Limelight
What is a Markup Tool?
A markup tool lets you add visual marks such as lines, arrows, shapes, or highlights over content to point out details or explain ideas.
A markup tool is software for layering visual notes onto something else. The term overlaps heavily with annotation; markup tends to emphasize quick visual marks like circling a button or drawing an arrow rather than long written notes.
Markup tools range from built-in features, such as macOS Markup for images and PDFs, to live on-screen tools that draw over any app in real time. The built-in kind edits a saved file, while a live tool simply paints on top of the current screen so you can highlight things as you speak.
Limelight provides live markup on macOS. As a menu-bar app it lets you draw freehand over whatever is on screen during a demo, lecture, or call, then clear it with a shortcut. It is a pure overlay, so it runs alongside any recorder or meeting app without changing or saving the underlying content.

FAQ
