Math homework can feel stuck in seconds. One hard problem, one missed step, and the whole evening slows down. A free ai math solver can break that logjam fast. You type or photograph a problem, and the tool shows the answer with the steps that lead to it.
However, “free” means very different things from one tool to the next. Some tools show every step for free, with no account at all. Others, by contrast, show only the final answer and hide the steps behind a paid plan. Still others cap free use after a few questions a day.
So we checked each tool’s own pages in November 2026. For every pick below, you will see the real free limit, the sign-up rules, and the main catch. As a result, you can start with the tool that fits your homework, instead of wasting time on a tool that stops after one problem.

What Is an AI Math Solver, and How Does It Work?
An AI math solver is a tool that reads a math problem and works through it for you. First, you enter the problem by typing it, using a math keyboard, or taking a photo of it. Next, the tool reads the symbols and figures out what kind of problem it is, such as an equation, a derivative, or a word problem. Then it shows the answer, and in the best tools, every step in between.
Most solvers use a mix of two methods. For example, a symbolic engine follows fixed math rules to simplify, factor, or integrate, much like a very smart calculator. A chatbot, in contrast, uses a language model to explain the problem in plain words and to walk through the reasoning. Some tools combine both methods, so you get a correct answer and a clear explanation.
The steps matter more than the answer. If you only copy the final number, you will still be stuck on the next similar problem. When a tool shows each step, however, you can find where you went wrong, learn the rule, and try the next problem on your own. Therefore, this guide ranks free steps above free answers, and it says clearly when a tool hides its steps behind a paywall.
Finally, remember that no solver is perfect. A blurry photo, messy handwriting, or a vague word problem can all lead to a wrong answer. So always check the result against your own rough estimate, and re-enter the problem if the answer looks odd. In short, use the solver as a tutor, not as a shortcut.
1. Photomath: Best Overall
Photomath is the clearest free pick in this guide, because its free plan includes the part that matters most: step-by-step explanations. You point your phone camera at a printed or handwritten problem, or you type it into the smart calculator, and Photomath shows the working. It also handles word problems, and it can show more than one method for some problems.
Free Plan and Limits
Photomath’s own page lists its Basic plan at $0, and it includes step-by-step explanations. There is no daily problem cap stated on that page, and no card is needed for Basic. Photomath Plus costs $9.99 a month or $69.99 a year, and it adds custom visual aids, extra “how” and “why” tips, animated tutorials, and textbook solutions. In addition, the app works on iOS and Android, and its basic features work offline.
Pros
- Step-by-step explanations included free, with no daily cap stated
- Excellent camera scan for printed and handwritten problems
- Shows more than one method for some problems
- Smart calculator and graphs for typed problems
Cons
- Animated tutorials and textbook solutions need Plus
- No full web solver: it is mainly a phone app
- Word problems can be tricky if the wording is vague
2. Cymath: Best No-Sign-Up Solver
Cymath is the fastest way to start. You open the website or app, type a problem or snap a photo, and you get the full solution broken into ordered steps. There is no account to create first, so you can solve your first problem in under a minute. For students who want help right now, that low friction is a real plus.
Free Plan and Limits
The core solver is free and shows full step-by-step solutions, according to Cymath’s own site. No sign-up is required to start, and no card is needed for the free core. The free version shows ads, however, and an optional Plus upgrade removes ads and adds reference material. Cymath covers algebra and calculus, with typed and camera input on web, iOS, and Android. Its Plus price varies by store and region, so check the price in your own app before you pay.
Pros

You can type a problem in math notation, describe it in plain words, or upload a photo. Then its AI chat, called Symbo, lets you ask about any step you do not follow.
Free Plan and Limits
Symbolab’s free tier gives final answers and basic steps, with ads, while advanced steps and fuller explanations need a Pro subscription. Its official App Store listing says basic steps are free and advanced steps need a subscription. Pro prices vary by country and platform, so Symbolab does not list one universal price, and you should check the price at checkout. Pro adds full step-by-step solutions, custom practice quizzes, a cloud notebook, and an ad-free experience. In addition, Symbolab offers practice problems, worksheets, and cheat sheets.
Pros
- Wide topic range, from pre-algebra to calculus and statistics
- Basic steps free, with a math keyboard and photo input
- AI chat lets you ask about a single step
- Practice problems, quizzes, and cheat sheets included
Cons
- Full steps and deeper explanations need Pro
- Free version shows ads
- Pro price varies by store and region, so it is hard to compare
4. ChatGPT: Best for Plain-Word Explanations
ChatGPT is not a dedicated math solver, but it is often the best tool for understanding a problem. You can paste a word problem, upload a photo of your homework, or type a question in plain English, such as “why do I flip the sign here?” Then it explains the idea in simple words, works through an example, and makes a practice problem for you to try.
Free Plan and Limits
OpenAI’s free plan costs $0 and includes unlimited everyday text chats, subject to abuse-prevention safeguards. That means you can ask follow-up questions without counting messages. File uploads are limited to 3 a day on the free plan, however, and image generation, voice, and deep research are also limited. A free account is required, but no card is needed. ChatGPT Plus costs $20 a month and adds a stronger model, faster answers, and much higher limits. In addition, ChatGPT now includes a Study Mode that asks guiding questions instead of giving the answer straight away.
Pros
- Unlimited everyday text chats on the free plan
- Explains ideas in plain words and makes practice problems
- Handles word problems and vague questions well
- Study Mode guides you instead of just giving answers
Cons
- Can make arithmetic or algebra mistakes, so check its working
- Only 3 file uploads a day on the free plan
- No built-in graphing or symbolic math engine
5. Google Gemini: Best Free AI Chatbot
Google Gemini is Google’s free AI chatbot, and it is a strong second chatbot pick after ChatGPT. You sign in with the Google account you already have, then you can type a problem, upload a photo, or ask for a step-by-step explanation. It can also make quizzes, flashcards, and study guides from your topic, which helps when a test is near.
Free Plan and Limits
Gemini is free with a Google account, with no card and no trial. The free plan runs on Google’s lighter Flash-Lite model, and its usage limits are based on compute used, not on a fixed number of messages. Google says those limits refresh every 5 hours, up to a weekly cap, and free users may be limited first when demand is high. The free context window is 32,000 tokens. Paid plans start with Google AI Plus at $4.99 a month, which gives about twice the free limits, and Google AI Pro at $19.99 a month, which gives about four times the free limits and the stronger Pro model.
Pros
- Free with any Google account, no card needed
- Deep Research, quizzes, and flashcards included free
- Upload photos and files to explain a problem
- Works on the web and in the Gemini app
Cons
- Free plan uses the lighter Flash-Lite model only
- Limits are not a fixed message count, so they are hard to predict
- Can make math mistakes, just like other chatbots
6. Gauth: Best for Fast Photo Answers
Gauth, formerly Gauthmath, is a photo-first homework app. You take a photo of a math problem, and it returns step-by-step solutions in seconds. It covers more than 30 subjects, including math, physics, chemistry, and biology, and it also offers live tutor help for questions the AI cannot answer with confidence. For a busy homework session, that speed is hard to beat.
Free Plan and Limits
Gauth is free to download, and its free tier gives a limited number of answers each day. Gauth does not publish the exact daily number, so treat third-party figures with care and check what the app shows you. Gauth Plus removes that cap, adds Gauth AI Pro, and removes ads. On the US App Store, Plus costs $11.99 a month, $31.99 a quarter, or $99.99 a year. A 3-day Plus trial is often offered, but it auto-renews unless you cancel, so set a reminder if you try it.
Pros
- Very fast photo-to-solution answers
- Covers math plus science and other subjects
- Live tutor help for hard questions on paid plans
- Works in more than 50 languages
Cons
- Free daily cap is not published, so it can change without notice
- Plus trial auto-renews if you forget to cancel
- Accuracy drops on advanced or unusual problems
7. Maple Calculator: Best for University Calculus
Maple Calculator is the pick for university-level math. It is powered by the Maple math engine, and it handles algebra, calculus, linear algebra, and differential equations. You can take a photo of a problem, type it with a math editor, or enter it by hand. Then it shows the answer, step-by-step solutions, and 2D and 3D graphs, which help a lot with functions and integrals.
Free Plan and Limits
Maple Calculator is free to download on iOS and Android, with no card needed. The free version gives answers and graphs, plus a small allowance of step-by-step solutions. Maplesoft has said the free version has a limit of 5 steps per week, while the premium version has unlimited steps, although some users report steps that refresh daily. Therefore, treat the free step allowance as small and check the number the app shows you. A premium subscription removes that cap. In addition, the app works offline for many tasks, which suits classrooms and travel.
Pros
- Strong engine for calculus, matrices, and differential equations
- Step-by-step solutions plus 2D and 3D graphs
- Camera, handwriting, and math-editor input
- Works offline for many tasks

8. Khan Academy: Best for Learning Math from Scratch
Khan Academy is different from every other tool in this guide. It is not a solver. Instead, it is a free learning platform with video lessons, practice exercises, quizzes, and unit tests, from early math through calculus, statistics, and linear algebra. If you keep getting stuck on the same topic, Khan Academy helps you rebuild the skill, not just finish tonight’s homework.
Free Plan and Limits
Khan Academy is a nonprofit, and its core lessons, videos, practice exercises, and progress tracking are free, with no subscription and no paywall. You can browse and watch without an account, and a free account saves your progress across devices. The only paid product is Khanmigo, an optional AI tutor, which no lesson or test depends on. As a result, there is no free-trial clock and no card to enter for the main library.
Pros
- Entire core library free, with no paywall or trial
- Structured courses from basic math to calculus
- Practice with instant feedback and progress tracking
- Trusted by schools and used by millions of learners
Cons
- Not a solver: it will not answer a photo of your homework
- Slower than a solver when a deadline is close
- AI tutor Khanmigo costs extra
How to Choose the Right Free AI Math Solver
First, decide what you need most. If you need steps for free, start with Photomath or Cymath, because both show full working without payment. You can solve tonight’s homework and still learn the method.
Next, think about your level. For school algebra and geometry, Photomath and Cymath are enough. For calculus, statistics, or university math, by contrast, Symbolab and Maple Calculator are stronger, even if some of their steps need a paid plan. Khan Academy, meanwhile, is the best choice when the topic itself feels new.
Also, check how you like to enter problems. If your homework is on paper, pick a strong camera tool, such as Photomath, Gauth, or Maple Calculator. If it is a word problem or a “why does this work?” question, however, a chatbot such as ChatGPT or Gemini will explain it better than a symbolic solver.
Finally, watch the limits. Photomath states no daily cap on its free steps, while Gauth caps free answers each day without publishing the number, and Maple Calculator gives only a small weekly step allowance. ChatGPT limits file uploads to 3 a day, and Gemini limits compute, not messages. Therefore, keep two tools ready: one solver for answers and steps, and one chatbot for explanations.
Use Solvers to Learn, Not Just to Copy Answers
A solver can help you learn, or it can quietly hurt your grades. The difference is how you use it. If you copy the answer and move on, you will face the same problem again on a test, with no solver to help. If you study the steps instead, you will start to see the pattern, and the next problem will feel easier.
So try this simple routine. First, attempt the problem on your own for five minutes. Next, use the solver to check your work and find the step where you went wrong. Then cover the answer, redo the problem from scratch, and explain each step out loud in your own words. Finally, try a similar problem without any help. As a result, the solver becomes a tutor, not a crutch.
Also, be honest about school rules. Some teachers allow solvers for checking work, while others treat copied answers as cheating. When in doubt, ask your teacher what is allowed, and use Khan Academy or ChatGPT Study Mode to learn the method instead of copying a final answer.
How to Solve a Math Problem with a Free AI Math Solver
The basic flow is the same in almost every tool above. Follow these steps, and you will end with an answer you understand, not just a number to copy.
- Try the problem first. Spend five minutes on your own. Note where you get stuck, because that step is what you need to learn.
- Pick one tool for the job. Use Photomath or Cymath for steps from a photo, Symbolab or Maple Calculator for advanced math, or ChatGPT or Gemini for a plain-word explanation.
- Enter the problem clearly. Take a clear, straight photo in good light, or type the problem with the math keyboard. Check that every number and sign is correct before you solve.
- Read every step, not just the answer. Next, follow the working line by line. Ask the chatbot or the AI chat what a step means if it is unclear.
- Check the answer yourself. Estimate the result in your head, or test it with a simple number. If the solver’s answer looks far off, re-enter the problem.
- Redo the problem without help. Finally, cover the screen and work through the same problem on paper. If you can do it alone, you have learned it.
Frequently Asked Questions
Is there a truly free ai math solver with no sign-up?
Yes. Cymath is the clearest example in this guide. Its core solver is free, it shows full step-by-step solutions, and you can start without creating an account. Photomath’s free Basic plan also includes step-by-step explanations, although you need the app to use it.
Which free ai math solver is best overall?
Photomath is the best overall pick here. Its Basic plan is free and includes step-by-step explanations from a photo, with no daily cap stated, and it handles word problems and more than one method. If you need advanced calculus help, however, pair it with Symbolab or Maple Calculator.
Can a free ai math solver solve word problems?
Yes, but results vary. Photomath can scan word problems, and ChatGPT and Gemini are often better at reading vague wording and explaining what the problem asks. For best results, type the full problem clearly, with all numbers and units, instead of relying on a blurry photo.
Do free math solvers show step-by-step solutions?
Some do, and some do not. Photomath and Cymath show full steps free. Symbolab shows basic steps free, with fuller steps on Pro. Mathway and WolframAlpha, by contrast, show mainly final answers free and keep full steps on paid plans, which is why they are not in the top eight here.
Is it cheating to use an AI math solver for homework?
It depends on your school’s rules and how you use it. Checking your work, finding a mistake, and learning the steps is normal study help. Copying answers without learning, however, can count as cheating and will hurt you on tests. When in doubt, ask your teacher, and use the solver to learn the method.
What happened to Microsoft Math Solver?
Microsoft retired Microsoft Math Solver on July 7, 2025. The standalone app was removed from app stores, and its website no longer offers a solver. That is why it is not listed as a working tool in this guide, even though older lists still name it. Photomath and Cymath are the closest free replacements for its free step-by-step help.
Final Verdict
For most people, Photomath is the best free ai math solver to start with. It is free, it shows steps, and its camera scan makes homework fast. Then, if you want a no-sign-up web option, keep Cymath ready as a backup, and use ChatGPT or Gemini when you need the idea explained in plain words.
Whichever tool you choose, keep the last step human. Use the solver to find your mistake, redo the problem on your own, and learn the method behind the answer. That mix gives you finished homework and real math skills that last past the next test.
