The problem it solves

Booking appointments over the phone usually means someone on your team has to be available to answer, check the calendar, and confirm the details. Missed calls mean missed bookings, and manual scheduling eats into time better spent elsewhere.

Who it fits

Healthcare providers, salons, consultants, and other service businesses that book appointments.

How it works

A customer asks a Vapi voice assistant to check availability for a date
The system checks your calendar and reports back the open time slots
The assistant offers those slots and the customer picks one
The system creates the calendar event with the customer's details
A branded confirmation email is sent automatically
