Why it costs less than an answering service
No call center
There's no room full of operators to pay for. That cost never lands on your bill.
Kai answers every call
Day or night, Kai picks up, takes the details, and gets them to you.
No per-minute charges
Kai Line is $79 a month, flat. A long call costs the same as a short one.

$79/mo, ~170 Kai-answered calls/mo.
This estimate assumes each missed call becomes a customer. Actual results depend on how many callers buy and the value of those sales. Optional services and taxes are excluded from the plan cost shown.
