Case study

How LIDIA became the receptionist that never sleeps

We designed and developed a conversational AI agent on WhatsApp that books, confirms, charges deposits and reminds patients automatically, with its own website and real-time business reports — now in use at clinics across Argentina, Uruguay, Spain and Chile.

The challenge

Clinics lose patients when nobody answers at night or during peak hours.

Clinics and private practices lose patients every day over something as simple as not responding in time. At night, on weekends or during peak hours, no one answers — and the patient doesn't wait: they book with whoever replies first. Confirming and reminding patients one by one by hand eats up hours, and when nobody does it, no-shows leave the slot empty. And once several professionals are involved, coordinating the schedule by hand ends in overlapping appointments, gaps and double bookings.

Unanswered messages at night, on weekends and during peak hours — the patient books elsewhere

The goal wasn't another chatbot, but a digital receptionist that books, charges and organizes on its own
