OmniDazzle

OmniDazzle is a presentation and screen-capture utility from The Omni Group designed to help users highlight, annotate and zoom into portions of their screen during live presentations or recordings. It lets presenters draw attention to specific areas, fade out the background, magnify details, and add visual pointers — useful for software demonstrations, training videos, and live-screen sharing. The app integrates with macOS and supports direct annotation over any content displayed on screen.
