Notchback keeps the last 30 seconds of your Mac screen in a rolling buffer by the notch. When a bug flashes past or something worth keeping happens, press ⌃⌥R and the moment is saved as a clip. Paste it straight into Slack or a bug report, or send six frames and a ready-made prompt to Claude to find the cause. Nothing is uploaded, and the buffer clears on pause, lock and quit. Free keeps 15 seconds; Pro is $9.99 once.
