DayCommand: AI Calendar

DayCommand understands what you type or say — no forms, no menus, no
tapping through a dozen fields.

"standup every weekday 9am" creates a recurring event on every calendar
you've connected. "move lunch to 3pm" finds it and moves it. "cancel gym
tomorrow" removes it — with an undo. "am I free at 3?" and "find 30 min
for a run" answer questions your calendar app has never been able to.

WHAT MAKES IT DIFFERENT

• On-device, not cloud. Parsing runs entirely on your phone — no message
limits, no monthly quota, no round-trip to a server. It works on a plane.

• One command, every calendar. Connect Apple, Google, and Outlook calendars
at once, and a single command writes to all of them — moves, renames, and
deletes fan out everywhere automatically, so your calendars never drift
out of sync with each other.

• Real mutations, not just creation. Most "smart" calendar apps can only
parse new events. This one moves, renames, resizes, and cancels existing
events by fuzzy-matched title — and answers scheduling questions directly.

• Genuinely private. Your calendar data goes only to the accounts you
connect. Voice dictation runs on-device (Apple CoreML). Nothing about how
the app understands your commands is sent anywhere.

FEATURES

• Natural-language create, move, rename, resize, and cancel — with a
confirm card before anything destructive happens
• Recurring events: daily/weekly/monthly, intervals, ordinal weekdays
("first Monday of the month"), end dates
• Free-time finder: "find 30 min for a run" returns bookable time slots
• 60-day agenda with a week strip, live parse preview as you type
• Voice dictation, fully on-device
• Home Screen widgets
• Siri quick-add
• Conflict detection when two events would overlap
• Time-zone awareness for events created while traveling

DayCommand connects to Apple Calendar (iCloud), Google Calendar, and
Outlook/Microsoft 365 Calendar. Connect one or all three — everything works
the same either way.
