Questions
Straight questions,honest answers.
If they ask, yes: Lena says she is the clinic’s virtual assistant. She uses the name and tone you choose and hands over to your front desk when a person is needed.
Diagnose, never, and no promises of results either. Prices are up to you: quote a starting price, say it depends on the assessment, or not talk about prices at all.
Today with Google Calendar and Cal.com. Clinicorp and Simples Dental are on our roadmap; if you use another system, talk to us.
We use the official WhatsApp API with coexistence: you keep using the app on your phone and Lena answers on the same number. No unofficial mass messaging.
One click on "Take over" and the AI stops in that conversation. Done? "Hand back to AI". If someone replies from the phone, Lena pauses too.
Lena calls to confirm appointments, recover no-shows and reactivate patients at the times you set. Anyone who asks not to be called is never called again, and you choose whether that also applies to WhatsApp.
Meta charges per message, by category. LenaClin picks the cheapest valid route for each message and shows the cost on your dashboard.
Your clinic is the data controller and LenaClin is the processor, with a data processing agreement, access separated by clinic, and export or deletion of a patient’s data whenever you ask.
It depends on your schedule and on Meta verifying your business. Our team guides you through every step until Lena is live.
