Handwriting in, live math out
Handwrite and graph math on any tablet.
Write the problem the way you would on paper. Canvas Math reads your handwriting, solves it exactly, and the graph draws itself on — right where you wrote it.
Canvas Math lets you handwrite a math problem with a stylus or finger on any tablet, reads your ink in place, solves it exactly with a symbolic engine, and graphs the result live where you wrote it. Write the function and the curve draws itself on — no equation editor, no typing.
Write the function — watch the curve draw itself.
This is the live engine, running on the page. Write y = x² by hand and the parabola commits to the canvas; tap a result and the tangent sweeps, the area fills, the field flows. Every point is computed from the math — nothing here is an image.
y = x² with a tangent line sweeping the curve — the slope is 2x at every point.
From handwriting to a moving graph, in one place
Most ways to graph math start with typing: you build the expression in a palette or a keyboard, then read a plot. That works, but it pulls you out of the handwriting where the thinking happens, and a typed grapher rarely solves the problem — it just draws what you entered.
Canvas Math keeps the whole loop on one surface. You handwrite the problem, it recognizes your ink and shows you what it read so you can fix it, a computer-algebra engine computes the exact answer and writes it back in your own handwriting, and the result becomes a live graph. Curves draw themselves on, vector fields drift, a surface turns in 3D, and a Riemann sum fills in term by term — all from the math you wrote.
It runs on the tablet you already have. Any stylus works, with real pressure and palm rejection, and so does a finger. When you are done, export to PNG, SVG, PDF, LaTeX, MathML, Markdown, or a runnable Python script.
Handwriting-first vs. typing it in
A check marks where the handwriting-first canvas has the edge over a typed grapher; a dash marks where they are comparable.
| Dimension | Canvas Math | Typed graphers | Canvas Math verdict |
|---|---|---|---|
| Entering the problem | Handwrite it with a stylus or finger | Type expressions or build them in a palette | |
| Getting the answer | Solved exactly by a CAS, written back in your ink | Most graphers plot but don't solve symbolically | |
| Seeing the graph | Right graph chosen automatically, drawn on the page | You choose the plot and read it yourself | |
| Calculus visuals | Animated Riemann sums, tangents, slope fields, 3D | Static plots or slider tricks | |
| Learning the steps | A voice teaches the work by hand on the canvas | No teaching in a pure grapher | |
| Device | Any tablet with any stylus, with pressure and tilt | Keyboard and mouse first |
Who it's for
If you study on a tablet and would rather work problems by hand than type them, Canvas Math is built for you — students through calculus and beyond who want the answer and the graph without leaving the page. If you only need a free pure plotter and are happy typing, a dedicated graphing calculator is fine; Canvas Math earns its place when you want handwriting input, exact solving, and live visuals together.
Common questions
What is the best app to handwrite and graph math?
Canvas Math is built for it: you write the problem by hand on any tablet, it recognizes your handwriting, solves it exactly with a symbolic engine, and graphs the result live where you wrote it — including vector fields, phase portraits, and 3D surfaces that move as you write.
Can I graph a function I wrote by hand?
Yes. Write the function with a stylus or finger and pause; Canvas Math recognizes it, and a tap turns it into a graph drawn right onto the page. It picks the right kind of graph automatically and you can pan, zoom, and animate it.
Do I need an Apple Pencil to handwrite math?
No. Any stylus works — Apple Pencil, S Pen, Surface Pen — and so does a finger, on iPad, Android, or Windows tablets and phones. A stylus with pressure and palm rejection feels best, but it is not required.
Does it solve the math or just graph it?
Both. Unlike a pure graphing calculator, Canvas Math solves equations and integrals exactly with a computer-algebra engine, writes the answer back in your handwriting, and then graphs the result. The AI explains the steps; the numbers come from the engine.
