Frequently asked questions
Does it give diagnoses or medical advice?
No. It gives prices, hours and the information you give it. If a patient describes something urgent, it tells them to go to the ER and alerts the doctor.
Does it work with my clinic's scheduling software?
The Answers and Booking plans use Google Calendar. If your clinic books in its own system, we connect it on the Custom plan, which is quoted separately.
What about my patients' data?
The assistant does not ask for health information. If a patient mentions it on their own, it is used only to handle their request and pass it to your clinic. Details in the privacy policy.
Is it a chatbot?
It's an AI assistant that answers your WhatsApp, yes. It isn't a button menu: it understands what people write and answers with your prices and hours. It doesn't make things up, and anything that needs a person goes to you with a summary. Víctor builds it with your information and reviews it with you before turning it on.
What if my customers want to talk to a person?
They can: you and your team. Ars Vigil answers when no one can (10 p.m., Sunday, hands busy) and passes any customer who asks for a person to you, with a summary.
How much does it cost?
From MXN 1,500 a month plus MXN 5,000 setup, on the Answers plan. The Booking + assistant plan, with appointments in your calendar, reminders and the guarantee, is MXN 3,000 a month plus MXN 10,000 setup. Connecting it to your own system is quoted separately. WhatsApp messages and the AI are included. Plus IVA (VAT).
