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.

01 — ANSWER

Every call picked up before the second ring

Your AI receptionist greets callers on your existing number, understands what they need, answers from your business knowledge, and escalates to a human the moment it matters.

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

The whole conversation loop, on one machine.

Speech recognition, the language model, and the voice run together on our inference servers — no round trips between three vendors' clouds. The call flows from your line, through the AiBox, to local AI and back, in real time.

THE HARDWARE STACK

Two boxes. Zero meters.

The reason NuTalk can sell unlimited is that we build the hardware on both ends of the call.

01 · ON YOUR WALL

NuTalk AiBox

A small box that plugs into the phone line you already have. Line in, internet out — your number stays, your carrier stays, and from that moment every call is answered by your AI receptionist.

02 · IN OUR RACKS

AI Inference Call Server

GPU servers we operate in Texas and Monterrey run the whole AI loop locally — speech recognition, the language model, and the voice. No per-token APIs. No per-minute vendors. That's the unlimited part.
