Write like it's paper

Lots of capability, one thing to learn
Four things to learn. Everything else follows.
Every tool in Cadema comes from one of four ideas, so new capability always turns up somewhere you already know.

Move anything, anywhere
Strokes, text, shapes, images, tables and equations are all objects on the page. Drag, scale, group or restyle any of them the same way.

In the page
Everything a page needs, nothing it doesn't
Ink that keeps up
The line stays under the nib instead of trailing behind it.
Shade and colour
Soft brushes, opacity and per-notebook palettes for real diagrams.
Tables that behave
Insert, resize and merge — then write inside the cells by hand.
Equations, properly
Write it or type it; either way it stays editable.
Mark up anything
Drop a PDF or photo on a page and annotate straight over it.
No signal needed
Every page opens instantly, on the train or in a basement lecture hall.
Open a blank page in about a second.
Phone, tablet or computer. Bring a stylus or a graphics tablet, or just start typing.
