Frequently Asked Questions
How do I draw on my screen on a Mac?
Install SketchMouse from the Mac App Store. Activate the annotation overlay with a global hotkey, then draw shapes, arrows, or freehand strokes directly on your live screen. It works over any app without switching windows.
Can I draw on screen during a Zoom presentation?
Yes. SketchMouse's annotation overlay works during Zoom, Google Meet, Teams, and any screen-sharing application. Remote participants see your drawings in real time on the shared screen.
Does drawing on screen affect the apps underneath?
No. SketchMouse draws on a transparent overlay above your applications. The apps underneath continue running normally. When you deactivate the overlay, your annotations disappear and everything is exactly as you left it.
Can I save my screen annotations?
Yes. SketchMouse can export your annotated screen as PNG or PDF using Apple's native ScreenCaptureKit. This gives you pixel-perfect captures of your annotations for documentation, follow-up emails, or tutorial materials.
Is there a free way to draw on screen on Mac?
macOS doesn't include a built-in screen annotation tool. Preview allows markup on screenshots but not on your live screen. SketchMouse is a one-time purchase — no subscription — and is the most full-featured option for Mac screen annotation.
Can I interact with my apps while annotations are visible?
Yes. SketchMouse's annotation overlay is transparent to clicks when you deactivate drawing mode, so you can annotate a button, deactivate, then click that button — all without clearing your drawings. This makes it ideal for live demos where you need to annotate and interact in sequence.
