How to take a picture of your homework and get answers
To take a picture of your homework and get answers, you need an AI homework scanner: an app that reads the question from your camera and generates a worked solution. Here's the whole process with Socratic Solve:
- Download Socratic Solve free on the App Store (iPhone and iPad) or Google Play (Android).
- Tap Scan Question and point your camera at the problem: a textbook page, a worksheet, an exam paper, even handwriting.
- Line the question up inside the capture frame and snap. The AI reads it and returns the answer with a full step-by-step explanation.
No retyping x² and √ symbols on a phone keyboard, no scrolling through forum threads about a similar-but-not-your problem.

What happens after you snap the photo
Two things run behind the scenes. First, vision AI reads the image (the printed or handwritten text and the equations) and converts it into a question it can reason about. Then the solver works the problem the way a tutor would and writes out each step: what's given, what's being asked, which rule or formula applies, and how each line follows from the last.
That last part is what separates a real homework helper from a calculator. A bare answer gets you one point; the steps teach you the method the next twenty questions will reuse, and they let you check work you've already done.
What kinds of homework can you photograph?
- Math: arithmetic, algebra, geometry, trigonometry, logarithms, matrices, calculus. See the photo math solver guide.
- Physics: kinematics, forces, tension and friction problems. See the physics guide.
- Chemistry: balancing equations, moles, stoichiometry. See the chemistry guide.
- Biology, history and other subjects: written questions, definitions, cause-and-effect explanations.
- Word problems: the AI reads the full sentence context, not just the numbers.
What photo solvers handle well, and where they struggle
Any photo homework solver is only as good as what it can read. Here's how common question types tend to go:
| Question type | How it usually goes | What to do |
|---|---|---|
| One printed equation or textbook question | Reads reliably | Crop to that question and snap |
| Neat handwriting | Usually reads well | Dark pen, good light, one problem per photo |
| Word problems | Works if every sentence is in the photo | Check that the question doesn't start on the previous line or page |
| Multi-part questions, (a) (b) (c) | Mixed, because later parts build on earlier ones | Scan the shared setup together with the one part you need |
| Questions that rely on a graph, figure or table | Harder, because values have to be read off the picture | Keep the figure in the shot; if its numbers are tiny, type the question with those values written out |
| Faint, messy or crossed-out handwriting | Unreliable | Rewrite it neatly or type it |
| A photo of the whole page | The solver may pick the wrong question | One question per photo, always |
7 tips for a scan that works first time
- One question per photo. Frame a single problem, not the whole page. You'll get a focused answer instead of a summary.
- Fill the frame. Get close enough that the question is large and readable, especially small exponents and subscripts.
- Mind the lighting. Daylight or a desk lamp beats a shadowy bedroom shot; avoid glare on glossy textbook pages.
- Keep it flat. Hold the page (or the phone) so the text isn't warped at an angle, and keep your phone's shadow off the page.
- Include the diagram. If the problem refers to a figure, capture it in the same shot, since it's part of the question.
- Write it out cleanly if it's your own handwriting. Dark pen on plain or lined paper, with space between lines. Make look-alike characters distinct: cross your 7s and Zs, and don't let a 1 turn into a 7 or a 5 into an S.
- Check what was read. A good solution starts by restating what's given. Compare that line against your sheet. If a number, sign or exponent is wrong, retake the photo or type the question before you trust the answer.
A worked example: what a good answer looks like
Say you photograph this word problem from a pre-algebra worksheet:
A phone plan costs $15 a month plus $0.10 for each text message. Last month's bill was $23.40. How many texts were sent?
A useful solution doesn't just print "84". It shows the reasoning, like this:
- Given: fixed cost $15, $0.10 per text, total bill $23.40. Unknown: the number of texts, call it t.
- Set up the equation: 15 + 0.10t = 23.40
- Subtract 15 from both sides: 0.10t = 8.40
- Divide both sides by 0.10: t = 84
- Answer: 84 texts were sent.
Check: 84 × $0.10 = $8.40, and $15 + $8.40 = $23.40, which matches the bill.
Notice that the step worth learning is step 2, turning sentences into an equation. The arithmetic after it is routine. In any solution, find the step you couldn't have written yourself and spend your attention there.
We tested it: a handwritten check from a national math test
To see how a photo solver copes with handwriting, we used a released question from the 2024 NAEP Grade 12 math assessment (the "Nation's Report Card," run by the U.S. Department of Education). It shows a handwritten restaurant check and asks for the subtotal and a 20% tip. We uploaded the image to Socratic Solve 1.2 from the photo library (on an iPhone simulator) on November 9, 2026.
- What it read: all six handwritten prices, from $7.75 for the hamburger to $3.00 for the tea.
- What it answered: it added the prices one at a time (16.25, 23.25, 28.50, 33.00, 36.00) for a subtotal of $36.00, then worked out 0.20 × 36.00 = $7.20 for the tip.
- Our check: both answers are correct. The running total is the useful part: if your own sum came out different, you can see exactly which addition went wrong.

How to use the steps to actually learn
Being able to do the next question without your phone is what shows up on your test. This routine takes a few extra minutes:
- Try it first. Even two minutes of writing down what you know and where you got stuck turns the scan into a way to get unstuck, rather than a way to skip the work.
- Find the line you missed. It's usually one step: a rule you forgot, a sign that flipped, a unit you didn't convert. Read that line until you can say why it's true.
- Close the app and redo it on paper. Start from a blank page, not from the solution. If you can't finish, go back to the steps, then try again.
- Do a sibling problem. The next similar question in your textbook uses the same method. Solve it on your own, then scan it only to check your answer.
How to check an answer before you hand it in
AI-generated solutions are study aids, and like any source they can be wrong. A quick check catches most problems:
- Plug it back in. Put the answer into the original problem, as in the phone bill example. If the two sides don't match, something is off.
- Ask if the size makes sense. A car travelling at 4,000 km/h or a negative length means a slip somewhere.
- Answer the question that was asked. Minutes, not seconds; perimeter, not area; the reason for an event, not just its date.
- Re-read the given line. With any photo solver, a common cause of a wrong answer is a misread number or sign, not bad reasoning.
- For written answers, check your notes. In biology or history, compare the explanation with your textbook or class notes, and write the answer in your own words. Our history homework help guide shows how to structure those answers.

Is there a free app to take a picture of a question and get the answer?
Yes, several apps let you start free, but "free" means different things. Some keep basic answers free and charge for the full steps, some show ads, and many cap how much you can do before asking you to subscribe. Before you rely on one, check what the free version actually includes.
Socratic Solve is free to download on iPhone, iPad and Android and comes with free credits, so you can scan questions and see full step-by-step solutions straight away. An optional auto-renewing subscription adds more, and you can turn it off in your account settings. For a side-by-side look at the other options, see our comparison of the best homework helper apps.
How to find worksheet answers by picture
Worksheets need a slightly different approach than a single textbook problem. (Looking for an answer key instead? See how to find answers to homework worksheets, including why keys found online often don't match your version.)
One question at a time, not the whole sheet
A photo of the full sheet makes the solver guess which question you mean. Photograph one question at a time, and include anything it depends on: the instructions at the top, a shared passage, or a data table that several questions use.
Numbered sub-questions
If question 4 has parts (a) to (d), capture the setup with the part you are stuck on. Once you understand how (a) works, try the rest yourself before scanning again.
Fill-in-the-blank and multiple choice
For fill-in-the-blank, include the whole sentence and any word bank. For multiple choice, keep every option in the frame, A through D, so the explanation can show why the right one fits and the others don't. That reasoning is worth more than the letter.
Check, don't copy
Teachers keep answer keys to themselves for a reason: the worksheet is practice, and your mistakes on it show what to work on before the test. Finish the sheet on your own, then scan only the questions you're unsure about and compare. If you got one wrong, find the step where you went off track. Copying answers just moves the problem to exam day, and it breaks most schools' academic integrity rules.
When to type or upload instead of scanning
The camera isn't always the fastest route. Socratic Solve also lets you type a question or upload an existing photo from your library. Use those when:
- A classmate sent you a picture of the worksheet. Upload it straight from your photos.
- The question is on a screen, like a school laptop or an online assignment. A screenshot uploaded from your library is cleaner than photographing the screen; see how to get answers from a screenshot below.
- The handwriting is hard to read, even for you. Typing removes the guesswork.
How to get answers from a screenshot
If the question is already on a screen, skip the camera. Take a partial screenshot of just the question, crop it, and upload it from your photo library. These shortcuts come from Apple's, Google's and Microsoft's own help pages:
| Device | Screenshot shortcut |
|---|---|
| iPhone with Face ID | Press the side button and volume up together. Screenshots save to Photos. |
| iPhone with a Home button | Press the side button and the Home button together. |
| Android | Press Power and volume down together. A preview appears in the corner. |
| Chromebook | Press Shift + Ctrl + Show windows, then choose a partial screenshot. |
| Mac | Press Shift + Command + 4 and drag around the question. |
| Windows | Press Windows + Shift + S to open Snipping Tool and drag around the question. |
A few things make a screenshot easier for a solver to read:
- One question per screenshot, with its instructions, every answer choice and any graph or table it refers to.
- Zoom in before you capture (Ctrl and + on Windows and Chromebook, Command and + on Mac) so the text stays sharp after cropping.
- Leave out menus, timers and other questions. A full-screen capture makes the solver guess which problem you mean.
On a laptop, Google Lens in Chrome ("Search this tab with Google Lens" in the menu) can search a selected part of the page, and on selected Android phones, Circle to Search works without taking a screenshot at all.
Is taking a picture of your homework cheating?
It depends entirely on how you use it. Copying answers you don't understand is cheating yourself, and against most schools' policies. Using the steps to see why your attempt went wrong, unblock yourself on one hard question, or verify finished work before you turn it in: that's what tutors and worked examples have always been for.
