A digital concierge your patients actually talk to.
Avery greets visitors, answers in natural speech, and shows the right on-screen
card at the right moment — directions with a scan-to-go QR, hospital info, check-in, and
scheduling. One conversational core, any avatar vendor, sub-1.5-second responses.
▶ Live two-way conversation — an AI visitor talks to Avery in real time;
the cards on the right are driven by the conversation, not scripted.
What it does
Speech in. The right card out.
Every answer Avery speaks can surface a matching on-screen card — generated live
from the conversation through a barge-in-aware overlay engine.
Wayfinding
Turn-by-turn directions to any department or amenity, plus a QR to carry the route on a phone.
Hospital info
Visiting hours, parking, policies, amenities — answered in plain language, shown as a card.
Check-in
Looks up the appointment and marks arrival — a FHIR-shaped flow against synthetic records.
Scheduling
Books, reschedules, and sets follow-ups — the same normalized appointment view, any backend.
Built for production
Fast enough to feel human.
Conversation latency is the make-or-break for an avatar. We measure it every run
against a hard acceptance gate.

Architecture
One core. Any avatar. Any EHR.
Transport-blind core — the same conversational brain runs on Tavus or HeyGen; the avatar vendor is a swap, not a rebuild.
Overlay engine — cards are timed to the avatar's speech and retracted on barge-in, so the screen always matches what's said.
Latency masking — slow tool calls (lookups, booking) are covered by a spoken acknowledgement so the conversation never stalls.
FHIR-shaped & EHR-agnostic — one normalized appointment view over mock, open FHIR, or Epic-read; flip the backend, not the app.
Synthetic by default — every patient and appointment shown is fictional; no real PHI ever touches the demo.
Measured, not claimed — an ongoing probe tracks p50/p95 latency against the acceptance gate, run over run.
All people, appointments, and the "St. Anywhere General Hospital" setting shown here are
synthetic and unencumbered — a reference scenario used to validate the platform, not real patient data.

The best way to judge an avatar is to talk to one. Book a short call and we'll put you in
a live conversation with Avery — wayfinding, check-in, scheduling, the works.
