A screen highlighter and annotation tool is a software application designed to enhance live demonstrations, virtual meetings, and lectures by allowing users to draw, highlight, and write directly over any desktop application. Rather than being a single proprietary piece of software, this category includes prominent productivity utilities like Microsoft ZoomIt, Epic Pen Pro, Presentify for Mac, and Ezy Pen. These tools function as a transparent digital layer on top of your operating system, letting you emphasize information without altering the underlying files or presentations. Core Features
Real-Time On-Screen Drawing: Presenters can utilize freehand digital pens, highlighters, and predefined shapes (lines, arrows, rectangles, and ellipses) to mark up active software, documents, or websites.
Cursor and Click Customization: Utilities often feature a “halo cursor” or localized spotlight effect to help audiences track the mouse across high-resolution displays. Visual ripple effects can also display left and right mouse clicks.
Keystroke Display: For software tutorials, some platforms offer an overlay that visually renders keyboard shortcuts (e.g., Ctrl + C) on the screen in real-time.
Screen Magnification and Zooming: Presenters can instantly zoom into complex charts, lines of code, or fine spreadsheet details while keeping the ability to draw on the magnified region.
Integrated Whiteboard Mode: Users can toggle a hotkey to replace the desktop screen with a blank digital canvas for spontaneous brainstorming or sketching diagrams. Primary Use Cases Ezy Pen – Screen Annotation, Draw & Highlight on Screen
