When each platform wins

Smith.ai is better when

  • • You specifically need live human receptionists, not just AI.
  • • You're a law firm, accounting practice, or other professional service with predictable, low call volume.
  • • You already have a robust CRM, calendar, and billing stack and just want to plug a phone layer in.

Kairvio is better when

  • • You're a service business — trades, home services, recurring service plans.
  • • You want the AI to book jobs in real time on your calendar.
  • • You don't already have an FSM tool and want phone, scheduling, invoicing, and payments in one app.
  • • Per-call or per-minute pricing would get expensive at your call volume.

FAQ

Is Kairvio a Smith.ai alternative?
Yes. Kairvio includes a 24/7 AI voice receptionist plus an AI text and social DM assistant — covering the same use cases as Smith.ai, plus the rest of the operations stack (calendar, invoicing, payments, CRM) in the same app.
How does pricing compare to Smith.ai?
Smith.ai charges per call or per minute (typically $25–$50/mo for low volume, escalating fast at higher call counts). Kairvio is flat-rate ($79–$349/mo) with AI included on Pro and above. For most service businesses with 50+ inbound calls per month, Kairvio is significantly cheaper.
Does Kairvio have human receptionists like Smith.ai?
No — Kairvio's receptionist is AI-only. If you need a live human virtual receptionist, Smith.ai or Ruby may fit better. If you want AI that books jobs into a calendar and is part of the platform running your invoices and customer records, Kairvio fits better.
Will the AI book appointments on my calendar?
Yes. Kairvio's AI receptionist sees your real calendar and books appointments in real time. The customer hangs up with a confirmed booking, not a callback request.
