Does it integrate with Opera Cloud and Mews? Yes — Opera Cloud via the OPI, Mews via OAuth. Cloudbeds, Stayntouch, RoomMaster, ResNexus, Little Hotelier are also supported.
Can it hold a room for a 1am arrival? Yes. The agent extends the auto-cancel timer in the PMS and posts a note to the front-desk shift handoff. Most properties see ~8 saved late arrivals per month.
What about loyalty program lookups (Hilton Honors, Marriott Bonvoy)? Yes — through the property's PMS or a direct integration with the OTA's loyalty endpoint. The agent confirms loyalty tier and applies the right amenity entitlements.
Will it sound like a typical IVR? No. We ship hospitality-tuned ElevenLabs v3 voices — warm, on-brand, expressive enough to handle "my room is freezing" without sounding scripted.
Can it route a real medical emergency? Yes. The agent's first action on a confirmed medical call is to advise calling 911. Second action is to dispatch the manager on duty and notify the front-desk supervisor. Logged with timestamps.
