About Kallydo
Kallydo is an online whiteboard app that gives teachers, tutors and students digital A4 paper in ruled, grid, dots, graph and isometric styles. It saves itself and keeps your lessons in folders, so you can come back to any of them and hand them out.
What Kallydo does
Paper that fits the subject
Choose ruled, grid, dots, graph, isometric or blank paper for each page. Graph paper for plotting, isometric for drawing in 3D. They're the same pages a teacher would hand out.
Documents in folders, made of A4 pages
Each lesson is a document, a stack of A4 pages. Documents live in folders, and folders can sit inside folders, so a class can have a folder per topic. Last term’s worked example is still on page four where it was left.
Saved and synced automatically
Every stroke saves itself to your account and syncs across your devices. There is no save button, and a closed tab loses nothing.
PNG and PDF export
Export a single page or a whole document as a PNG or a PDF. Send the lesson to the class the moment it ends.
Pen, highlighter and eraser
A small set of drawing tools with ink that keeps up with the hand. It is built to feel like writing on paper, not like operating software.
What makes Kallydo different
Pages, not an endless canvas
Miro and Microsoft Whiteboard give you one infinite board to pan around. Kallydo gives you numbered A4 pages, so a lesson has a beginning, an end and a page four you can find again, in a folder you named.
Paper a teacher would actually hand out
General-purpose whiteboards such as Miro are built around sticky notes, diagrams and team-workshop templates. Kallydo is built around the paper types used in lessons, including graph and isometric.
One plan, one price
Miro splits its features across Free, Starter, Business and Enterprise tiers. Kallydo has one plan with every feature: $15 a month, or $144 a year billed yearly.
Made for a lesson, not a meeting
Microsoft Whiteboard is built into Teams and Microsoft 365 meetings. Kallydo is built for one person preparing, teaching and keeping lessons, with no workspace or team to set up first.
Your pages stay yours
Kallydo does not read, sell or share your content, and does not use it to train machine-learning models. There is no advertising and no session recording.

- Private tutors teaching maths and science one-to-one, online or in person
