AI booking agent that confirms appointments and slashes no-shows.
Clinics, salons, and service businesses lose 15–30% of revenue to no-shows. Yuki confirms by voice, reminds by WhatsApp, and reschedules in real time. In 40+ languages.
Who it's for
- Medical, dental, and aesthetic clinics losing chair time to no-shows
- Salons, spas, and personal-trainer studios with high cancellation churn
- Home-services businesses (plumbing, HVAC, cleaning) where dispatch costs are heavy
- Multi-location franchises that need consistent booking voice across regions
How it works
- 1
Booking lands in your calendar
Calendly, Cal.com, Booksy, Fresha, or your custom system fires a webhook to Callsy. Yuki picks it up within seconds.
- 2
Yuki confirms by voice or WhatsApp
Same day. Confirmation call or WhatsApp message in the customer's preferred channel and language. The morning of the appointment, she pings again with the address, parking, and any prep instructions.
- 3
Live reschedule if needed
If the customer can't make it, Yuki offers the next 3 open slots, books the swap on the call, and notifies the practitioner. No phone tag, no empty chair.
Why it works
- Voice confirmation lifts show rates dramatically over SMS-only. Patients who hear a human (or human-like) voice commit more reliably.
- WhatsApp open rates exceed 95% in regions like LATAM, India, and Southern Europe. Far above any email reminder.
- Real-time rescheduling on the call eliminates the no-show-because-they-couldn't-cancel pattern, which is the #1 cause of empty slots.
- Yuki speaks 40+ languages with 60+ voices. Including 8 regional Spanish variants, Lithuanian, Hindi, Mandarin, and Arabic.
- HIPAA-eligible on the Scale plan for US healthcare deployments.
What the call sounds like
Hi Sarah, this is Yuki from Brightleaf Dental. Just an AI-assisted confirmation for your Tuesday 3pm cleaning with Dr. Park. Is that still good for you?
Actually, I'm not going to make 3. Could we push it later?
No problem. I've got 4:30pm Tuesday open, or Thursday 11am if that's easier.
Thursday 11 is perfect.
Great, booked. I'll send the confirmation to WhatsApp now, plus a parking note. The clinic's covered lot is half-price after 10am with validation.
Thanks, that's super helpful.
What it delivers
Frequently asked
Does Yuki work with my booking system?
Yes. We have native integrations for Calendly, Cal.com, Acuity, Booksy, Fresha, and any system that exposes a webhook. Custom systems integrate via Make or Zapier in under an hour.
Can she handle reschedules live on the call?
Yes. Yuki checks live availability in your calendar and books the swap before hanging up. No "someone will call you back" loop.
What languages and accents does she support?
40+ languages and 60+ regional voices. For multi-location franchises we typically match accent to region. A Madrid clinic gets es-ES, a Mexico City clinic gets es-MX, automatically.
Is this HIPAA-compliant for US healthcare?
Yes, on the Scale plan. We sign BAAs, route US healthcare calls through HIPAA-eligible infrastructure, and redact PII from transcripts on request.
Can I customize her voice and persona to my brand?
Yes. Pick from 60+ stock voices, or clone your own brand voice (subject to consent) on the Pro and Scale plans.
