03Pre-meeting card
Walk in knowing the room
Five minutes before a meeting with people or a link, the menu bar panel leads with Join, who is coming and the agenda from the notes. It can open itself two minutes before, without taking focus.
- Who has accepted, at a glance
- The agenda pulled from the invitation’s notes
- A time-sensitive reminder a minute before, with Join on it
04Conflicts
Double-booked, side by side
Overlaps among the meetings you have accepted are outlined in every view. The chip opens both meetings next to each other, with Decline on each.
Decline one and the clash is gone.

08Agents and Shortcuts
Ready for your agents
An MCP server runs inside the Mac app, on your machine only, behind a token in your Keychain. A cadence command line speaks to it, and Shortcuts, Siri and Focus plug in too.
- Ten tools: next meeting, agenda, inbox, conflicts, free slots, the brief and more
- Reads are always on. Replies from agents stay off until you allow them
- Run a Shortcut when a meeting starts or ends
- A Focus filter switches the calendar set and can hide declined events
- “Hey Siri, join my next meeting in Cadence”

On the desktop and the Lock Screen
Next up, Today and Inbox widgets on Mac and iPhone, a Live Activity with Join in the Dynamic Island, and a daily brief at the hour you choose.
Beyond the meeting
The rest of your day is on it too.
Dentist at ten, a birthday on Friday, a trip in nine days. Cadence keeps them where you already look.
Reminders
Apple Reminders sit beside your events with their due times. Tick one off in the agenda, day or week.
Weather and birthdays
A forecast on each day, and birthdays from your contacts, so a rainy Saturday and a friend’s party show up before you plan around them.
Countdowns
Pin a trip, a launch or a birthday and see the days left in the agenda, the menu bar and a widget.
Editing
Drag an event to a new time, or open it and change the title, repeat, alerts, people and calendar.
