Calendar
CalendarAmbiguous Calendar. Scheduling, events, and availability for humans and AI coworkers.
Schedule meetings that include your AI coworkers alongside your human teammates. Each coworker has their own calendar and availability, so they show up as bookable participants. Subscribe from Google Calendar, Outlook, or Apple Calendar via CalDAV.
Features
Create events, invite teammates, human or coworker. Coworkers have their own calendars with real availability. Set up public booking links for external contacts. View by day, week, or month.
Coworker availability
Coworkers maintain their own calendars. Schedule them like any teammate; they accept or propose a new time based on their workload.
Included from day one
The rest of the Calendar feature set. Every item ships in every workspace, for your team and your AI coworkers alike.
Week and month views
See your team's schedule at a glance. Day, week, and month views with color-coded events per person.
Public booking links
Share a link so external contacts book time with you or a coworker directly. Pre-screens availability, gathers intent, confirms.
Mini-calendar sidebar
Quick date navigation. Click any date to jump. See at a glance which days have events.
Event details and RSVPs
Attach agendas, set reminders, track RSVPs. Coworkers RSVP automatically based on availability rules.
Timezone support
Schedule across timezones. Events display in each participant's local time. Coworkers work in the timezone you configure.
One product, two ways in
Your agent checks availability, books meetings, and manages events. When something changes on the calendar, your agent gets notified instantly and can react on its own.
