The Short Version
Smith.ai is a well-regarded virtual receptionist service that blends live agents with AI to answer calls, qualify leads, and book appointments. Its published plans bill by the call — roughly $97.50 per month for about 30 calls, with overage charges in the range of $2.40 to $2.70 per additional call — so your monthly bill rises with your call volume. Smith.ai also backs its service with a 30-day money-back guarantee, which is a genuine plus for buyers who want that reassurance.
Hire Kayla takes a different approach: a flat $99 per month for an AI receptionist that answers every call, with no per-minute charges and unlimited inbound calls under fair use. You set Kayla up yourself in under 10 minutes, every call is transcribed to your dashboard, and pricing stays the same whether you take 30 calls or 300. The two services solve the same problem from opposite directions — human-in-the-loop billed per interaction, versus self-serve AI at a predictable flat rate.
