Forty-two tools in this directory answer an inbound phone call or qualify an inbound lead. Nine of them publish a monthly price. Here they are, cheapest first.
| Tool | Entry | Free tier | Buy without a call? |
|---|---|---|---|
| Chatbase | $40/mo | Yes | Yes |
| Landbot | $45/mo | Yes | Yes |
| Rosie | $49/mo | Yes | Yes |
| Goodcall | $79/mo | Yes | Yes |
| Parakeet | $199/mo | No | Yes |
| Slang.ai | $399/mo | No | Yes |
| Sameday AI | $449/mo | No | Yes |
| Structurely | $598.80/mo | No | No |
Retell for Healthcare is the ninth. It publishes a $0 entry and $0.07 a minute on top, which is a different pricing model and is why it sits outside the table rather than at the head of it.
The spread is fifteenfold, and the job is the same
From $40 to $598.80 is a 15x spread across products that describe themselves in nearly identical language: answer the phone, take a message, book an appointment, do it around the clock.
Two things explain most of it. The cheap end is chat rather than phone, and the expensive end bundles integration work into the subscription. Chatbase at $40 and Landbot at $45 are chatbot builders that can be pointed at a phone number; Slang.ai at $399 and Sameday at $449 arrive configured for a specific industry with the booking integration already built.
Neither of those is on a pricing page. You find out which kind of product you bought after you buy it.
Thirty-three publish nothing
The other 33 tools publish no price at all, and 31 of the 42 cannot be bought without talking to somebody first. That is 79% of the lane behind a form.
This is worth stating as a finding rather than a complaint. A market where four fifths of vendors will not name a number is a market where the published prices are doing more work than they should, because they are the only anchors a buyer has. The nine above are not the cheapest nine. They are the transparent nine.
The number nobody publishes: calls per month
Not one of the nine states how many calls the monthly fee covers. That omission is what makes the whole category incomparable, because a flat fee and a per-minute rate cannot be set against each other until somebody fixes the volume.
So fix it. This site computes a component floor of $0.0465 a minute for a voice agent, built from four dated published rates for recognition, language, synthesis and telephony. That figure is what the underlying minutes cost before anybody adds a margin, and it lets a monthly price be expressed as the volume at which it stops being a bargain.
| Tool | Monthly | Break-even minutes | At 4-minute calls |
|---|---|---|---|
| Rosie | $49 | 1,054 | ~264 calls |
| Goodcall | $79 | 1,699 | ~425 calls |
| Parakeet | $199 | 4,280 | ~1,070 calls |
| Slang.ai | $399 | 8,581 | ~2,145 calls |
| Sameday AI | $449 | 9,656 | ~2,414 calls |
| Structurely | $598.80 | 12,877 | ~3,219 calls |
Read the middle column as the point where the subscription costs the same as the raw minutes it is buying. Below that line you are paying for the software and the setup; above it you are paying less per minute than the components cost, and the vendor is betting you stay below.
A single-location dental practice taking 300 calls a month is nowhere near any of these lines. That is the honest shape of the category: for a small business, almost every plan here is priced above its own component cost, and the gap is the product. Whether that gap is worth paying depends entirely on whether the integration and the prompt work are things you would otherwise do yourself.
Who else answers this question
We bought the search result for this query on 14 August 2026. It returned Reddit at positions one and six, six vendors, and no independent publisher anywhere on the page.
The top result is somebody on r/EntrepreneurRideAlong who priced the tools by hand and posted the list. That is the same work this page does, and the fact that it outranks every vendor is the clearest signal available that buyers are not getting the answer from the people selling.
