Occlus

A WhatsApp AI receptionist for dental clinics in Hong Kong.

Occlus answers a dental clinic’s existing WhatsApp number in Cantonese and English, books appointments directly into the clinic’s own schedule, and goes silent the moment a staff member replies from the phone. Patients keep messaging the same number they always have. The clinic changes nothing.

What it does

• Books, reschedules and cancels appointments against real doctor and chair availability.
• Answers opening hours, address, parking, prices and the clinic’s own FAQ.
• Sends appointment reminders 24 hours ahead.
• Replies in Cantonese or English, matching the language the patient wrote in.
• States that it is an automated assistant at the start of every conversation.

What it hands to a human

Occlus is not a clinician and does not try to be. It escalates to clinic staff for anything clinical, dental emergencies, insurance questions, complaints, questions about past treatment, and any procedure the clinic has not put on its bookable list. Suspected emergencies are matched against a fixed keyword list before any AI model sees the message: the patient is given the clinic’s emergency number and told to call, and staff are alerted immediately.

When a staff member replies from the clinic’s WhatsApp app, Occlus stops talking mid-conversation and stays quiet. A human is always able to take over.

How WhatsApp is used

Occlus is a Meta Tech Provider. It runs on the WhatsApp Business Platform (Cloud API) with Coexistence, so a clinic’s existing WhatsApp Business App number keeps working exactly as before while Occlus handles messages alongside staff.

• whatsapp_business_messaging — to receive patient messages sent to the clinic and to reply with booking confirmations, answers and reminders.
• whatsapp_business_management — to connect the clinic’s own WhatsApp Business Account during setup and to manage the message templates used for confirmations and reminders.

Each clinic connects its own WhatsApp Business Account and is billed by Meta on its own payment method. Occlus never messages anyone who has not messaged the clinic first, and sends no marketing or promotional messages.

Privacy

Occlus handles patient personal data on behalf of the clinic, which remains the data user under the Hong Kong Personal Data (Privacy) Ordinance. See the Privacy Policy for what is collected, why, and how a patient exercises their access and correction rights.
