Why Sully.

Book a demo

Typical AI receptionist.

The voice behind the calls

Not tied to one AI company. We choose the best speech and AI models for each health system and switch when better ones ship.

Often locked into one company’s voice and AI model.

Booking in your EHR

Books directly into your EHR’s open slots, then texts the patient a confirmation.

Often takes a message, or books into a separate calendar your staff re-enter.

Testing before it picks up

Every day, 184 practice calls try to trip it up. Calls it gets wrong become new tests, and a person checks every fix.

Mistakes show up on real patient calls and get fixed afterwards.

Your clinic’s rules

Your team sets the greeting, voice, visit types, providers and transfer list, and keeps answers up to date. Changes apply on the next call.

Often a fixed script, or changes that go through the vendor.

Handing off to staff

Warm transfers with a short summary, staying on the line until a person picks up. 93% of transfers completed.

Often a cold transfer or a voicemail.

Patient privacy

Checks name and date of birth before sharing anything. Until they match, the system blocks the chart. BAA with every customer.

Often told not to share patient details, with nothing in the system to stop it.
