Smith.ai runs two pricing ladders on two separate pages, which is why most comparisons quote only one of them. AI plans: $0, $150 and $500 a month, billing $2.17-$3.00 per call. Human plans: $300, $810 and $2,100 a month, billing $8.50-$11.50 per call. Both bill per call rather than per minute, and that single decision is what should…
Per call, not per minute — and it cuts both ways.
Almost every competitor bills minutes. Smith.ai bills calls, so a ninety-second call and a twelve-minute call cost the same. If your average call is short, you are subsidising businesses whose calls run long and you are paying well over the odds. If your calls genuinely run six minutes or more, Smith.ai's Pro tier works out around $0.85 a minute against PATLive's $1.49 and Ruby's $3.45, which makes it the cheapest human answering on the market. Pull your average call duration out of your carrier's call log before you compare anything else. It is the number that decides this, and almost nobody looks it up.
Their AI tier is the middle of the market, not the cheap end.
At $2.17-$3.00 a call the AI plans sit well above the underlying cost of AI voice, which runs $0.07-$0.31 a minute on the infrastructure everyone builds on. That is a normal product margin and not a criticism. It does mean that if price is what sent you looking, Smith.ai's AI tier is not where the savings are: Rosie at $49 for 250 minutes and Goodcall at $79 for 100 unique callers are 60-90% cheaper for the same job of answering a phone.
Where we are a different purchase entirely.
Smith.ai answers, screens and takes a message, and its human network handles the call an AI should not. What it cannot do is read live availability out of your calendar, apply your own pricing rules to quote on the call, write a qualified lead into your CRM with the fields your sales process needs, or escalate on your on-call rota. That is what a build is for, and it is the only thing worth paying build money for. If all you need is the phone answered, buy Smith.ai or something cheaper and keep your money.
When is Smith.ai the better choice than TrainYourAgent?
Three cases, and none of them is rare. You need live North American humans on the line today, and no AI product will de-escalate a distressed caller. Your calls run long, which makes their per-call meter the cheapest human option available. Or you want AI and humans from one vendor with a real escalation path between them, which is genuinely hard to assemble from two vendors.
What is Smith.ai's cheapest plan?
Their AI tier has a free plan covering 25 calls a month, then $150 a month at the Pro tier. The human ladder starts at $300 a month for 30 calls. Figures read off smith.ai on 9 September 2026.
Where this lands in production
The closest thing we run to a like-for-like replacement is Voice Receptionist — the build, the integrations and the running cost. That is the page to read if you want the build, the integrations, and the operating cost rather than the positioning argument.
