24/7 AI Scheduling, no lost patients or empty appointments
Fontumi OneAI automates medical appointment booking via WhatsApp and Calls, confirms attendance, reactivates inactive patients and aligns everything with your calendar in real time. More patients served, less time on the phone.

Manage your operation with a 24/7 assistant
Use your Internal AI Assistant from the Fontumi One app. Look up appointments, schedule, cancel, and block time by chatting.
You talk normally. The AI understands.
No strange commands, no formats. Talk to your internal assistant and the schedule moves on its own.
"What does my schedule look like today?"
→ List of appointments with reason, time, and status.
"Book Juan for Friday at 3 pm"
→ Creates the appointment and notifies the client.
"Cancel Pedro García's appointment"
→ Cancels and notifies via WhatsApp.
"I'm on vacation next week"
→ Blocks the calendar and reschedules affected appointments.
"How many times has María López visited?"
→ Full client history.
"Give me this month's summary"
→ New clients, appointments, comparison.
Your patients book on their own, whenever they need to. Using your WhatsApp number
No waiting. They message "I want an appointment", the AI agent guides them — you don't intervene. → Self-scheduling is optional. If you don't want it, just turn it off.
