If your business is one owner and a phone that rings during jobs, this is the shortest useful comparison we can write. The bar isn’t “can this thing sound like a person.” All four of these do. The bar is: what does the plan you can actually afford include, and where does the feature you actually need (booking a job, transferring to your on-call tech) sit on the price ladder.
Who this guide is for
Owner-operators of small local service businesses: HVAC, plumbing, electrical, cleaning, salons, med spas, small clinics, solo law and accounting practices, home services generally. If your week is mostly on the job and your phone goes to voicemail more often than you’d like, you’re the reader. If your calls are complicated enough that a wrong answer costs you a client (regulated intake, legal conflict checks, sensitive medical questions), skip ahead to Smith.ai. Every other option here’s a pure AI receptionist and can’t escalate to a real person.
Our pick: Rosie
Rosie’s Scale plan is $149 a month and adds in-call calendar booking, warm transfers, live transfers, and mid-call texting on top of the entry Professional plan, and Growth is $299 for 2,000 minutes with waterfall transfers and custom document training.
The reason Rosie ends up as our default recommendation is that the ladder is honest.
The Professional plan at $49/month is real: 250 minutes, spam filtering, message taking and answers to questions from your business content, with appointment booking, direct transfers, and mid-call texts locked to the $149 Scale plan.
A solo owner who wants “the AI takes a message and texts me a summary” gets what they paid for. A busier operator who needs “the AI books the appointment in my calendar before the caller hangs up” pays $149, which is still less than a live answering service.
Setup is the other thing to notice.
Rosie sets itself up from your Google Business Profile, website, or basic business details (company name, industry, services) and can be trained on your business for accurate, professional interactions.
For a business already publishing a clean Google Business Profile, that’s ten minutes of work. (If your Google profile isn’t where it should be, our Google Business Profile post scheduler guide is the neighbor to this one.)
The honest downside is the overage story.
Rosie’s pricing page doesn’t state what happens past your minutes; Rosie’s own blog describes an automatic upgrade to the next tier, while third parties report a $0.25-per-minute overage, and the pricing page itself is silent.
If you consistently run near your minute ceiling, get the current policy in writing before you sign up.
The unique-caller alternative: Goodcall
Goodcall is worth understanding even if you don’t pick it, because its pricing model is the clearest counter-argument to per-minute billing in the category.
A “unique customer” is any caller with a unique phone number that actually says something to the agent in a given month. A single client who calls ten or more times only counts as one unique customer, so long as they always call from the same phone number, and there are no additional charges or fees for a long call.
Goodcall offers three subscription tiers for its AI receptionist: $59 for Starter, $99 for Growth, and $199 for Scale per agent, billed monthly, with annual billing taking 30% off each plan. Pricing is based on the number of unique callers, and each plan includes unlimited minutes and tokens, with $0.50 charged per extra unique customer once the limit is reached.
Third-party pricing coverage in 2026 reports a slightly different published ladder ($79, $129, $249 per agent), so
verify the live page: Starter includes 100 unique callers and unlimited minutes, Growth 250 callers, and Scale 500, with extra callers billed at $0.50 each and 15 percent off for annual billing
.
The shape to watch is the caller cap when your business is trying to grow.
Goodcall caps unique callers, so every new lead from your marketing counts against the cap; that’s backwards for anyone actively trying to grow inbound.
Fine for a maintenance-contract business or a property manager. Wrong for a shop actively spending on Google Ads.
Multi-location owners should also do the math carefully.
GoodCall’s $79 Starter price is per agent, not per account. Each agent is tied to one phone number, typically one location or one line, so one location with one phone line is 1 agent and $79/month, and two locations with separate numbers is 2 agents and $158/month on the Starter tier.
The human-backup pick: Smith.ai
Smith.ai is the only service on this page that combines an AI receptionist with a real, employed human on the same platform. That’s the whole reason to consider it.
With the AI Receptionist, calls are always handled by AI first, but if something complex comes up, the call can be transferred to a live North America-based receptionist any time, day or night. This built-in human backup means callers get the help they need while you don’t get interrupted.
The free tier is the fact most third-party reviews get wrong.
Smith.ai’s AI Receptionist has three plans as of September 2026: Free at $0 for 25 calls a month (then $3.00 per call), Pro at $150 a month for 75 calls, and Enterprise at $500 for 300 calls. A volume selector offers 75, 150, or 300 calls per month, pricing at $150 (75 calls, $2.00/call), $270 (150 calls, $1.80/call), and $500 (300 calls, $1.67/call), with overage of $2.50, $2.30, and $2.17 per call by setting.
That $0 tier is a real product, not a demo trick, and it’s the cheapest way to hear how Smith.ai handles your callers.
The human line is what makes Smith.ai’s numbers big.
The human-staffed Virtual Receptionist has three plans plus custom: Starter at $300/month for 30 calls with $11.50 overage per call, Basic at $810/month for 90 calls with $10.50 overage, and Pro at $2,100/month for 300 calls with $8.50 overage. The human plans carry a 10% discount for a 12-month subscription, no setup fees, and 24/7 staffing at no extra charge; calls at 2 pm and 2 am cost the same.
There’s also a real cancellation policy worth knowing about.
AI Receptionist is a month-to-month service with no long-term contracts; you pay for the AI Receptionist service each month, and cancellation requires 30 days’ notice by email.
If a self-serve cancel button is a hard requirement for you, that’s the thing to know before signing up.
The budget experiment: Dialzara
Dialzara’s job on this page is honest. It’s the cheapest verified way to find out whether an AI receptionist works for your callers, your accents, and your industry vocabulary.
Dialzara’s inbound plans are Business Lite at $29/mo (60 minutes, $0.48/min overage), Business Pro at $99/mo (220 minutes, $0.45/min), Business Plus at $199/mo (500 minutes, $0.40/min), and Business Elite at $349/mo (1,000 minutes, $0.35/min). There’s no setup fee and every plan includes a 7-day free trial, with add-ons for an AI SMS agent ($19/mo + $0.05/message), a website chatbot ($39/mo), and outbound voice from $750/mo.
Two catches to read before you pay. First, the entry plan isn’t quite what it looks like on the shelf.
The plan table is the trap: Lite gets message taking, blind transfer, and Zapier or Make. Warm transfer, after-hours rules, bilingual English and Spanish, and Google or Outlook calendar sync start at Pro.
A trades business or salon that assumes $29 buys a bookable receptionist is going to be disappointed. $99 is the real “this can book a job” price.
Second, sixty minutes is thin.
The $29 plan holds 60 minutes, which is roughly one call a day; treat it as a trial tier, not a working plan.
On the upside,
a call past the allowance costs about the same as a call inside it, which is unusually honest, and the reason this ladder is easy to reason about
. If you’re testing the category, Dialzara is a rational $29. If you already know you need a real receptionist, price Pro at $99 or move to Rosie Scale at $149 for more minutes and included booking.
How to choose between them
If your callers are new leads and you want the AI to book a job before the caller hangs up, Rosie Scale at $149 is the shape that fits, and its Professional tier at $49 is a reasonable trial if you’re fine texting a booking link instead. If your callers are mostly the same regulars month after month and you hate the idea of paying by the minute, Goodcall’s per-caller model is the honest counter-argument. If a wrong answer on the phone would cost you a client, buy Smith.ai and use the human plans. If you just want to know whether the whole category works for you, start on Smith.ai’s free AI tier or Dialzara Lite at $29 and graduate when the answer comes back.
The one thing we wouldn’t do is run two of these at the same time on the same line. Pick the shape that matches your call profile, count last month’s minutes and unique callers before you sign up, and re-check the pricing page before renewal.
