Answers Every Call

AI picks up in under a second. Greets callers by your business name and handles their needs naturally using Bland.ai voice engine.

📅

Books Appointments

Checks availability via Google Calendar, confirms details with the caller, and adds it to your schedule automatically.

💬

Takes Messages

Not a voicemail box. The AI asks follow-up questions and texts you a full summary with urgency classification instantly via Twilio SMS.

🔄

Smart Call Transfers

Urgent calls get forwarded to your cell phone. Everything else is handled and summarized. You set the rules for what gets transferred.

🎤

Custom AI Persona

Choose the voice (matt, emma, josh, maya), set the tone, upload your FAQs and services. The AI sounds like your receptionist, not a robot.

📊

Full Call Dashboard

Every call logged with transcripts, duration, and outcomes. Manage messages, appointments, and phone numbers from one place.
