Press Cmd-R while anything plays on your Mac (a YouTube video, Apple Music, a preset demo) and DOT keeps it: trimmed, filed in a library, with its key, tempo and chords. Drag clips into your DAW, or export the chords as MIDI. DOT records the Mac's own sound through macOS, so there's no BlackHole or Loopback to set up. Free to try, then $49 once. No subscription.
