Prologue Clinic
How Prologue's AI agent handles enquiries, so the team can focus on patients.
The clinic was drowning in repeat WhatsApp questions. Voltade's agent now answers the front of every enquiry and books straight into Plato, cutting staff time on enquiries from three hours a day to thirty minutes.

The challenge
- ~70 WhatsApp conversations a day, every one answered by hand, office hours only.
- The same questions came in over and over. Staff copy-pasted templated replies into WhatsApp all day.
- A third of enquiries landed after hours and sat until 9am the next morning, so leads went cold overnight.
- Every enquiry, qualified or not, fell on a person who had to run it end to end, from first question to booked slot in Plato.
- Booking conversion stayed low.
Before, we were managing a lot of repetitive enquiries and customers asking the same things. Our customer service had to copy the same template from their notes and paste it into WhatsApp.
The solution
What the agent handles
The agent takes the repetitive front of every enquiry and leaves the relationship to the team. It answers the FAQs, qualifies the enquiry, finds the slot, and confirms the details. Staff pick up where it matters, the booking and the personal follow-up. Nobody was replaced; the copy-paste work just stopped landing on a person. And it runs after hours, so a 10pm enquiry gets answered on the spot instead of going cold overnight.
Returning patients don't repeat themselves
The agent greets returning patients by name. No reintroductions, no records to pull up. That used to be staff time. Now it happens before the conversation even starts.
One agent, wired into the existing stack
WhatsApp through Envoy. Bookings into Plato. Contacts synced to HubSpot. It isn't a separate tool bolted on the side. It sits inside the systems the clinic already runs.
Built not to guess
It trusts the verified patient record over anything the model might invent, refuses junk data before it reaches Plato or HubSpot, and escalates to staff instead of faking a booking. The team stays in control.
Built for Singapore, eligible for PSG
Local team, local context, and PSG-eligible on the cost. Hosted in Singapore, deployed in weeks, not months.

Now with automation, we deliver faster, more consistent responses, because the chatbot handles them. And the humans focus on the higher-value, personalised customer service.
How the agent books an appointment
- 01
Recognise the patient
Returning patients are greeted by name. No reintroductions, no records to pull up.
- 02
Read the intent
It works out whether the patient wants to book a new appointment or change an existing one, and routes accordingly.
- 03
Find a slot
It pulls the open slots for the right service and offers the ones that fit.
- 04
Confirm, then book
It confirms the details with the patient, then writes the appointment straight into Plato.
- 05
Sync and remind
The contact syncs to HubSpot, and a nightly job sends a WhatsApp reminder around 24 hours ahead.
- 06
Hand off when needed
If a booking fails, or staff are already on the chat, it escalates to a person instead of guessing.
