The whiteboard’s toolbar gives you what you’d expect from a clinical drawing surface — a pen with adjustable stroke and color, an eraser, text, a handful of shapes, and an arrow tool for connecting things. The aesthetic is intentionally hand-drawn rather than corporate-slide; what you sketch looks like therapy, not a deck.

​
The tool palette

The toolbar runs along the top of the canvas. Left to right, the tools you’ll use most:
  • Selection — click an element to move it, resize it, recolor it, or delete it. Drag a box around several elements to grab them as a group.
  • Pen / freedraw — your main drawing tool. Strokes flow naturally and pick up Apple Pencil pressure if your device supports it.
  • Rectangle, ellipse, diamond, arrow, line — quick geometric shapes for diagrams. Hold Shift while drawing to constrain to perfect squares or circles.
  • Text — click anywhere on the canvas and start typing. The font matches the hand-drawn style of everything else.
  • Eraser — drag across strokes to remove them. The eraser only touches what you cross; it doesn’t erase by area.
  • Laser pointer — a glowing red trail that fades after a second. Use it to point at something on the canvas without leaving a mark. Your client sees the laser too, even though it isn’t permanent ink.

​
Color and stroke

When a tool is active, the side panel shows its options — stroke color, background fill, stroke width, stroke style (solid, dashed, dotted), edge style (sharp or rounded), and roughness (clean line vs. hand-drawn squiggle). The default colors are clinical-clean — deep navy for the main stroke, muted blues, greens, ambers, and reds for highlights. Each background fill is paired so the stroke reads cleanly against it without you tuning contrast by hand.
Sticking to two or three colors keeps a session diagram readable when you export it later. The presets follow the same discipline — every preset uses the same small palette so a board with multiple presets dropped on it still reads coherently.

​
Apple Pencil pressure

If you’re drawing on iPad with an Apple Pencil, your strokes pick up pressure variation — press harder for thicker ink, lighter for thinner. The same is true if you’re drawing on a Wacom or any other pressure-sensitive tablet connected to a Mac or PC. Mouse and finger strokes use a uniform weight — the stroke width you’ve set in the toolbar is what you get from edge to edge of the stroke. Pressure also rides across the two-way connection. If your client is drawing on an iPad with Apple Pencil and you have Two-way ON, their strokes show up on your canvas with pressure preserved.

​
Undo, redo, zoom

Standard keyboard shortcuts work as you’d expect:
  • Cmd+Z / Ctrl+Z — undo
  • Cmd+Shift+Z / Ctrl+Y — redo
  • Cmd+= / Ctrl+= / pinch out — zoom in
  • Cmd+- / Ctrl+- / pinch in — zoom out
  • Cmd+0 / Ctrl+0 — reset zoom
  • Space + drag — pan around the canvas
The canvas itself is large — you can scroll past the visible area in any direction and keep drawing. Presets land in your current viewport, so you can use a different region of the canvas for each diagram and scroll between them.

​
Native viewing (iPhone, Android)

The interactive whiteboard tools are designed for a real keyboard and pointer — a desktop or laptop browser, or an iPad with Apple Pencil. If a client joins from an iPhone or Android, they see the whiteboard as a video stream inside their browser. They can watch what you draw, but the pen / shape / text tools don’t show on their side. For Two-way drawing, your client wants a laptop or iPad.
