For maths tutors and teachers

A maths whiteboard your student joins from a link.

You send a link, the student opens it in the browser and writes along with you. Plots, 3D solids, formulas and the call in one tab.

On general whiteboards, maths is an afterthought.

A function plot gets pasted in as a picture, a pyramid is drawn with the mouse, and the call in a second window covers half the board. And the student needs an account.

  • plots pasted as pictures
  • an account for the student
  • the call in another window

I built this board inside Algebra i Spółka for my own tutoring and have taught my students on it for months. Now it becomes a product of its own, because other tutors asked whether they could use it.

From a link to a lesson in three moves

  1. Open a board

    With a teacher account on the free plan, or in the demo, which needs no sign-up.

  2. Send the link

    The student opens it in the browser. Add a password, or a view-only mode for a whole class.

  3. Teach

    Voice and camera in the same tab. You see the student’s cursor with their name.

The tools a plain whiteboard is missing

  • Function plots

    Type sin(2x) or 1/(x-2)+3 and the board draws it with zeros, extremes and asymptotes. Trig plots get π on the axis.

  • Formulas from the keyboard

    Fractions, powers, roots and limits with no LaTeX, with a live preview.

  • Join from a link

    The student opens a link and is on the board. Optional password and a view-only mode.

  • Voice, camera and chat

    Voice and video from one button, in the same tab as the board. Chat for a link or the homework.

  • Named cursors

    You see where the student is pointing, and who is on the board.

  • Solids and shapes

    Eleven 3D solids and eighteen flat shapes. Hidden edges turn dashed on their own; markers for angles and equal sides.

  • A notebook with pages

    Named pages, squared paper in three sizes or plain, layers, light, cream and dark themes.

  • Writing with a stylus

    On a tablet you write with a stylus as in a notebook, on a computer with the mouse. Three pens at hand, each with its own colour and width, and the eraser removes just part of a stroke.

  • Formula sheet and calculator

    The official exam formula sheet at hand, plus ready boards for the Polish grade 8 exam and matura.

    The formula sheet open at solid geometry

What it looks like in a lesson

  • A rational function plot with the plots panel
    Plot with asymptotes
  • A pyramid, cylinder and cone with dashed hidden edges and the volume formula
    3D solids and a formula
  • Triangles with angle, right-angle and equal-side markers, an inscribed circle
    Shapes and markers
  • Dark theme, large grid, sin(2x) with π on the axis
    Dark theme, π axis

What this board does not do

Better to say it now than for you to find out mid-lesson.

  • No mobile app. It runs in the browser, tablets included.
  • No lesson recording.
  • No school system integrations.
  • No AI solving tasks for the student.
  • The interface is in Polish today. German and English versions are planned.

Pilot

I am looking for ten maths tutors.

  • the full plan free for the pilot
  • in return, at least one real lesson on the board
  • and a few lines on what you miss
Join the pilot

A paid plan comes once the board has ten active tutors, not earlier. Payments via HotPay in Poland and Stripe abroad (in preparation). For schools: a data processing agreement.
