RegionMirror.

RegionMirror

RegionMirror transforms any portion of your macOS screen into a shareable window, solving the persistent problem of unreadable ultrawide monitor screen sharing in video meetings. Instead of cramming your entire 49-inch desktop into a tiny letterbox or constantly restarting shares when switching apps, you simply drag a region, work normally, and share one clean window that your audience can actually read. It's a one-time $19.99 purchase with a free 7-day trial, designed specifically for professionals who present from large displays.

Product Highlights

• Region-to-Window Sharing: Turn any screen area into a standard macOS window that integrates seamlessly with Zoom, Teams, Slack, and Discord — no special plugins or meeting app support required.

• Flexible Workspace Management: Drag windows in and out of your shared region on the fly, resize or move the area mid-presentation, and keep your notes, chat, and email safely off-screen and private.

• Built-in Presenting Toolkit: Annotate with arrows and text, blur sensitive content instantly, switch to a collaborative whiteboard, and preview exactly what your audience sees — all without leaving your share.

• Instant Keyboard Shortcuts: Save default regions for each display and start sharing with a customizable global keystroke, eliminating setup friction before every meeting.

Use Cases

• Developer Demos: Walk through code, terminals, and documentation in one readable frame while your full IDE workspace remains available on the rest of your ultrawide display.

• Sales Presentations: Seamlessly transition between your product interface, slides, and browser research without stopping the share, keeping your prospect notes and CRM private.

• Remote Training: Teach from multiple applications with consistent annotation tools across platforms, using the built-in whiteboard to sketch concepts without ever dropping screen share.

Target Audience

RegionMirror is built for macOS professionals who rely on ultrawide or large monitors and frequently present in video meetings — including developers, sales engineers, technical trainers, consultants, and remote team leads who need readable screen sharing without sacrificing their expansive workspace.
