson covering what you are stuck on.
Key features of Khanmigo
- Socratic tutoring. Guides you to the answer rather than supplying it.
- Tied to Khan Academy lessons. Links directly to the material covering your gap.
- Teacher and parent visibility. Designed to be used openly rather than hidden.
- Non-profit backing. No incentive to maximize your time on the app.
Pros and cons of Khanmigo
Pros
- The only one here explicitly built so you learn rather than finish
- Strong, well-structured underlying curriculum
Cons
- Deliberately slower than tools that just answer
- Coverage follows Khan Academy’s curriculum, so niche topics fall outside it
- Paid subscription for most individual users
- Little help with long-form writing
4. Photomath — for math specifically
Point your phone at a problem and get the solution broken into steps, with an explanation of each. For algebra through calculus it is the fastest way to find where your own working went wrong.
Key features of Photomath
- Camera input. Scan a handwritten or printed problem.
- Step-by-step solutions. Each step shown and explained, not just the final answer.
- Multiple solving methods. Often shows more than one route to the same answer.
- Works offline for many problem types. Useful without a connection.
Pros and cons of Photomath
Pros
- Best worked-steps math explanations of anything here
- Camera input is genuinely faster than typing an equation
Cons
- Math only
- Easy to use as an answer machine and learn nothing
- Word problems and proofs are much weaker than computation
- Detailed explanations sit behind the paid tier
5. Socratic by Google — free and underrated
Free from Google, aimed at high schoolers, and built to point you at explanations rather than answers. Photograph a question and it surfaces relevant explainers, videos, and step-by-step guides across math, science, and the humanities.
Pros and cons of Socratic
Pros
- Completely free
- Covers more subjects than the math-only tools
Cons
- Less actively developed than the newer AI tools
- Mobile-focused, weaker on desktop
- Quality varies by subject
- No help with producing written work
6. Quizlet — for the memorization half
A lot of homework is not conceptual at all — it is vocabulary, dates, formulas, and terms. Quizlet is built for that, with flashcards, practice tests, and spaced repetition, plus an enormous library of sets other students already made.
Pros and cons of Quizlet
Pros
- Spaced repetition genuinely works for recall
- Huge library of existing sets for common courses
Cons
- Only useful for memorization
- User-made sets contain errors — verify before trusting one
- Some study modes are paid
- No help with understanding, only with remembering
7. Brainly — community answers, with caveats
Brainly is a question-and-answer community where students post homework problems and others answer. Sometimes you find a clear explanation of exactly your problem. Sometimes you find a confidently wrong answer with no working.
Pros and cons of Brainly
Pros
- Sometimes has your exact textbook problem already explained
- Free to browse
Cons
- Answer quality is inconsistent and unverified
- Strong pull toward copying rather than learning
- Many schools treat posting assignment questions as a policy violation
- Ad-heavy without a subscription
How to use any of these without wasting the year
Try the problem first, badly
Even five minutes of a wrong attempt changes what you get from an explanation. You now have a specific confusion instead of a blank.
Ask why, not what
"Where did my working go wrong" teaches you something. "What is the answer" does not.
Close the tool and redo it
If you cannot reproduce the solution without help, you have not learned it — and the exam is not open-tab.
Check your school’s policy
Some of these are explicitly allowed, some explicitly are not, and the difference is usually written in your syllabus.
For the homework that is a document
Install Write It free — drafting, research, citations, and grammar inside Google Docs.
Frequently asked questions
What is the best free AI homework helper?
Socratic by Google is completely free and covers several subjects. Photomath’s free tier handles most math problems, and Write It, ChatGPT, and Quizlet all have real free tiers. Which is best depends entirely on the subject.
Is using an AI homework helper cheating?
It depends on your school’s policy and the assignment. Using one to understand a concept is usually fine; submitting generated work as your own is prohibited essentially everywhere. Your syllabus is the authority — check it before you rely on any of these.
Which AI homework helper is best for essays?
Write It, because written assignments end up in a document and it is the only one here that works inside Google Docs — drafting, citing, and checking grammar in place rather than in a separate tab.
Is there a free version?
Yes. A free account gets 5,000 tokens once at signup, plus one run of Write It Max and a first Apollo conversation on us. There is no card required to start.
Will this get past an AI detector?
No tool can promise a particular detector score, and we do not make that promise. The humanizer rewrites AI-flavored phrasing so it reads naturally to a person; the AI Detector shows you what still reads as machine-written so you can decide what to do about it.
