Field notes
The product keeps a live transcript labeled “You” and “Other,” then refreshes a maximum-three-bullet summary roughly every 90 seconds and after each answer. Its commands divide the work deliberately: z answers the latest question, x reads the main display only when invoked, and c expands the reasoning. Mac users need a virtual audio device such as BlackHole to hear the other side of a call.
