Businesses per platform
A focused feature set built for service businesses that need reliable, automated scheduling without the complexity.
Customers book, cancel, and reschedule entirely over text. No app, no login, no friction — just a phone number.
When a customer calls and hangs up, Zentaris automatically texts them back with a booking menu within seconds.
Customers type naturally — "tomorrow at 2pm" or "any Friday morning" — and the AI finds the right slot and confirms it.
Appointments book directly into your calendar in real time. Cancellations automatically remove the event — always in sync.
Each business gets their own number, calendar, availability hours, and customer list. One platform, unlimited businesses.
Built-in legal disclaimer on first contact, STOP/START handling, and full A2P 10DLC compliance support — ready out of the box.
The AI remembers context mid-conversation — customers can say "yes" to confirm or "cancel and rebook" in a single message.
No code, no integrations to build. Connect your Google Calendar, set your hours, and start accepting bookings in minutes.
Zentaris is designed to disappear into the background — it just works, so you can focus on your customers.
Link your Google Calendar, set your working hours, and configure your business phone number. Done in under 5 minutes.
Share your Zentaris number. Customers text naturally — the AI interprets their request and offers available slots instantly.
Once confirmed, the appointment lands on your Google Calendar. Reminders go out automatically. Cancellations clean themselves up.
