Limelight

Annotate Google Slides while presenting

Google Slides has no live pen tool, so you cannot mark up a slide as you speak. Limelight lets you draw on top of your slides instantly with a single hotkey.

Presenting Google Slides, you often want to circle a number, underline a takeaway, or sketch an arrow while you talk through a slide. Google Slides has no built-in way to draw on a slide during presentation, so the moment passes unmarked.

Limelight runs from your menu bar and draws on top of Google Slides in present mode. Press ⌃⌥3 to start drawing right over your current slide, mark up what matters, then press ⌃⌥C to clear. Undo a stroke with ⌃⌥Z. Since it is a live overlay, it works the same whether you present in the room or share on a call.

Built for teachers, students, and presenters who use Google Slides on a Mac. Draw on screen is a Pro feature.

FAQ

Does it edit my Google Slides file?
No. Limelight draws a temporary overlay on your screen only. Your Slides file is never touched, and you clear the drawing with ⌃⌥C.
Will it show when I share Slides on a video call?
Yes. The drawing is part of your screen, so any call or recorder sharing your screen will display the annotations.
