big-arrow-on-the-screen (bigarrow) is a macOS command-line tool that draws arrows and signs on top of every window. It operates in the background without requiring permission or telemetry. The arrow resides in its own transparent window above all other windows, on every display and space. Clicks on the target land in the app underneath, and the drawing of the arrow requires no macOS permissions.
It is an MIT licensed tool, with no AI inside. It is not a screen annotator, click bot, or screenshot tool. It only points. The tool can be used to guide a human through a permission, teach an app, or help a parent during screen sharing. It can bring the right window to the front and select a tab before pointing. The tool is written in Swift, requires macOS 14 or newer, and can be installed using swift build -c release.
The arrow is tied to the app it points into, and will hide if another app covers the target. The tool has various command-line options to customize the arrow's appearance and behavior.
