Classroom whiteboard
A chemistry-aware whiteboard for live tutoring. Marker-style pens, chemistry stamps, a clickable periodic table, text, undo, grid, and fullscreen. Save your work as PNG or PDF.
Whiteboard
Pick a pen color, draw, drop a stamp, or click an element from the periodic table.
Drawing molecules: click a ring (benzene, cyclopentane, pyridine…) in the side panel, then click on the board — drop it near an existing ring's edge and it fuses chemistry-style. Click any atom to relabel it (C → N/O/S/P/etc.). Click any bond to cycle single/double/triple. Drag an atom to reshape. Ctrl+Z undoes the last action.
