All the math of a lesson on one board
Formulas, function graphs, geometric constructions and solids on one canvas. Open a board and start teaching in seconds — students join by a link or a QR code.
Made for a teacher at the board
Math is its native language
Fractions are typed the way they are written, graphs come straight from a formula, and constructions stay exact while you drag their points.
Your data stays yours
Boards are kept in your browser, and a lesson is encrypted from the teacher to every student: the server only passes sealed messages on.
Tools for any lesson
From the first fraction to solid geometry — everything is already on the toolbar.
An endless canvas
Write, draw and lay out the material of a lesson as you like: the canvas pans and zooms.
Formulas
Type formulas on the keyboard: “/” makes a fraction, “^” a power, and templates are always at hand.
Function graphs
Plot several functions on the same axes and change parameters with a slider — the graph follows at once.
Dynamic geometry
Constructions keep their dependencies, not a picture: drag a vertex and everything else is rebuilt.
Solids
The solids of a geometry textbook, which you can turn to show the side you need.
Pages
Split a lesson into pages, like the sheets of a workbook, with tabs at the bottom of the board.
Classroom widgets
A clock and a timer right on the board: time a task without switching to another window.
Lessons with students
Invite the class to your board: everyone sees what you write at once, and those you allow can write too.

A lesson with students in three steps
- 1
Start a lesson
Open the lesson panel at the right edge of the board and start the lesson.
- 2
Invite the class
Show the QR code or send the link. Students join under their own name, with no sign-up.
- 3
Solve together
Let the students in and decide who only watches, who adds their own work and who may change everything.
