Graph Paper

A program or an AI agent can give a person a plot with a link: it sends a JSON plot document to https://graph-paper.io/plot-link, and the answer has the link. It needs no browser, no account and no API key. For AI agents and programs: make a plot with one link · Documentation · /llms.txt

The collaborative math notebook.

Type an equation. Watch it come alive.

Graph Paper is an interactive math notebook that plots what you type, instantly. LaTeX-quality equations, 2D curves, cinematic 3D surfaces, text, and tables, all in one shareable document. No install, no setup.

The immediacy of a calculator. The polish of a publication.

Mandelbrot set fractal in the complex plane

Mandelbrot Set

The classic fractal defined by iterating complex quadratic polynomials.

 A polar rose whose petal count steps as its frequency changes

Polar Roses

A polar rose r = sin(kθ) whose petal count steps as the integer k animates through a discrete set.

 Hyperbolic paraboloid saddle surface

Saddle Surface

A hyperbolic paraboloid — curves up in one direction and down in the other.

Explore. Explain. Share.

Math that looks right

A full LaTeX typesetting engine and your choice of professional math fonts — every equation comes out publication-ready.

It knows what you mean

Type y = sin x or a full parametric surface — Graph Paper picks the plot type, frames the viewport, and chooses the colors. You do the math; it does the chart.
