Free Photo Math Solversnap the problem, get the steps
A photo math solver reads a picture of a math problem and solves it step by step. Snap the problem on a worksheet, in a textbook or on a whiteboard, attach it in the chat, and ask about any step you do not follow.

Tips for a Better Math Solver Photo
A clear photo is most of the work. Five habits make the difference.
Shoot near a window or under a bright lamp, and avoid your own shadow across the page. Glare on glossy paper can hide a minus sign or an exponent.
A full page with twenty exercises makes the AI guess which one you mean. Photograph one problem, or say its number in your message: "solve question 4b".
Hold the phone flat above the page so lines are not slanted, and crop away the margins. Include the instructions line, because "simplify" and "solve" ask for different things.
A fraction cut off at the edge or a diagram missing one label changes the problem. Check the photo before you send it, and add a second photo if the problem continues on the next page.
Neat handwriting usually reads well. Messy digits, a 1 that looks like a 7 or an x that looks like a multiplication sign can be misread. If in doubt, type the problem under the photo too.
Ask the AI to repeat the problem first. Start with "write out the problem you see, then solve it". If the problem it writes out is not the one on your page, correct it before it solves anything.
How to Solve Math From a Photo
Four steps from your camera to a worked solution.
Photograph one problem in good light. JPEG, PNG, GIF and WebP images up to 10 MB work.
Click the paperclip in the box above and add the photo. Attaching needs a free account.
GPT-5.6 Luna, Claude Haiku 4.5 and Grok 4.5 are free and read images. Choose a quick prompt or write your own request.
The AI writes the solution step by step. Ask why a step works, or ask for a similar problem to try yourself.

- • Say your level: middle school, high school or college.
- • Ask for the method your class uses, for example completing the square instead of the formula.
- • Attach up to 5 photos in one message when a problem runs across pages.
- • For long or hard problems, a larger model such as Claude Opus 5 or GPT-6 Astra uses energy but reasons more carefully.
Check the Answer Before You Trust It
A photo math solver has two places to go wrong: reading the photo and doing the math. The AI can misread a smudged digit, and it can also slip in a long calculation. Neither is rare enough to ignore, so treat the answer as a worked example to check, not as a final result.
Three quick checks catch most mistakes. First, compare the problem the AI wrote out with your page. Second, ask it to substitute the answer back into the original equation. Third, send the same photo to a second model, for example free Claude after GPT, and see if the answers match.
The best use of a photo math solver is to learn the method. Cover the solution, look only at the first step, and try the next one yourself. When you get stuck, ask the AI why that step works, not just what comes next. After two or three problems like that, the next one on the worksheet usually goes faster without any help. The AI homework helper works the same way for science, history and languages.
Photomath is a separate app, published by Google, and N33 is not connected to it. If you are looking for a Photomath alternative that runs in the browser and lets you talk through each step with several AI models, N33 is one option. When the problem is easier to type than to photograph, the AI math solver takes typed problems without an account.
Photo Math Questions
What to know before you snap a problem.
Yes. With a free account, GPT-5.6 Luna, Claude Haiku 4.5 and Grok 4.5 read photos at no cost. Larger models use energy: a new account gets 50 and can claim 10 more a day.
Attaching any file on N33 needs an account. You can type a problem without one.
No. Photomath is a different app, made by Google. N33 is a separate AI chat where you can solve a problem from a photo.
Clear handwriting usually works. Messy writing can be misread, so ask the AI to write the problem out first and correct it if needed.
Arithmetic, algebra, geometry, trigonometry, calculus, statistics and word problems. Picture math problems, where the question is a diagram or a graph, work when the image is sharp and fully in frame.
No. The AI can misread the photo or make a calculation slip. Substitute the answer back in or ask a second model to check.
Yes. It reads the text, turns the story into equations and solves them. Make sure the whole question is in the photo, including what it asks you to find.
Yes. Open N33 in your phone browser, tap the paperclip and take or choose a photo. Nothing to install.
JPEG, PNG, GIF and WebP, up to 10 MB each, and up to 5 files per message.
