The 10 Best AI Tools for Homework Help in 2027
Direct Answer
The best AI tool for homework help in 2027 is Khanmigo, Khan Academy's tutor built on GPT-4o, because it refuses to hand over answers and instead walks students through each step Socratically — the safest pick for parents who want learning, not cheating, at $4/month or free for teachers.
The best value is Socratic by Google, a genuinely free mobile app that reads a photographed problem and pulls step-by-step explanations plus curated web and video resources with no subscription at all. This list is for students, parents, and tutors in 2027 who want real understanding across math, science, writing, and reading — and who care about getting the *method* right, not just a final number.
As AI tutors moved from novelty to standard study tools, the gap widened between apps that teach and apps that simply do the assignment, so we weighted pedagogy heavily. Below are the ten tools that actually help you learn, with honest notes on where each one crosses into academic-integrity gray zones.
How We Ranked the Top 10
We scored every tool against six weighted criteria drawn from hands-on testing across algebra, calculus, chemistry, essay drafting, and reading comprehension, cross-checked against G2 and Capterra review volume, Product Hunt launches, and each vendor's official changelog and model cards.
- Teaching quality (30%) — Does it explain the *why* and build skill, or just dump answers? Step-by-step clarity, Socratic prompting, and correctness were tested on 40 mixed problems.
- Accuracy (25%) — Math and science answer correctness, hallucination rate, and how often it flags uncertainty.
- Subject coverage (15%) — Math, science, writing, history, languages, and reading comprehension breadth.
- Ease of use (10%) — Photo capture, clean UI, and how fast a stuck student gets unstuck.
- Price and value (10%) — Free tier depth, real plan prices, and student discounts.
- Academic-integrity safeguards (10%) — Whether the tool nudges toward learning or quietly enables cheating, plus privacy and data-training opt-outs.
We deliberately rewarded tools that make it *harder* to cheat, because schools in 2027 increasingly run AI-detection and honor-code policies, and a tool that gets you suspended is worth nothing.
1. Khanmigo 🏆 BEST OVERALL
Best for: Students who want to actually learn the material | Pricing: Free for teachers / $4/mo or $44/yr for learners | Platform: web
Khanmigo is Khan Academy's AI tutor, powered by OpenAI's GPT-4o, and it is the rare homework tool engineered *not* to give you the answer. When you ask for a solution it responds with guiding questions, checks your reasoning, and only confirms once you arrive there yourself — the Socratic method baked into software.
It covers Khan Academy's full math, science, and humanities catalog, can tutor essay writing by debating your thesis, and gives teachers a dashboard to spot where a class is stuck. At $4/month (or free for every U.S. Teacher and many districts) it is the cheapest serious tutor on this list, and because it is non-profit-backed, your child's data is not sold.
The trade-off is that impatient students hunting for a quick number will find it frustrating by design.
Pros:
- GPT-4o-powered Socratic tutoring that refuses to spoon-feed answers
- Free for all U.S. Teachers and many school districts
- Tied to Khan Academy's full free course library
- Strong parental and teacher oversight dashboards
Cons:
- Deliberately slow — bad for last-minute answer-grabbing
- Coverage is best inside Khan Academy's own curriculum
Verdict: The single best homework tool of 2027 because it builds skill instead of replacing it.
2. Photomath
Best for: Step-by-step math, from arithmetic to calculus | Pricing: Free / $9.99/mo or $69.99/yr Plus | Platform: mobile (iOS, Android)
Now owned by Google, Photomath is the gold standard for math specifically: point your camera at a printed or handwritten problem and it returns the answer plus a fully worked, step-by-step solution you can expand line by line. It handles arithmetic, fractions, equations, trigonometry, derivatives, and integrals, and the free tier already shows steps for most problems.
The $9.99/month Plus tier adds animated explanations, deeper "why this step" commentary, and textbook-specific solutions. Its handwriting recognition is the most reliable in this category, and because the steps are generated from a math engine rather than pure language model, the accuracy on algebra and calculus is excellent.
The honest caveat: it is so good at producing finished work that it is the app teachers worry about most.
Pros:
- Best-in-class handwriting and printed-math recognition
- Step-by-step worked solutions free on most problems
- Reliable accuracy on algebra, trig, and calculus
- Owned and maintained by Google with frequent updates
Cons:
- Math only — no essays, history, or science theory
- Easy to misuse for straight answer-copying
Verdict: The best dedicated math solver, but use the steps to learn, not to copy.
3. Socratic by Google 💎 BEST VALUE
Best for: Free multi-subject help from a single photo | Pricing: Free | Platform: mobile (iOS, Android)
Socratic is Google's completely free homework helper, and nothing else on this list matches its value. Snap a photo of any question — math, science, literature, or history — and it identifies the concept, then surfaces clear explanations, diagrams, and hand-picked YouTube videos from across the web.
It does not just answer; it teaches the underlying idea, which makes it a legitimate study aid rather than a cheat sheet. Because it is 100% free with no subscription and no ads, it is the obvious starting point for any student on a budget. The limits are real: it leans on curated web resources rather than generating original step-by-step math, so deep calculus work is weaker than Photomath, and Google has not updated it as aggressively as its newer AI products.
Pros:
- Completely free with no paywall or ads
- Multi-subject: math, science, literature, history
- Pulls curated explainer videos and trusted web sources
- Backed by Google with strong privacy defaults
Cons:
- Weaker on advanced step-by-step math than Photomath
- Resource-curation model, not a deep generative tutor
Verdict: The best free homework app of 2027 — start here before paying for anything.
4. ChatGPT (Study Mode)
Best for: Conversational tutoring across every subject | Pricing: Free (GPT-4o mini) / $20/mo Plus | Platform: web, mobile, desktop
OpenAI's ChatGPT added a dedicated Study Mode that, like Khanmigo, withholds final answers and walks you through problems with questions and hints instead. On the free tier you get GPT-4o mini plus limited GPT-4o access; Plus at $20/month unlocks the full GPT-4o and o-series reasoning models that handle multi-step proofs and dense science.
It is the most flexible tutor here — paste an essay for feedback, work through a chemistry equation, or practice a language conversation. Its breadth is unmatched, but it is also a general chatbot, so without Study Mode enabled it will gladly write your whole assignment, and it still hallucinates facts and citations often enough that every answer needs verification.
Pros:
- Study Mode delivers guided, answer-withholding tutoring
- Strongest reasoning on Plus via GPT-4o and o-series models
- Covers every subject including essay feedback and languages
- Free tier is genuinely usable for daily homework
Cons:
- Will write entire assignments if Study Mode is off
- Hallucinates facts and fake citations without verification
Verdict: The most versatile tutor — powerful and honest only if you keep Study Mode on.
5. Brainly
Best for: Crowd-verified answers plus an AI tutor | Pricing: Free (limited) / $24/mo or $96/yr Plus | Platform: web, mobile
Brainly combines a massive community-answered question bank with Ginny, its GPT-powered AI tutor, so you get both human-vetted solutions and instant AI explanations. The free tier gives a few AI answers and community access daily; Brainly Plus at roughly $24/month removes limits, hides ads, and unlocks expert-verified answers and the Test Prep features.
Its strength is breadth — millions of existing Q&As across math, science, history, and English mean common textbook problems are often already solved and rated by other students. The honest weakness: community answers vary in quality and correctness, and the platform's entire model leans toward finding existing answers, which makes it one of the easier tools to use for copying rather than understanding.
Pros:
- Huge community library of already-solved questions
- Ginny AI tutor gives instant GPT-based explanations
- Expert-verified answers on the Plus tier
- Strong coverage of common textbook problems
Cons:
- Community answer quality and accuracy are uneven
- Model encourages answer-lookup over learning
Verdict: A solid hybrid of crowd and AI, but verify community answers before trusting them.
6. Gauth
Best for: Fast photo-to-answer across math and science | Pricing: Free / $11.99/mo Plus | Platform: mobile (iOS, Android)
Gauth, built by ByteDance, is a fast photo-solver that expanded well beyond its math roots into physics, chemistry, biology, and even essay help. Photograph a problem and its AI returns a step-by-step solution within seconds, and a tier of live human tutors is available for tougher questions.
The free version handles a generous number of questions per day; Gauth Plus at $11.99/month removes caps and adds priority human help. It is among the quickest tools tested and its broad subject coverage makes it more flexible than a pure math app. The drawbacks: it is owned by ByteDance, so privacy-conscious users should review its data practices, and like other instant-answer apps it makes copying trivial.
Pros:
- Very fast photo-to-step-by-step across many subjects
- Covers math, physics, chemistry, biology, and writing
- Optional live human tutors for hard problems
- Generous free daily question allowance
Cons:
- ByteDance ownership raises data-privacy questions
- Optimized for instant answers, easy to misuse
Verdict: A fast, broad solver — great for checking work if you review the privacy terms.
7. Symbolab
Best for: Advanced math and step-by-step proofs | Pricing: Free (limited) / $6.99/mo or $29.99/yr | Platform: web, mobile
Symbolab is the math nerd's homework tool, handling everything from basic algebra up through calculus, linear algebra, differential equations, and statistics with detailed, expandable steps. Its symbolic math engine shows the actual algebraic manipulations rather than just a final figure, which makes it genuinely educational for higher-level coursework.
The free version solves problems but limits how many full step-by-step explanations you see; the $6.99/month subscription unlocks unlimited steps, practice problems, and a personal AI Math Solver. For college and AP-level students, its depth on integrals, matrices, and series beats most photo apps.
The catch is that it is math-only with a steeper interface, and the free tier's step gating can feel stingy.
Pros:
- Deepest coverage of college-level math topics
- Shows real symbolic algebra steps, not just answers
- Built-in practice problems and graphing calculator
- Affordable at $6.99/month for unlimited steps
Cons:
- Strictly math — no other subjects
- Free tier gates most step-by-step explanations
Verdict: The best pick for AP and college math that demands worked proofs.
8. Question.AI
Best for: All-in-one scan-and-solve plus AI writing help | Pricing: Free / $13.99/mo Pro | Platform: mobile, web
Question.AI is a fast-growing all-purpose helper that pairs photo solving with a built-in AI chat tutor and an essay-writing assistant. Scan a math, science, or language question and it returns step-by-step results; switch to chat and it works like a general study assistant powered by large language models.
The free tier covers everyday use, and Pro at $13.99/month adds unlimited solves, longer essay support, and faster responses. It is popular for its clean mobile interface and the breadth of doing math, writing, and Q&A in one app. The honest concerns: its essay generator is exactly the feature that draws academic-integrity scrutiny, and as a newer entrant its accuracy on hard STEM problems is less proven than Photomath or Symbolab.
Pros:
- One app for math solving, chat tutoring, and essays
- Clean, fast mobile-first interface
- Useful free tier for everyday homework
- Multi-language support for ESL students
Cons:
- Essay generator invites academic-integrity problems
- Less proven accuracy on advanced STEM than specialists
Verdict: A convenient all-rounder — fine for checking work, risky if used to write essays.
9. Course Hero
Best for: College study documents plus on-demand tutors | Pricing: Free (with uploads) / $39.99/mo or ~$9.95/mo annual | Platform: web, mobile
Course Hero is a college-focused study library combining millions of uploaded course documents, study guides, and practice exams with a 24/7 tutor Q&A service and an AI study tool. You can earn free access by uploading your own notes, or subscribe — the headline price is $39.99/month, dropping to around $9.95/month on an annual plan.
Its real value is in course-specific materials: for many college classes, someone has already shared the study set or solved problem set you need. The AI assistant helps summarize and explain those documents. The serious caveat is that Course Hero sits at the center of academic-integrity debates — many universities explicitly ban using shared course materials, so it can get students in real trouble.
Pros:
- Millions of college-specific study documents and exams
- 24/7 human expert tutor Q&A included
- Free access available by uploading your own notes
- AI summarizer for dense study materials
Cons:
- Many universities prohibit using shared course content
- Full monthly price of $39.99 is steep
Verdict: A deep college resource that you must use within your school's honor code.
10. StudyX
Best for: Multi-model AI study assistant with citations | Pricing: Free (limited) / $11.99/mo Premium | Platform: web, mobile
StudyX is a newer AI study platform that routes questions across multiple underlying models — including GPT and Claude — and adds cited sources to its answers, which sets it apart from black-box solvers. It offers photo solving, a writing assistant, document analysis for uploaded PDFs, and subject coverage spanning STEM, humanities, and languages.
The free tier gives a daily allowance; Premium at $11.99/month unlocks unlimited solves, the strongest models, and longer document uploads. Its citation feature genuinely helps students verify answers rather than trust them blindly, which is a meaningful integrity advantage.
As a young product, though, its reliability is still uneven, and the same writing tools that help can easily be misused.
Pros:
- Routes across multiple models including GPT and Claude
- Provides citations so answers can be verified
- Document analysis for uploaded PDFs and textbooks
- Broad subject coverage across STEM and humanities
Cons:
- Young product with uneven reliability
- Writing assistant is easily misused for assignments
Verdict: A promising, citation-first study tool worth trying free before committing.
Which One Is Right for You?
What to Look For
- Does it teach or just answer? The single most important factor. Tools like Khanmigo and ChatGPT Study Mode withhold answers and build skill; photo-solvers hand over finished work and are easy to misuse. Pick based on whether you want to *learn* or just *check*.
- Accuracy and verification. Every AI hallucinates. Favor tools that show worked steps (Photomath, Symbolab) or cite sources (StudyX, Socratic) so you can check the reasoning instead of trusting a black box.
- Academic-integrity risk. Many schools run AI-detection and ban shared course materials. Using a tool to copy answers or generate essays can mean a failing grade or suspension — read your school's policy before relying on any of these.
- Privacy and data training. Check whether your inputs train the model and whether you can opt out. Non-profit Khanmigo and Google's Socratic have stronger privacy defaults than apps owned by large data-driven companies.
- Subject fit and cost. A math-only specialist beats a generalist for calculus; an all-rounder wins for essays plus science. Match the free tier or plan to the subjects you actually struggle with.
What matters less than the marketing: flashy "instant answer" speed. The fastest tool to a final number is often the worst for your grade and your learning — depth and honesty beat raw speed.
FAQ
Is using AI for homework considered cheating? It depends entirely on how you use it and your school's policy. Using a tool to understand a concept, check your work, or get unstuck is widely accepted. Copying generated answers or submitting AI-written essays usually violates academic-integrity rules and can be detected.
Always check your teacher's or institution's stated policy first.
What is the best free AI tool for homework help? Socratic by Google is the best fully free option — it covers multiple subjects, reads photographed problems, and pulls curated explanations and videos with no subscription. ChatGPT's free tier and the free version of Photomath are strong runners-up.
Which AI tool is best for math homework specifically? Photomath is best for school-level math through calculus thanks to excellent handwriting recognition and free step-by-step solutions. For AP and college math involving proofs, matrices, or differential equations, Symbolab goes deeper.
Can teachers detect AI-generated homework? Often, yes. Schools increasingly use AI-detection software, and teachers spot stylistic and factual tells, especially fabricated citations that chatbots produce. Tools that teach rather than write — like Khanmigo and ChatGPT Study Mode — keep you on the safe side.
Do these tools work for subjects beyond math? Yes. ChatGPT, Brainly, Question.AI, and StudyX cover science, history, literature, and languages, while Socratic spans multiple subjects from a single photo. Photomath and Symbolab remain math-only specialists.
Are paid plans worth it over the free tiers? For most students, the free tiers of Socratic, ChatGPT, and Photomath cover daily needs. Pay only when you consistently hit limits or need a specific feature — like Symbolab's unlimited steps ($6.99/mo) or ChatGPT Plus's stronger reasoning models ($20/mo).
Bottom Line
For 2027, Khanmigo is the best overall AI homework tool at $4/month (free for teachers) because it tutors Socratically and refuses to simply hand over answers, building real skill on top of GPT-4o. The best value is Socratic by Google, which delivers genuinely free, multi-subject, photo-based help with curated explanations and videos.
If you only need math, Photomath ($9.99/mo Plus) and Symbolab ($6.99/mo) are the specialists; for conversational, all-subject tutoring, ChatGPT Study Mode (free or $20/mo Plus) is the most versatile. Whichever you pick, use it to learn and verify — not to copy — and check your school's academic-integrity policy first.
