Features

One notebook for the whole of STEM

Every tool you need to think, solve, and study — designed to feel like one calm surface, not a toolbar of forty buttons.

Infinite canvas

Endless, zoomable space for an entire course.

Math notes

LaTeX-quality equations, typed naturally.

Graphs

Plot functions, data, and vectors live.

Code blocks

Run JavaScript; highlight Python and other languages.

Tables

Units, computed columns, conversions.

Drawing

Freehand sketches, snap-to-grid.

Diagrams · coming soon

Automatic rendering is planned; freehand sketches are available.

Chemistry notes

Text, equations, and images; structure rendering is planned.

Image annotation

Mark up board photos and diagrams.

Infinite canvas

Think in space, not in a single column

Spread a derivation across the page, pin the graph next to it, and tuck the lab table underneath. Zoom out to see a whole semester; zoom in to fix one symbol.

Pan, zoom, and group blocks freely
Connect ideas with arrows and links
Collapse a canvas into one clean note

Note

Green's theorem

Relates a line integral around a closed curve to a double integral over the region it encloses.

Equation

∮_C (P dx + Q dy) = ∬_D ∂Q∂x−∂P∂y dA

Math & graphs

Equations and plots that talk to each other

Type math the way you'd say it and watch it typeset instantly. Reference a function in a graph block and tweak parameters to see the curve respond.

Natural-language & LaTeX input
Live function, data & vector plots
Parameter sliders & tracing

Graph

Damped oscillationy = e⁻ᵏᵗ·cos(ωt)

Code & tables

From raw data to result, in one place

Run JavaScript beside your derivation and copy the results into a table or graph. Python and other languages support highlighting and editing.

Python, R, MATLAB & Julia highlighting
Tables with units & computed columns
Export notebooks as JSON from desktop

Python example · highlighting only

import numpy as np
coeffs = np.polyfit(x, y, 2)
print(coeffs)

x	y (obs)	y (fit)
1.0	-1.5	-1.46
2.0	0.1	0.09
3.0	2.5	2.52

Diagrams & chemistry

Draw the things words can't capture

Sketch a circuit, a free-body diagram, or a benzene ring with snap-to-grid help — then annotate a photo of the real apparatus right next to it.

Shape recognition & smart snapping
Chemistry structures & notation
Annotate board photos & lab images
