GreetKeeper vs Retell AI
Retell AI sells the parts of a voice agent by the minute. You pay $0.07 to $0.31 a minute, and you, or a developer you hire, build the agent that answers. GreetKeeper is the receptionist already built. You pay per answered call from $49 a month, with booking, transfers and transcripts on every plan.

Why people move off Retell AI
One vendor's specific wall, not a general complaint about the category.
Retell AI is a builder's platform, and the people who leave it are usually business owners who never wanted to be builders. A developer can stand up an agent quickly. Keeping it right as your hours, prices and staff change is the part that lands back on your desk. The second reason is the bill. Voice infra at $0.055 a minute, voices at $0.015 and US telephony at $0.015 stack on every call, and the total moves with how long callers talk.

What GreetKeeper does differently from Retell AI
- GreetKeeper is a finished receptionist: point it at your website and it drafts your hours, services and FAQs for you to correct.
- You pay per answered call, from $49 for 200 calls, so a long call costs the same as a short one.
- Booking is on every plan and writes straight into Google Calendar or Outlook during the call.
- Every plan includes a dedicated local number, with the area code you choose at signup.
- A transfer that isn't picked up tries a second number you nominate, and the on-call person gets a text with the caller's details.
- Your first 14 days are free with every feature on, no card and no setup fee.
What a busy month costs on each meter
The headline price tells you about a quiet month. This is the other one.
Retell AI meters minutes, so a busy month and a chatty month look the same on the invoice. The rate is $0.07 to $0.31 a minute depending on the parts you pick. Numbers cost $2.00 a month each, and calls past the 20 free concurrent lines add $8.00 a month per line. GreetKeeper counts answered calls. Scale is $349 for 2,000 calls and $0.25 for each one after that. Robocalls and spam calls are screened out before the greeting and never reach the count.
| 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 Retell AI in practice
The technical part is a forwarding change. The rest is the part nobody warns you about.
Your Retell phone number and agent stay where they are while you test. Sign up for GreetKeeper, pick the area code for your new local number, and point it at your website so it drafts your hours, services and FAQs. Fix what it got wrong, connect Google Calendar or Outlook, and set who a transfer goes to. Then change the forwarding on your business line to the GreetKeeper number. Run a week of real calls, read the transcripts, and switch off the Retell agent when you're happy.
Questions people ask about this comparison
How does Retell AI pricing compare with GreetKeeper?
Per minute, Retell AI starts at $0.07, but the rate climbs to $0.31 with the parts you choose, and the agent is yours to build. GreetKeeper's Starter plan is $49 for 200 answered calls, and each call past that is $0.45. Call length never changes our price.
Do I need a developer to use GreetKeeper?
No. You point GreetKeeper at your website, and it drafts your hours, services and FAQs. You correct the draft, connect your calendar and choose who gets transfers. Your developer can still catch our signed webhook if you want call data in another system.
Can GreetKeeper send call data to my own app, the way a Retell build would?
Yes. GreetKeeper sends a signed JSON webhook for four events: call.completed, booking.created, message.taken and transfer.made. Each one carries the caller's details, the summary, your intake answers and a link to the transcript. It's signed with HMAC-SHA256 and retried if your server doesn't answer.
How many calls can GreetKeeper answer at once?
GreetKeeper answers calls that arrive together at the same time, so nobody waits in a queue. It's included on every plan, with no per-line fee.
