Calendar meetings, off by default (Settings › Meetings, also offered during onboarding). Notarius watches your Apple Calendar and, ten seconds before a scheduled meeting starts, sends a notification named after the event and holds the record panel ready, pre-filled with that name.
Works alongside or instead of meeting detection – if both are on, a meeting your calendar already announced doesn't get a second banner from the microphone watcher. Only timed events with at least one other attendee count: all-day events, declined invitations and solo blocks stay quiet, and a meeting already five minutes underway when the app starts is not announced after the fact. Recording never starts by itself.
Turning the option on asks macOS once for calendar access; events are read on your Mac only locally. Google Calendar is on the roadmap – visible in Settings, not wired yet.
