WHAT YOUR AGENT DOES
One agent. The whole front desk.
Not a phone tree. Not a voicemail. A trained AI receptionist that resolves the call — and leaves a record your team can act on.
02 — BOOK
Appointments land on your calendar, not your inbox
Connected to Cal.com, the agent reads real availability, offers times out loud, confirms name, phone, and email — and books during the call.
03 — FOLLOW UP
The conversation continues on WhatsApp
Confirmations, reminders, documents, and reactivation campaigns go out from the same agent, in the same thread, with the full context of the call.
UNDER THE HOOD
From the call to the next step.
Connect your line to the speech recognition, AI model and voice provider configured for your operation. Define calendar actions and when to hand the call to your team.
