Capnot

Capnot is a caption-first screen communication tool for Mac. It adds the layer that was missing while you record, share or present, so a muted call, a noisy room or a silent post does not stop you from explaining what is on screen.

Caption puts words in front of your audience without stopping to edit later, Annotation overlays the screen with drawings and shapes, and Pointer turns the cursor into the centre of attention. Every action has a keyboard shortcut, so nothing depends on hunting through menus.
