Photo Math Solver vs Gauth
Gauth was built for a phone: photograph the page, get the homework answered. Photo Math Solver was built for the browser — drag a box around what is on screen, in any subject, and follow the method one step at a time.
- Gauth is a phone-first homework app, and the camera is the way in.
- This is a browser extension: the problem stays on your screen and the working appears next to it.
- Both cover every school subject rather than mathematics alone.
- The working comes back typeset, one step per line, at a level of detail you change while you read it.
Photo Math Solver is a browser extension for homework that is already on a screen: draw a box around a question and it lays out the method, not only the answer.
Every school subject is in scope, because what it reads is the region you selected — an equation, a labelled diagram, a source extract, a chart in a set of slides.
It lives in a desktop Chromium browser, so it is the tool for coursework you do at a computer rather than on paper.
Which one should you install?
Photo Math Solver is for
- Homework that is already open in a browser tab on a computer.
- Following a named method step by step, with the detail level under your control.
- Notation that is awkward to retype — stacked fractions, matrices, scanned worksheets.
- Keeping the question, the working and the answer box on one screen.
Gauth is for
- Homework on paper, photographed with the phone already in your hand.
- Studying away from a desk, on iOS or Android, wherever you are.
- A single app covering every subject on the timetable at once.
- Asking a follow-up question in a chat and getting a written reply.
Photo Math Solver and Gauth, side by side
Both read a question from an image and explain it, across every school subject. The rows below are where the two products are shaped differently.
| Photo Math Solver | Gauth | |
|---|---|---|
| Where it was built to live | In the browser, over the page you are reading | On a phone, around the camera |
| Explanation depth | Turn the detail up or down on the same problem as you read | One explanation, with follow-up questions in chat |
| How you give it a problem | Drag a box around it on any tab | Photograph it, or upload an image |
| Subjects it covers | Anything on screen — maths, physics, chemistry, biology, history | Every school subject |
| Step-by-step working | Method named, every step shown | Worked explanation for the question asked |
| How the working is rendered | Typeset notation, one step per line, each step in plain language | A written explanation in the app |
| Practice problems | Built from the problem you just solved | Follow-up questions in the same conversation |
| Problems written on paper | Photograph it, open the image in a tab, drag a box | Point the camera at it |
| Phone apps | Desktop browsers | iOS and Android |
| Best for | Understanding whatever is in front of you on a computer | Homework on paper, answered from a phone |
Try it on the problem you have open right now
Free to install, and it works on the tab you already have open. Drag a box around a problem and the working appears beside it.
What is different here
It is already where the homework is
Online coursework is on a screen, not on paper. When the assignment is a browser tab, photographing that tab with a second device is a detour — dragging a box around the question is not.
Depth is a control, not a format
The same problem reads as four lines when you are checking your own answer and as a full walkthrough when you have no idea where to start. You change it while you are reading, rather than asking a follow-up question and waiting for a second answer.
The working is laid out to be read
Typeset notation rather than flattened plain text, one step per line rather than a paragraph, and a sentence saying what each step did. A fraction looks like a fraction, which matters more than it sounds.
Practice comes out of your own problem
You factored this quadratic and got it wrong, so here are three more shaped like it, immediately.
Nothing moves between devices
The question, the working and the box you type your answer into stay on one screen, so nothing is transcribed from a phone back into a form on a laptop.
How it compares with the other solvers
Same format: prices, a feature table, and where the other tool wins.
- vs MathwayPhoto Math Solver is a browser extension that reads a problem straight off the tab you already have open — a PDF, an online assignment, a lecture slide — and explains it a step at a time.
- vs Question.AIPhoto Math Solver is a browser extension that turns anything you select on screen into a worked explanation — the method named, each step on its own line, in plain language.
- vs SymbolabPhoto Math Solver is a browser extension that explains whatever you drag a box around — an equation, a diagram, a chemistry question, a paragraph of history — step by step, in the tab you are already in.
- vs Wolfram|AlphaPhoto Math Solver is a browser extension that answers a problem exactly as it appears on your screen, without any part of it being retyped into an input box.
- vs ChatGPTPhoto Math Solver is a browser extension that explains one selected problem at a time, in the tab where you found it, without anything being pasted anywhere.
