GreetKeeper vs Slang.ai
Slang.ai built an AI for restaurant phones and charges from $399 a month per location for it. What Slang.ai doesn't publish is how many calls that covers, because no call or minute allowance appears at any tier. GreetKeeper prints both: $49 for 200 answered calls, $0.45 for each one after, with booking on every plan.

Why people move off Slang.ai
One vendor's specific wall, not a general complaint about the category.
Per-location pricing is simple until you have locations. Five sites at $399 is a five-figure annual line for answering the phone, and the suburban restaurant that takes nine calls a day pays what the flagship pays. The second reason is the blank space where the allowance should be. With no published call or minute volume, you can't tell whether a busy Friday costs anything extra, and you can't model what growth does to the bill.

What GreetKeeper does differently from Slang.ai
- Slang.ai publishes no call or minute allowance at any tier. Ours is printed: 200, 750 or 2,000 answered calls.
- Our entry plan is $49 against their $399 per location.
- Our overage rate is published, from $0.45 down to $0.25 a call.
- It answers calls that arrive together, so the Friday 6pm rush never hears a busy tone.
- You can set closure dates, and it answers as closed on those days, holidays included.
- It reads the name, number and time back before it books.
What a busy month costs on each meter
The headline price tells you about a quiet month. This is the other one.
Slang.ai scales by site: from $399 a location on Core, from $599 on Premium, Enterprise on request, with no volume published at any tier. Each new restaurant adds at least another $399, however the phones actually ring. Our plans scale by answered calls instead: $49 for 200, $149 for 750, $349 for 2,000, with the overage printed. A small second site can share an allowance rather than buying its own subscription, with its own hours and greeting.
| Plan | Monthly | Calls included | After that |
|---|---|---|---|
| StarterFor a single location taking calls one line at a time. | $49 | 200 | $0.45 per call |
| ProfessionalBooking, routing and transfers included, not an add-on. | $149 | 750 | $0.35 per call |
| ScaleFor busy phones and longer opening hours. | $349 | 2,000 | $0.25 per call |
Moving off Slang.ai in practice
The technical part is a forwarding change. The rest is the part nobody warns you about.
The reservation system is the whole job. Slang.ai is built around restaurant booking flows, so leaving means checking that whatever answers your phone next can still write into the booking platform you use, handle a party-size change, and take a waitlist name at 7pm on a Saturday. Read our integration matrix first. GreetKeeper writes natively to Google Calendar and Outlook, and sends a signed webhook on every booking for anything else you run.
Questions people ask about this comparison
How many of my calls does Slang.ai's $399 cover?
They don't say. No call or minute allowance is published on any tier, so there's nothing to compare consumption against. Our $349 Scale plan covers 2,000 answered calls with $0.25 for each one after. Whether that's better for you depends on volumes only you can see.
How does a reservation reach my system?
GreetKeeper books natively into Google Calendar and Outlook. For any other platform, it sends a signed webhook with the caller's name, number and requested time the moment the booking is made. Our integration matrix names each route, platform by platform.
I run four restaurants. What do you each charge me?
Slang.ai charges per location, from $399 a site on Core, so the bill grows with every site you add. Our plans count answered calls, and multi-location terms start from $299 a location with the volumes written into the contract. Get both quoted against your real call counts.
