Try the AI Voice Agent

Simulate an Inbound Call

Enter a caller name and phone to test the voice agent booking flow. The AI will collect contact info, ask about the issue, and offer an appointment slot.

Script — What the AI Says

Caller: "Hello? I need someone to look at my AC."
AI: "Hi, thanks for calling! I'm the AI receptionist here. Can I get your name?"
Caller: "It's Mike."
AI: "Great, Mike. What's the address for the service?"
Caller: "123 Oak Street, Springfield."
AI: "Got it. And what's the issue with the AC — is it not cooling, making noise, or something else?"
Caller: "It's not cooling at all."
AI: "Alright. We have an opening tomorrow at 2pm — does that work?"
Caller: "Yes, 2pm works."
AI: "Perfect. I've booked you for tomorrow at 2pm at 123 Oak Street. You'll get a text confirmation shortly. Anything else?"
