Google Calendar is the scheduling tool used by individuals and teams to manage appointments, meetings, and availability. It supports multiple calendars, free/busy availability, calendar invites and reminders, business hours and buffer times, and shared team and room calendars. It exposes an API for real-time free/busy queries and event creation, which is what makes a real-time AI voice integration possible rather than theoretical. ## What does the Google Calendar integration do? When the AI handles a call, it: - **Checks availability in real time** - the AI checks your Google Calendar during the call and offers only genuinely available time slots. No more "let me check and call you back". - **Books instantly** - when the caller picks a time, the AI creates the event immediately. The appointment appears in your calendar before the call ends. - **Sends a calendar invite to the caller** - the caller receives a Google Calendar invite with date, time, location, and any pre-visit instructions, which reduces no-shows by keeping the appointment visible. - **Supports multiple calendars** - the AI checks availability across team members or rooms and finds the next available slot for the right doctor, stylist, or consultant. - **Respects buffer time and business hours** - buffer time between appointments, lunch breaks, and business hours are all honored when offering slots. - **Reschedules and cancels by phone** - existing patients or clients can call to reschedule or cancel. The AI finds the event, updates the calendar, and sends updated invites. ## How does Ainora connect to Google Calendar? 1. **Caller requests a time.** The AI asks about preferred date and time, then checks Google Calendar availability in real time during the conversation. 2. **Slot confirmed instantly.** The AI creates the calendar event, adds the caller as a guest, and includes location and prep instructions. 3. **Invite arrives immediately.** Both you and the caller receive Google Calendar invites. Reminders fire automatically before the appointment. Ainora connects to the Google Calendar API and performs real-time free/busy queries. After setup it runs automatically. ## Can the AI handle multiple staff calendars? Yes. You can configure multiple calendars (for example, Dr. Smith, Dr. Jones, Room A). The AI knows which service requires which calendar and checks the right one. It can also find the earliest available slot across all relevant calendars. ## What happens if someone books the same slot while the AI is on a call? Ainora performs a final availability check at the moment of booking. If the slot was taken in the meantime, the AI immediately offers the next available time. This prevents double bookings. --- ## FAQ **How does the AI check calendar availability during a call?** Ainora connects to the Google Calendar API and performs real-time free/busy queries.
