Comparison
Canvas Math vs Photomath
Photomath is a phone camera that scans printed or handwritten problems and returns steps. Here is the honest head-to-head.
Photomath scans a problem with your phone camera and lists steps; you do not work on the page. Canvas Math is the opposite: you write the problem by hand with a stylus, it recognizes your ink in place, computes the answer with a real symbolic engine, and graphs it live where you wrote it.
This is the engine, running right here.
Not a screenshot of a competitor and not a marketing render — the same plotting engine Canvas Math draws your handwritten math with, live on this page. Every point is computed from the math.
y = x² with a tangent line sweeping the curve — the slope is 2x at every point.
What each one is for
Photomath built its reputation on a single motion: point your phone at a worksheet, and steps appear. For a quick check on a printed exercise that is genuinely fast, and for years it was the easiest way to get unstuck on a homework problem you had already written out on paper.
The camera is also the ceiling. You are reading a result about a photo of your work, not working on the work itself. Edit the problem and you re-shoot it. Want a graph, a tangent line, a slope field, or a surface? That is not what a scan-and-step app is for. The math you typed never becomes something you can move.
Canvas Math keeps you on the page. You write with a stylus the way you would in a notebook, it reads the ink as you pause, a computer-algebra system computes the exact answer and writes it back in your own handwriting, and any result you tap turns into a live graph you can pan, zoom, and animate. The act of working it out by hand stays where the understanding happens.

| Dimension | Canvas Math | Photomath | Canvas Math verdict |
|---|---|---|---|
| How you enter the problem | Write it by hand with a stylus or finger | Photograph it with a phone camera | |
| Handwriting recognition | Reads live ink in place, with a confirm-and-edit gate | OCR on a still photo; re-shoot to change it | |
| How the answer is computed | Computer-algebra engine; answers are exact, AI only explains | Step engine, generally reliable on standard problems | |
| Graphing and visuals | Auto-picks the right graph and draws it on the page | Basic graphs for some problem types | |
| Animated / interactive visuals | Tap to animate Riemann sums, Taylor series, slope fields, 3D | Static results | |
| Step-by-step teaching | Voice that works the problem by hand and narrates | Written, tap-through step lists | |
| Stylus & tablet support | Apple Pencil, S Pen, Surface Pen, or finger, with pressure | Phone camera; no writing surface | |
| Works offline | Native iPad app with on-device AI in progress | Mature, established mobile apps |
Where Photomath wins
If all you want is the steps for a problem already printed in a textbook, pointing a camera at it is faster than picking up a stylus — and Photomath's phone-first app is built for exactly that one-handed, on-the-bus moment. Canvas Math wants a writing surface and a tablet.
Who should use which
Reach for Photomath when you have a printed problem in front of you, a phone in your hand, and you just need to see the steps. Reach for Canvas Math when you want to actually work the problem — write it out, get the exact answer in your own ink, and see it graphed and animated so you understand it, not just copy it.
Common questions
Is Canvas Math a Photomath alternative?
Yes, for handwriting-first work. Instead of photographing a printed problem, you write it by hand on a tablet, it recognizes your ink in place, solves it exactly with a symbolic engine, and graphs the result live. It replaces the camera with a real writing surface.
Can Canvas Math read my handwriting like Photomath reads a photo?
It reads handwriting directly as you write, not from a still photo. You pause and it recognizes the expression on the canvas, shows you what it read so you can correct it, then computes the answer and writes it back in your own ink.
Write it. Solve it. Watch it move.
