ZoomIt for Mac

From the creator

Mark Russinovich reveals how he used AI-assisted coding to bring ZoomIt, his essential Sysinternals presentation tool, from Windows to macOS in just two days. He traces ZoomIt's origins, explores its zooming, annotation, screen capture, recording, and demo typing capabilities, and explains how AI translated decades of Windows functionality to the Mac platform. The walkthrough culminates in a live demonstration of Demo Mirror, a new feature that lets presenters share a screen or selected window without leaving PowerPoint Presenter View. Watch to see how agentic coding transformed an ambitious cross-platform port into a working, open-source release.
