About

Everything you need to educate

Paper that fits the subject

Graph and isometric alongside ruled, grid, dots and blank. Squared paper for plotting, isometric for drawing in 3D. These are the pages you'd actually hand out, and most whiteboards don't offer them at all.

Think in pages

Documents are made of A4 pages, not an endless canvas, and live in folders you can nest by class and topic. Last term’s worked example is still on page four, in the folder you left it in.

Saved online, nothing to press

Every page saves itself to your account and syncs to your devices. There is no save button to forget and nothing to lose if a tab closes.

Hand out what you drew

Export a single page or the whole document as a PNG or a PDF, and send it to the class straight after the lesson.

For teachers

Prep it once, inspire every time

Build a worked example the way you would on a whiteboard, then keep it. Kallydo is for teachers and tutors who want the lesson to survive the end of the class.

A lesson stays where you put it

Documents are pages, not an endless canvas, kept in folders by class and topic, so last term’s worked example is still on page four where you left it.

Hand out what you just drew

Export a single page or the whole document as PNG or PDF and send it to the class straight after the lesson.

Pick up on any device

Plan on a laptop, teach from a tablet. Everything saves and syncs on its own, so there's no save button to forget.

For students

Study in a way that stimulates

Some problems only make sense once you have written them out. Whether you are at university or learning on your own, Kallydo gives you the space to do that, and keeps every page for when you come back to revise.

Think step by step

Pen, highlighter and eraser with ink that keeps up with you. It feels close to paper, and you never run out.

Nothing to lose

Your pages save themselves. Come back a month later, the night before the exam, and the working is exactly where you left it.

Revise anywhere

Sign in on any device and your notes are there, in the library or at the kitchen table. Export a page as PNG or PDF when you need it offline.
