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.
