RegionMirror

This tool lets users share a selected region of an ultrawide monitor as a normal macOS window in video calls, solving the problem of unreadable full-screen shares. It targets macOS users who present or collaborate in meetings, such as developers, designers, and product managers, across companies of all sizes. It is delivered as a native macOS app with a free 7-day trial and a $19.99 one-time purchase.
