ScreenAnnotations 1.6.1: a fluid new feel. Controls respond on press, reveal on hover, and glide with springs — plus full Reduce Motion and Reduce Transparency support.
Draw on your screen, build whiteboards, and organize ideas visually.
ScreenAnnotations is a native macOS menu bar app for screen annotation, whiteboarding, presentations, and AI-assisted diagramming. Use it as a transparent overlay on top of any app, or switch to a dedicated whiteboard workspace for diagrams, lessons, demos, notes, and visual explanations.
NEW IN 1.6.1
- toolbar and gallery controls now respond on press and reveal on hover
- tool selection springs into place, and color pickers slide between swatches
- board cards lift on hover, and the toolbar materializes in when a session starts
- full Reduce Motion support: animations become gentle cross-fades
- Reduce Transparency and Increase Contrast make panels solid with a defined edge
DRAW ON YOUR SCREEN
Screen Overlay mode lets you draw directly over your desktop, browser, design tool, IDE, or presentation:

- keyboard shortcuts for fast tool switching
- color, width, stroke, and fill controls
