What Businesses Say

Real results from real businesses

24/7 coverage

“The AI handles after-hours calls exactly the way we would, which was our biggest concern going in. Patients often call late at night with urgent questions or to schedule appointments, and previously, those calls would go to voicemail. Now, every call is answered immediately, no matter the time. Patients get the information they need, appointments are booked seamlessly, and no one has to wait until morning. We’ve seen a noticeable increase in patient satisfaction simply because access is always there.”

FAQ

Frequently asked questions

How does an AI receptionist work?

An AI receptionist uses voice AI to answer incoming phone calls, understand what the caller needs, and take action — like checking your calendar for availability and booking appointments. Prisma Voices connects to your phone number via Twilio, uses Vapi for real-time voice processing, and runs on a large language model trained to handle service business conversations.

Can an AI receptionist replace a human receptionist?

For handling inbound calls, booking appointments, answering FAQs, and sending follow-up messages, yes — an AI receptionist can replace or significantly reduce the need for a full-time human receptionist. It handles calls 24/7, never takes breaks, and books appointments in real time. For complex customer escalations, you can configure call transfers to a human.

What is the best AI receptionist for small businesses?

Prisma Voices is built specifically for small service businesses — plumbers, HVAC technicians, dental practices, law firms, and more. It offers a free plan, setup in under 5 minutes, calendar integration with Google Calendar and Cal.com, and WhatsApp follow-ups. Plans start at $0/month.

How much does an AI receptionist cost?

Prisma Voices starts free (50 calls/month). Paid plans start at $49/month for the Starter plan (200 calls), $149/month for Pro (1,000 calls), and $399/month for Business (unlimited calls). There are no setup fees and all paid plans include a 14-day free trial.

Can an AI receptionist book appointments?

Yes. Prisma Voices integrates directly with Google Calendar and Cal.com. During a call, the AI checks your real availability, offers open time slots to the caller, and confirms the booking — all in real time without hallucinating times or dates.
