Quiz AI is a competent homework scanner. Point a phone at a math problem or a paragraph from a textbook, and it spits out a step-by-step solution. The catch is the free plan throttles scans, watermarks exports, and reserves the “scan study materials” feature for the paid tier. Once a student hits a busy revision week, the upgrade prompt becomes a wall. If you’re shopping for a replacement, these 7 Quiz AI alternatives cover the same scan-to-solve workflow with looser limits, broader subjects, or a better step explanation engine.
We picked tools that work on Android phones at low spec, since most students reach for whatever device is in hand during homework.

Why people leave Quiz AI
Common complaints on Reddit r/studytips and on TikTok study creators through 2026:
- The scan cap arrives fast. Free Quiz AI scans run out quickly during a real homework session, and the app puts the upgrade prompt directly over the result.
- Watermarks on exports. The free PDF and Word exports stamp the page, so students who want a clean study sheet either upgrade or screenshot manually.
- Step explanations are shallow. The solver returns answers and a step list, but several reviewers note the steps don’t explain why a move is made, which is the part students actually want.
- Subject breadth is uneven. Math is strong. Chemistry and physics are passable. History or English questions get generic AI prose that doesn’t help.
- Privacy concerns. The app uploads scanned content to its servers and the privacy policy reserves rights to use anonymized scans for training. Some teachers and parents push students off the app for that reason.
Which app should you choose?
-
Photomath if math is the main subject you scan. The most accurate handwriting OCR on the list.
-
Socratic by Google if homework spans more than math. Backed by Google AI, fully free, covers humanities.
-
Mathway if you need a deep math solver across many topics. Wider math coverage than Photomath.
-
Symbolab if you study calculus or higher math. The symbolic engine is the best on the list.
-
Microsoft Math Solver if you want unlimited free steps with no ads. The cleanest free option.
-
Brainly if a worked human answer beats a generated one. Community library with AI fallback.
-
Gauth if you want a tutor chat that walks you through the steps. Closest to “ask a teacher” on the list.
Stay on Quiz AI if you’ve paid for premium and you use the study-materials scan feature regularly. That part is genuinely useful and doesn’t have a clean free equivalent.
1. Photomath -- best for math scan-to-solve
Photomath built the category Quiz AI now competes in. Scan a problem, get the answer, then tap through the steps. The OCR handles handwriting and print roughly equally well, and the step layout is the cleanest on the list. Coverage runs from arithmetic through calculus and basic statistics.
Quiz AI vs Photomath: Photomath is narrower than Quiz AI by design but deeper on the math. Step explanations are clearer, animated tutorials walk through the reasoning, and the free scanner has no monthly cap. Photomath Plus paywalls the full animated tutorials, which mirrors Quiz AI’s paid tier.
Advantages:
- Best math OCR on the list, including handwritten
- Animated step-by-step tutorials
- Free scanning with no monthly cap
- Strong coverage from arithmetic to calculus
Disadvantages:
- Math only, no humanities or science Q&A

- Word problems sometimes need rephrasing
Pricing: Free for the scanner and basic steps. Photomath Plus runs around $9.99/month or $69.99/year for animated tutorials and textbook walkthroughs.
2. Socratic by Google -- best for all-subject homework
Socratic by Google is the closest free, broad-subject match for Quiz AI. Snap a photo of a question or speak it aloud, and Socratic returns explainers pulled from teacher-vetted sources plus YouTube. Subjects cover math, science, literature, US history, social studies, economics, and more. It’s the rare homework tool from a major platform that has no paywall.
Quiz AI vs Socratic: Quiz AI leads on scan UX and prettier output. Socratic leads on subject breadth, source quality, and being entirely free. For a student who switches subjects every period, Socratic is the lighter install.
Advantages:
- Free with no scan caps
- Broad subject coverage beyond math
- Pulls from teacher-vetted sources
- Voice question support
Disadvantages:
- Updates are infrequent, the app feels static
- Math step quality below Photomath
- No export or session history
Pricing: Fully free, no in-app purchases.
3. Mathway -- best for broad math coverage
Mathway covers more math than almost anything on the list. Arithmetic, algebra, geometry, trigonometry, precalculus, calculus, statistics, finite math, linear algebra, chemistry, and physics each get their own solver tuned to that field. You can scan, type, or upload. The free tier shows the final answer; full steps sit behind a subscription.
Quiz AI vs Mathway: Quiz AI is a general homework app that does math acceptably. Mathway is a math app that does math seriously. For a student who is taking precalculus or statistics, Mathway’s subject-specific engines return cleaner, more correct work.
Advantages:
- Widest math topic coverage on the list
- Subject-specific solvers
- Strong chemistry and physics support
- Reliable typed-input fallback
Disadvantages:
- Step-by-step locked behind paid tier
- Subscription is pricier than Photomath

Pricing: Free for answers only. Mathway subscription runs around $19.99/month or $79.99/year for steps.
4. Symbolab -- best for advanced math depth
Symbolab is the calculator math majors keep open. Beyond a normal step-by-step solver, it handles definite and indefinite integrals, derivatives, limits, series, matrix operations, and ordinary differential equations, with graphs alongside the working. The AI Photo Solver lets you scan a problem and choose which method to apply.
Quiz AI vs Symbolab: Quiz AI is for homework. Symbolab is for understanding the math itself. Calculus and linear algebra students get far more from Symbolab’s symbolic engine than from any general scanner.
Advantages:
- Deepest symbolic engine outside Wolfram
- Strong graphing built into the solution view
- Practice problems with adaptive hints
- Covers ODEs, series, matrix algebra
Disadvantages:
- Free tier limits steps per day
- Less intuitive for younger students
- Interface is dense on phone
Pricing: Free with daily step limits. Symbolab Pro is around $9.99/month or $39.99/year.
5. Microsoft Math Solver -- best for unlimited free steps
Microsoft Math Solver is the free option most students underrate. You scan, write, or type a problem and get the answer with full steps, similar problems, and short concept videos. No paywall, no ads, no per-month limit. Coverage runs from arithmetic through quadratic equations, trigonometry, calculus, and basic statistics.
Quiz AI vs Microsoft Math Solver: Quiz AI gates exports and limits scans. Microsoft Math Solver has none of that. For free use, it is a strict upgrade on Quiz AI’s math feature, with concept videos linked from each step rather than gated behind a tier.
Advantages:
- Free with no ads or in-app purchases
- Unlimited scans and step counts
- Linked concept videos for each step
- Graphs algebraic, trig, and parametric expressions
Disadvantages:
- Math only, no humanities Q&A
- No history of solved problems by default
- Microsoft account sign-in for cloud sync
Pricing: Free. No paid tier.
6. Brainly -- best for worked Q&A from peers
Brainly is a community-first homework app with a large library of student-asked questions and verified answers. The mobile app scans a question, finds the most relevant past Q&A, and now layers an AI generator on top when no good match exists. Subjects cover most school topics from elementary through college prep.
Quiz AI vs Brainly: Quiz AI gives a single generated answer. Brainly gives several worked answers from other students, sometimes with the original explanation that helped them. For students who learn by reading another person’s reasoning, the Brainly format clicks faster.
Advantages:
- Huge library of student-vetted answers
- AI fallback when no library match exists
- Most school subjects covered
- Active moderator quality control
Disadvantages:
- Free tier limits answer views per day
- Some library answers are old or low quality
- Verification labels are not always reliable
Pricing: Free with daily answer caps. Brainly Plus is around $24/year for unlimited verified answers.
7. Gauth -- best for AI tutor chat
Gauth (formerly Gauthmath) treats homework as a conversation. Scan a question, then keep the chat open to ask follow-up questions about each step. Subjects include math, physics, chemistry, biology, and languages. A live human tutor option exists for paid users when the AI gets stuck.
Quiz AI vs Gauth: Quiz AI gives one answer per scan. Gauth lets a student push back on the answer and ask for a clearer explanation. For students who treat homework as study time rather than copy time, the chat loop is more useful.
Advantages:
- AI chat that handles follow-up questions
- Live human tutor escalation on paid plan
- Daily free question tickets
- Broad subject coverage
Disadvantages:
- Daily free tickets run out quickly
- Some answers go too fast for beginners
