Graph Paper introduces a new way to explore and share mathematics, bringing
interactive 2D and 3D graphics, beautifully typeset equations, and a powerful
Compute Engine together in the browser. From a student's first look at a
function to an engineer's next simulation, Graph Paper makes mathematics
something you can see, interact with, and understand. There is nothing to
install and no account to create: it all starts at
[graph-paper.io](https://graph-paper.io/).

Type an equation and it springs to life as an elegant curve. Add a slider and
the curve starts to move. Make it a surface, then turn it in space, look through
it, or paint it in striking watercolor. The equation stays right beside the
picture, set as beautifully as in a fine textbook and ready for your next idea.

The Showcase is the place to begin, with about 90 examples drawn from
mathematics, science, and the patterns of the natural world, from the Mandelbrot
set to a game of Othello you can play. Open one, make it your own, and see where
it takes you.

## A different view. A deeper understanding.

Some shapes reveal themselves only when you can move around them. Turn a Klein
bottle made of glass and follow its surface as it passes through itself. Rotate
a Möbius strip and trace its single side. Explore Boy's surface from angles no
flat image could ever show.

Graph Paper's 3D materials make appearance part of the exploration. Glass,
chrome, ceramic, and pearl give surfaces, parametric curves, and implicit
equations a physical presence, and help build an understanding of shapes that
are hard to grasp from an equation alone.

## Mathematics, drawn by hand.

Mathematics has always been something to look at. With the new Paper
environment, a 3D surface becomes an illustration. Choose watercolor, pencil,
chalk, hatching, or halftone, and the surface takes on ink and the grain of real
paper. Boy's surface in watercolor looks like a plate from a treasured geometry
book, except that you can spin it to any point of view.

For everyone who loves to draw with equations, there is just as much to discover
in 2D: fractals to zoom into, the Droste effect, whirling squares, a Greek wave
frieze. Your imagination and creativity have new tools to play with.

## A picture you can trust.

A beautiful plot matters only if it is a faithful one. Graph Paper shows what a
function really does where it breaks: an open and a closed circle at a jump, an
open circle at a hole, a dashed line at an asymptote.

Implicit equations get the same care. Plot (x − y)²(x + y) = 0 and both lines
appear, including the one where the expression only touches zero, a detail that
is easy to lose. Where a function oscillates faster than the screen can show,
Graph Paper shades the range it covers instead of drawing a line that is not
there.

And it all stays fluid. While you pan and zoom, the GPU keeps the picture
moving. When you stop, Graph Paper brings the finer detail into view.

## Math that looks like math.

Graph Paper gives mathematical notation the care it deserves. Fractions, roots,
integrals, and matrices take their familiar written form as you type. Five
carefully chosen math fonts give a document a character of its own, and tuned
themes and color palettes keep even complex graphics clear.

An on-screen math keyboard and symbol picker put every symbol within easy reach.
And with support for LaTeX, Typst, and MathML, expressions move freely between
Graph Paper and the tools you already use.

## Powerful computation. Graphics that feel alive.

Behind every exploration is the Compute Engine. It compiles each expression the
moment you enter it, into code for the CPU and into shaders for the GPU, so a
plot keeps up as you drag a slider, pan across a curve, or turn a scene. The
most demanding work, from dense regions to implicit surfaces and large
simulations, is spread across your CPU cores.

The Compute Engine does the calculus, too. Take a derivative to explore a rate
of change, evaluate an integral, find the roots of a function, or fit a curve to
a table of data and plot the model right next to the measurements.

## Beyond a single formula.

Some ideas do not fit in one expression. Epsil, a programming language for
scientific computing, is built right in. Write functions with loops and
conditions, then call them from a plot, a color formula, or an action. Describe
a process, and discover the picture it creates.

With Epsil, a simulation is a few lines of readable code. The Showcase includes
Conway's Game of Life, a traffic jam that forms for no reason, heat spreading
across a plate, a swarm of fish, and a game of Othello whose rules are written
in Epsil. The Buddhabrot follows the orbits of 1.2 million sample points, in
parallel, and gathers them into a single intricate image.

## Made to share.

Share a document with a link, or export a plot as a PNG, JPEG, or SVG image at
screen or print resolution. With Pro, invite collaborators to edit with you in
real time, and turn an individual exploration into a shared conversation.

## Availability

Graph Paper is available now at [graph-paper.io](https://graph-paper.io/).
Plotting is free and needs no account. A free account keeps a few documents in a
personal library. Pro adds more storage, collaborator invitations, and revision
history.

Graph Paper is beginning with a gradual rollout through word of mouth, and
everyone is welcome. Start with an equation you think you already know.

## About Graph Paper

Graph Paper is a space to explore and share mathematics, with interactive 2D and
3D graphics, typeset equations, and the Compute Engine. It runs in the browser,
with nothing to install, at [graph-paper.io](https://graph-paper.io/). Graph
Paper is made by [Farfield Studio](https://farfield.studio/).
