Capnot puts captions, annotations and pointer tools on top of any app on your Mac, so a screen demo still makes sense with the sound off. Type a subtitle, or a speech bubble that follows your cursor, or just talk and it captions you live. Draw arrows, boxes and numbered steps, blur anything secret, then spotlight or magnify the part that matters. Every tool is one hotkey away and works with any screen recorder or screen share. No editing afterwards, no subscription.
