The whiteboard that speaks math.
An infinite, collaborative canvas built for one-on-one tutoring. Typeset equations, graph functions, sketch diagrams, and talk it through — all in one room.
No sign-up. A session opens instantly — share the link to invite your student.

Natural handwriting
Pressure-sensitive pen and laser pointer — explain a derivation the way you would on paper.
Graph paper
Toggle a grid background and snap to it for clean coordinate planes and free-body diagrams.
Infinite canvas
