Smith.ai charges $8.50–$11.50 per call on its human plans and $2.17–$3.00 per call on its AI plans. Here are seven alternatives with every price read off the vendor's own page on 9 September 2026 — Rosie, Goodcall, Ruby, PATLive, Slang.ai, a DIY build on Retell or Bland, and a custom build — plus the three situations where Smith.ai…
Most pages ranking for this question are written by one vendor who wants to be the answer. This one names seven, publishes what each actually charges, and tells you where Smith.ai still wins. We sell one of the seven — the last one — and it is the wrong choice for most people reading this.
Short answer: if you want cheap AI answering, Rosie ($49/mo, 250 minutes) or Goodcall ($79/mo, 100 unique customers, unlimited minutes) will beat Smith.ai on price by 80–95%. If you want humans, Ruby ($250–$1,725) and PATLive ($49–$6,899) are the direct substitutes and PATLive is usually cheaper per minute. If you want an agent wired into your own CRM, calendar and pricing rules, no packaged product does that and you are looking at a build. Smith.ai remains the best pick when you need live North American humans on a low monthly commitment and don't want to run anything yourself.
You cannot compare alternatives to a price you don't have. Smith.ai publishes two separate ladders on two separate pages, and most comparison articles only find one of them.
AI-first receptionist
| Plan | Monthly | Included calls | Overage |
|---|---|---|---|
| Free | $0 | 25 | $3.00 per call |
| Pro | $150 | 75–300 (tiered) | $2.50–$2.17 per call |
| Enterprise | $500 | 300–1,000+ (tiered) | $2.17 per call to custom |
Human-first receptionist
| Plan | Monthly | Included calls | Overage |
|---|---|---|---|
| Starter | $300 | 30 | $11.50 per call |
| Basic | $810 | 90 | $10.50 per call |
| Pro | $2,100 | 300 | $8.50 per call |
| Enterprise | Not published | Custom | Custom |
Two things fall out of that table immediately.
The first is that Smith.ai bills per call, not per minute, on both ladders. That is unusual, and it changes which businesses it suits. A practice whose calls run ninety seconds each is subsidising a competitor whose calls run nine minutes. If your calls are short, per-call billing is expensive; if your calls are long, it is a bargain nobody else will match.
The second is that the AI tier is still $2.17–$3.00 a call. Raw AI voice infrastructure runs $0.07–$0.31 a minute. Even at a generous five-minute average, Smith.ai's AI plan carries a healthy margin over the underlying cost — which is fine, that is what a product is, but it means "their AI plan" is not the cheap end of the market. It is the middle.

| Option | Entry price | Billing unit | Humans? | Best for |
|---|---|---|---|---|
| Rosie | $49/mo | Minutes (250 / 1,000 / 2,000) | No | Cheapest credible AI answering |

Rosie is the answer to "I just need the phone answered and I don't want to think about it." At $49 for 250 minutes you are paying $0.196 a minute all-in, which is inside the range raw infrastructure costs and roughly a tenth of what a human service charges.
Where it beats Smith.ai: on price, decisively, and on the billing unit if your calls are short. Two hundred and fifty minutes covers about 125 two-minute calls. The equivalent 125 calls on Smith.ai's AI Pro tier is $150 plus fifty overage calls at $2.50 — call it $275. On the human ladder it is over $1,000.
Where it loses: no live human, ever. Overage rates are not published, which is a real gap when you are budgeting — ask before you sign. And like every packaged product it knows nothing about your business beyond what you type into its setup form.
$79 / 100 unique customers · $129 / 250 · $249 / 500 (per agent). Unlimited minutes and tokens. $0.50 per extra unique customer. 15% off annual.
Goodcall is the only vendor here billing by unique caller, and that single decision makes it either the cheapest option on this page or a bad deal, with almost nothing in between.
It is the cheapest if your callers repeat or your calls run long. A property manager whose 80 tenants call four times a month each is billed for 80 customers, not 320 calls, and the minutes are unlimited — so a twelve-minute maintenance call costs the same as a thirty-second one. Against Smith.ai's per-call meter that is a rout.
It is a bad deal if every caller is new and brief. A contractor taking 300 cold inbound leads a month burns 300 unique customers: $249 plus overage. Rosie would charge $149 for the same traffic.
Run this test before anything else: divide your monthly calls by your monthly distinct phone numbers. Above about 2.0, look hard at Goodcall. Below 1.3, don't.
$399/mo · $599/mo · custom. Flat, billed per location.
Slang.ai is purpose-built for hospitality — reservations, hours, "are you open on Labor Day", the specific call shape a restaurant gets — and it does that well. It is on this list for completeness, not because it is a general Smith.ai substitute.
The structural warning is per location. Three restaurants is $1,197 a month at entry tier. Multi-site operators consistently find the arithmetic turns against them somewhere around the third or fourth location, at which point a single agent with location routing is dramatically cheaper.
$250 / 50 min · $395 / 100 · $720 / 200 · $1,725 / 500. Chat from $143 / 10 chats. Bundles from $115.
Ruby is the closest like-for-like replacement for Smith.ai's human plans and the one most often shortlisted alongside it, particularly by law firms.
The comparison is not straightforward because Ruby bills minutes and Smith.ai bills calls, so the winner depends entirely on your average call length. At 500 minutes for $1,725, Ruby is $3.45 a minute. If your average call is three minutes, that's $10.35 a call — line ball with Smith.ai's $8.50–$11.50. If your average call is ninety seconds, Ruby is $5.18 a call and Smith.ai is materially more expensive. If your calls run six minutes, Ruby costs twice as much.
Pull your carrier's average call duration before you choose between these two. It is the only number that decides it, and almost nobody looks it up.
$49 pay-as-you-go at $2.99/min, then $99 / 50 min ($2.29), $189 / 100 ($2.09), $349 / 200 ($1.99), $479 / 300 ($1.89), $759 / 500 ($1.79), $1,499 / 1,000 ($1.69), up to $6,899 / 5,000 min ($1.49).
PATLive publishes the most honest ladder in the human category: eleven tiers, the effective per-minute rate falling from $2.99 to $1.49 as volume rises, no games.
At 500 minutes PATLive charges $759 where Ruby charges $1,725. That is 56% less for the same unit of the same service. Ruby has the stronger brand and the deeper legal-vertical integrations; whether that is worth a 2.3x premium is a real question and the answer is often no.
Against Smith.ai, PATLive wins on any call longer than about five minutes and loses on very short ones — the per-call versus per-minute pivot again.
Retell: $0.07–$0.31 per minute, all-in, breakdown published. Bland: $0.14 / $0.12 / $0.11 per minute with a $0 / $299 / $499 monthly platform fee, all-in.
If you have a developer, this is where the cost floor actually is. At $0.14 a minute, a thousand minutes of answered calls costs $140. The same thousand minutes on Ruby is roughly $3,450.
The costs that don't appear on those pricing pages are the real ones: someone has to write the prompt, wire the telephony, test the handoff, and own it at 2am when it starts confidently giving out the wrong hours. Budget 20–60 engineering hours to get to something you'd let talk to a customer, plus ongoing maintenance. That is the trade — you are swapping a monthly fee for a permanent internal responsibility.
Ignore the headline-rate comparison between platforms. Vapi's $0.05 is hosting only — model, speech-to-text and speech synthesis bill on top, landing real usage around $0.13–$0.33. Bland's $0.14 already includes all of it. The cheapest-looking number on that market is usually the least complete one.
TrainYourAgent: $2,500 build + $497/mo (Agent in a Day), $7,500 + $2,950/mo (Operators), $9,950 + $4,997/mo (Scale). Current figures on the pricing page.
Here is the disqualifier, stated plainly: if all you need is for someone to answer the phone, do not hire us or anyone like us. Rosie at $49 does that. Paying a build fee for a capability you can rent for the price of a phone bill is money set on fire, and an agency that takes that engagement without telling you is not one to hire.
A build earns its cost only when the agent has to touch systems a packaged product cannot see: reading live availability out of your calendar, applying your own pricing rules to quote on the call, writing a qualified lead into your CRM with the fields your sales process needs, escalating on your on-call rota, following your intake script for a regulated intake. That is a different product from answering a phone, and it is the only reason to pay build money.
If you're not sure which side of that line you're on, the question to ask is: would a competent temp with a script and no access to our systems handle 90% of these calls? If yes, buy a packaged product.
Three situations, and they are not rare.
You need live North American humans and you need them now. Smith.ai's agent network is mature, staffed, and available today. No AI product on this page can take a distressed caller, exercise judgment, and de-escalate. If a meaningful share of your calls are emotional, high-value or legally sensitive, that capability is worth paying for and $300 a month is not much to pay for it.
Your calls are long. Per-call billing is a gift to anyone whose average call runs past five or six minutes. At a ten-minute average, Smith.ai's Pro tier works out around $0.85 a minute against PATLive's $1.49 and Ruby's $3.45 — Smith.ai is the cheapest human option on this page and it isn't close.
You want one vendor for AI and humans with a real escalation path between them. The hybrid model — AI takes the routine call, a human picks up the hard one — is genuinely useful and Smith.ai is one of the few running both sides itself. Stitching Rosie to PATLive gets you two vendors, two bills and a handoff nobody owns.
What is the cheapest Smith.ai alternative? Rosie at $49/month for 250 minutes is the cheapest packaged AI option, and PATLive's $49 pay-as-you-go plan is the cheapest way to keep a human on the line — though PATLive bills $2.99 a minute on top of that, so it is only cheap at very low volume.
Is there a free Smith.ai alternative? Smith.ai's own AI tier has a free plan with 25 calls a month, which is usually the best free option available. Beyond that, building on Retell or Bland has no platform fee at the entry tier, but you pay per minute and supply the engineering.
Which alternative has live human receptionists? Ruby and PATLive. Everything else on this list is AI-only, and a custom build escalates to your own staff rather than to a stranger.
How do I compare per-call pricing to per-minute pricing? Multiply your average call duration by the per-minute rate to get a per-call figure, then compare. Most businesses have not measured their average call duration, and it is the single number that decides this entire question — your phone provider's call log has it.
Does Smith.ai have a contract? Their published plans are monthly. Check current terms directly; this page tracks prices, not contract language.

Prices move. If you are reading this well after that date, treat the structure — per-call versus per-minute versus per-customer, and which one suits your call shape — as the durable part, and re-check the numbers.
