An AI receptionist is only as useful as the calendar it books into. If it can't check real availability and write the appointment back in real time, you're still stuck with a transcript someone has to act on — which is exactly the gap a custom voice AI integration is meant to close. Lexycall connects to three scheduling tools out of the box: Cal.com, Cliniko, and NexHealth. They solve the same basic problem — real-time booking during the call — but they're built for different kinds of businesses.
Cal.com is an open, flexible scheduling tool that isn't tied to any one industry. If your business runs on a general calendar rather than a healthcare-specific practice management system — service businesses, consultations, general appointment-based work — Cal.com is usually the fit. Lexycall checks Cal.com for open slots live on the call and books, reschedules, or cancels directly into it, the same way a person would.
Cliniko is practice management software built specifically for clinics and allied-health practices — physiotherapists, psychologists, and similar providers who need more than a bare calendar: patient records, treatment notes, and scheduling in one place. If you're already running Cliniko, connecting Lexycall to it means the agent is booking into the same system your practice already lives in, not a second calendar you have to keep in sync by hand.
NexHealth is aimed squarely at dental and medical practices, and it's the natural fit for the dental and broader healthcare use cases we build for most often. It handles the specifics that generic scheduling tools don't — provider-specific availability, appointment types, and the patient-record context a front desk actually needs. When Lexycall connects to NexHealth, a booking call isn't just "put something on a calendar" — it's a real scheduling action inside your practice's actual system.
| Your business | Best fit |
|---|---|
| General appointments, consultations, service businesses | Cal.com |
| Clinic or allied-health practice | Cliniko |
| Dental or medical practice | NexHealth |
In practice, the answer is usually already decided by whatever you're running today — the point of connecting Lexycall to it is that you don't have to switch tools to get an AI receptionist that actually books. And if you're running something else entirely — a practice management system or scheduling tool not listed here — that's exactly what custom integrations are for: we connect Lexycall to the calendar you already use, not the other way around.
