Callers book appointments by phone — any time, in seconds.
Heavano connects to the calendar you already use, checks real availability while the caller is on the line and books the slot before they hang up. Reminder calls go out automatically with outbound batch calling.
What is AI appointment booking?
AI appointment booking lets a voice agent schedule appointments over the phone. During the call it checks your calendar for open slots, offers them to the caller, books the one they choose and confirms it — and it can find or cancel existing bookings too, without anyone on your team picking up.

What it handles
Live availability
Open slots are checked in your calendar during the call, so the agent never offers a time that’s taken.
Books during the call
The appointment is created while the caller is still on the line, with their name and contact details.
Finds existing bookings
Callers can ask what they have booked and hear it back straight away.
Cancels on request
Cancellations happen in the call, so the slot is freed for someone else immediately.
Reminder calls
Use outbound batch calling to ring patients or customers before their appointments.
Only what you allow
Each action is a permission you switch on per agent, and every action is re-checked before it runs.
Frequently asked questions
Which calendars does Heavano book into?
Google Calendar, Calendly and Cal.com. You connect the account once, then attach it to each agent that should book.
Can the AI reschedule an appointment?
The agent can find a caller’s existing booking, cancel it and book a new slot during the same call.
Can it send appointment reminders?
Yes — with outbound batch calling, an agent can call a list of people before their appointments, within the calling hours you set.
How much does it cost?
On our default model, calls cost £0.050 per minute inbound and £0.065 outbound in the UK ($0.065 / $0.080 in the US, €0.075 / €0.090 in Europe, ₹5.50 / ₹6.90 in India), billed per second with no monthly fee. Your phone carrier, such as Twilio, bills its own call charges.
