What We Set Out to Improve.

Business

Partnership
Voice AI Product Development

Coretus handled discovery, UX, AI workflows, integrations, testing, deployment, and ongoing improvement.

Goal

What We Built
AI Voice Support & Booking Assistant

A focused AI solution designed around the client's existing workflows, users, and business systems.

What Was Getting in the Way.

The business received a steady flow of calls for service questions, availability, pricing, appointment changes, and basic support. Staff could not always answer every call, especially during busy periods or outside office hours.

The company wanted customers to get a fast, natural response without replacing human staff for sensitive or complex conversations.

Missed Calls
Potential customers sometimes reached voicemail or had to call again.
Repetitive Questions
Staff answered the same scheduling and service questions throughout the day.
Slow Follow-Up
Important call details still had to be written down and entered into internal systems.
