Calendar
in plain words.
included in
Free, and every plan above it
Every built-in app is fully functional on the Free plan. See pricing.
Calendar is the scheduling app for the desktop: three views of your time, full event creation and editing including multi day spans and repeating series, and reminders that fire through the same notification system every other app uses.
Every one of those actions is also exposed to your agents as calendar tools, so scheduling something can be as simple as asking an agent to do it.
