Smith.ai is a solid service, and its free plan covers 25 calls a month. The trouble starts when you grow past that. Every call costs the same, so a quick "Are you open Saturday?" costs as much as a long call from a new customer, and a business with lots of short calls pays for all of them. If that per-call pricing doesn't fit, Cally24 is our top pick: $99 a month with 240 minutes, with booking and Spanish on one plan. Rosie, Dialzara, Goodcall and Ruby are worth a look too.
Prices checked October 25, 2026 on each company's public pricing page. Prices change, so check before you buy. Cally24 is our product, so we've kept every other listing to what their own pages say.
What to look for
Start with how it counts. Per minute, per call and per caller can give very different bills for the same month, so think about whether your calls are mostly short or long.
Then check what's on the plan you'd actually buy. Booking into your calendar and Spanish are sometimes only on a bigger plan, which changes the real price. Last, decide who should answer: an AI, or live people at a much higher price.
The options
Cally24. An AI receptionist at $99 a month with 240 minutes, then $0.29 a minute. Booking, Spanish and every other feature are on the one plan.
Rosie. An AI service at $49 a month for 250 minutes, with Spanish. Booking into your calendar starts on its $149 plan.
Dialzara. The lowest entry price, at $29 for 60 minutes. Booking and Spanish both start on its $99 plan.
Goodcall. An AI agent that charges per caller, from $79 for 100 callers. It books into Google Calendar, and its pages don't list Spanish.
Ruby. Live people instead of AI, from $250 for 50 minutes. Scheduling is optional, and Spanish is available.
$99 a month. Cancel anytime.
