Best AI Homework Helpers in 2026: 8 Apps That Explain, Not Just Answer

Updated October 16, 2026 – Tested Intelligence

The best homework app is not the one that finishes the worksheet fastest – it is the one that leaves the student able to do the next problem alone. Judged on that standard, Khanmigo is the standout because it is designed to refuse the shortcut: it tutors with questions instead of handing over answers. Photomath and Microsoft Math Solver are the best free math options, and Socratic by Google covers every subject at no cost.

Khanmigo

Khanmigo is Khan Academy’s AI tutor, and its defining choice is pedagogical: ask it for an answer and it responds with hints and questions that walk the student there themselves, tied to the Khan Academy lesson in progress. It covers math, science, humanities, coding, and writing coaching; a parent account can enable up to 10 child accounts, review conversation history, and get moderation alerts. Learner and parent access costs $4 a month or $44 a year; verified K-12 teachers use Khanmigo’s teacher tools free. There is no free student tier – the trade-off for a tutor built by a nonprofit to teach rather than to complete.

Best for: Families and students who want the learning, not just the completed homework.

Photomath

Photomath (owned by Google) does one subject well: point the camera at a math problem – printed or handwritten – and get a step-by-step solution, not just a result. The free tier includes unlimited step-by-step solutions for standard problem types, which covers most homework. Photomath Plus, at $9.99 a month or $69.99 a year, adds animated tutorials, “how and why” explanations, and solutions matched to specific textbooks. Math only, arithmetic through calculus.

Best for: Math homework where seeing each step is the point.

Socratic by Google

Socratic is the free all-rounder. Snap a photo of a question, or ask by voice or text, and it identifies the underlying concept and returns a plain-language explanation, step-by-step breakdowns where they apply, and curated videos and resources. It spans math, science, literature, history, and more, with no subscription of any kind. The trade-off: it leans on curated resources rather than a conversational tutor, so follow-up questions are limited compared with Khanmigo or Gauth.

Best for: Students who need a quick, free explanation of one stuck question in any subject.

Microsoft Math Solver

Microsoft’s Math Solver is, in its own words, 100% free – every feature, including the step-by-step explanations rivals put behind subscriptions. Enter a problem by scanning it, writing it on the on-screen whiteboard, or typing it into the calculator, and you get solution steps, an interactive graph, similar problems, and video lectures. Daily quizzes and practice games let you prepare, not just check. Coverage runs from arithmetic to algebra, basic calculus, and statistics, on web and mobile.

Best for: Free math help with built-in practice – the best no-cost alternative to Photomath.

Gauth

Gauth is the speed merchant of this list: photograph a question in almost any subject and get a worked solution in seconds, with follow-ups handled by its AI chat. The free tier allows a limited number of solves a day (Gauth does not publish the exact figure; review coverage puts it at roughly 11 questions). Gauth Plus, at $11.99 a month or $99.99 a year, removes the limits, adds step-by-step solutions across subjects, and includes 24/7 access to live human tutors – the feature to use when the AI’s explanation does not land. Because Gauth will simply solve, it teaches only if the student reads the steps; parents may prefer it as a checking tool after work is attempted.

Best for: Older students who want fast worked solutions across many subjects, with human backup on the paid plan.

Quizlet

Quizlet starts from the student’s own material. Its AI features sit inside Quizlet Plus ($35.99 a year, about $2.99 a month billed annually, or $7.99 month-to-month; Plus Unlimited is $44.99 a year): Q-Chat is a Socratic-style tutor that quizzes with guiding questions, and Magic Notes turns pasted text, uploaded PDFs, or class notes into flashcards, summaries, and practice tests. The free tier still covers flashcard creation and limited rounds of the Learn and Test modes.

Best for: Exam preparation and turning class notes into study material you actually rehearse.

Brainly

Brainly is the crowd option: a huge Q&A community where students post questions and get answers from peers, moderators, and AI, with expert-verified and textbook answers mixed in. Asking and reading with ads is free. Brainly Plus, at $10 a month or $39 a year, removes ads and unlocks unlimited verified answers plus step-by-step math solutions; a separate Tutor plan adds live one-on-one chat help. The caveat: anyone can answer, so quality varies – weight “verified” answers more, and cross-check anything high-stakes.

Best for: A quick explanation or second opinion on any subject, at any hour.

Answer AI

Answer AI is a generalist solver app in the Gauth mold: snap or type a question across math, science, and humanities and get an answer with step-by-step reasoning, plus a writing assistant in the same app. The free tier allows a limited number of questions a day; premium removes the caps at about $9.99 a month, or $8.33 a month billed annually (pricing is set in the app stores and varies by region). It lacks Khanmigo’s guardrails and Photomath’s math depth, but covers homework and writing help in one free-to-start app.

Best for: Students who want one app for both problem solving and writing assistance.

How to use these apps without cheating yourself

Every app here can be used two ways: attempt the problem first and use the app to check and explain – which builds skill – or copy the output without reading it, which builds nothing and, if submitted, crosses most schools’ integrity lines. The explaining apps (Khanmigo by design; Photomath and Math Solver by format) make the first way easy. The rule that works: never copy an answer you could not reproduce on a test.

FAQ

What is the best completely free homework app?

Socratic by Google for all subjects, and Microsoft Math Solver for math – both are entirely free, including step-by-step explanations.

Which homework app will not just give my child the answer?

Khanmigo. It is built to tutor with questions and hints, and parents can review the full conversation history afterward.

Is Photomath worth paying for?

Only if the animated tutorials or your specific textbook’s solution library matters to you. The free tier’s step-by-step solutions cover most students’ needs.

Are these apps allowed in school?

Policies differ by school and teacher. Using an app to study and check your own work is widely accepted; submitting app output as your own work, or using one during a test, is not.

Bottom line

Install Khanmigo if the goal is learning with a safety net, Photomath or Microsoft Math Solver for math, and Socratic for free help on everything else. Reach for Gauth or Brainly when you are stuck at midnight and need a worked example fast – then close the app and redo the problem yourself.
