Field notes
ThisBit uses a keyboard shortcut and drag selection to create an interactive viewing window over the desktop. Its masking approach is described as opaque black windows rather than screen capture, leaving the chosen content live for scrolling, clicking, and typing. The page says the blackout extends across every connected display and includes the menu bar and Dock. It supports macOS 13 Ventura or later on both Apple Silicon and Intel Macs.
