Comparisons · verified, dated, sourced

The AI receptionist market, compared honestly.

Every competitor price on this blog was read off that vendor's own public pricing page and stamped with the date we checked it. Where a competitor is genuinely the better choice for you, we say so on the page. We'd rather lose a bad-fit customer than win one with a number we made up.

Alternatives

The whole field for one vendor — every option, what each really costs, and who each one suits.

Smith.ai alternatives: what you actually pay per call
Smith.ai starts at $300/month for 30 calls, then $11.50 for every call after. We break down the real per-call maths against flat-rate AI, and name the cases where Smith.ai's human receptionists are still worth it.

Alternatives
Rosie AI alternatives: read the tier, not the headline price
Rosie's $49 plan is cheaper than WarmLane — but it can't book appointments or transfer calls. Booking starts at $149/month. Here's the like-for-like comparison at the tier that actually does what you need.

Alternatives
Goodcall alternatives: same $79, very different ceiling
Goodcall Starter and WarmLane cost exactly the same. The difference is what happens at customer 101, how long your call history survives, and whether you build the thing yourself.

Alternatives
Ruby Receptionists alternatives: the $5-a-minute question
Ruby's entry plan is $250/month for 50 minutes of receptionist time. That's real humans and it shows — but 50 minutes is under two minutes a day. Here's when that maths stops working.

AnswerConnect alternatives: you can't see the price
AnswerConnect doesn't publish plan pricing — you fill in a form and wait for a call. We document what is public, and make the case for knowing your bill before you talk to anyone.

Head-to-head

Two products, compared in depth — for when you've narrowed it down and just need to decide.

Head-to-head
WarmLane vs Smith.ai
Flat $79 AI against $300 for 30 human-answered calls. Smith.ai costs more than us from the eighth call of the month — which is exactly why price shouldn't decide this one. The judgement question should.

Head-to-head
WarmLane vs Rosie
Rosie's $49 tier beats us on price and we say so. But it can't book appointments — that's $149. Two separate contests, depending on whether you want a message or an appointment.

Head-to-head
WarmLane vs Goodcall
Identical $79 price, so price decides nothing. What decides it: the 100-customer cap, the 7-day call history window, and whether you build the agent or we do.

Neutral comparison
Rosie vs Smith.ai
Neither of them is us. AI minutes against human calls, with a 14× cost gap at matched volume — and an honest account of what that gap actually buys you.

Developer platforms
Synthflow vs Retell vs Vapi
If you'd rather build it yourself. Vapi at $0.05/min, Retell at $0.07–$0.31/min, and Synthflow — which has quietly moved to $30,000/year minimum. Plus everything the per-minute rate doesn't cover.

Buyer's guide
AI receptionist vs human answering service

AI receptionist vs voicemail: measure your own number
Nearly every missed-call statistic you've read was published by a company selling the fix, and they contradict each other. Here's who publishes what — and how to measure your own rate instead.

By industry

The same market, judged against how your particular phone actually rings.

Industry guide
For plumbers, HVAC and home services
Trade calls are short, routine and violently spiky. We price a normal month against a storm week — where per-call billing turns your best week into a $3,800 invoice — plus emergency triage and service-area filtering.
Read the guide →
Industry guide
For dental practices and med spas
Your front desk isn't absent — it's occupied, and the new-patient call arrives anyway. Covers the 9pm booking case, the clinical triage boundary you must not cross, and the HIPAA questions to ask in writing.
Read the guide →
Industry guide
For law firms
The one category where we'll tell you to buy a human service instead. AI belongs on after-hours capture and booking — never on conflict checks or matter assessment. Where the line falls, and why Smith.ai wins on intake.

How we compare

Our rules for every comparison on this blog.

Every price is read off the vendor's own public pricing page, linked, and stamped with the date we checked. We compare like-for-like tiers, not our best plan against their worst. Where a competitor wins, the page says so in its own section. And we re-verify every quarter — pricing moves, and a stale number is just a wrong number.

Stop reading comparisons. Just call ours.

Every vendor on this blog will show you a demo video. We'll give you the phone number. Ask it anything you'd want it to handle for your customers — then decide.
