Screen Annotator
Draw straight onto the screen while you explain it.
Draw on your screen during demos, lectures, and walkthroughs. For teachers and presenters.
An interactive demonstration: dragging across this area draws a freehand stroke, matching what Screen Annotator does over any window on your screen.

What it does
Draw over anything
The canvas sits above every window, so you can circle a line of code, an invoice field, or a diagram without switching tools.
Arrows and shapes when freehand won't do
Hold a modifier to snap a straight line, a rectangle, or an arrow instead of drawing it by hand.
Clears in one keystroke
Wipe the screen and carry on talking. Nothing is left behind on the desktop underneath.
Keyboard driven
Colour, thickness, and undo all sit on shortcuts, so you never break eye contact to hunt for a toolbar.
A closer look
- Freehand notes drawn over a running application
