Prosper AI is a real product with real customers, and for some practices it is the right choice. This is not a takedown. It is the comparison we would want if we were the ones evaluating.
The short answer
The main alternatives to Prosper AI are Infinitus, SuperDial, Assort Health, and Agentman. Infinitus and SuperDial sell to enterprise buyers — payers, pharma, and RCM companies. Assort Health and Prosper both target practices and specialty groups. Agentman differs in scope rather than in kind: voice is one agent alongside eligibility, prior authorization, and inbox triage.
As of 7 August 2026, four of the five publish no rate on their own site. Agentman publishes $10 per hour of call time. That asymmetry is the honest summary of this whole page.
What Prosper AI actually is
From their own site, checked 7 August 2026: "AI Voice Agents for Patient Access and RCM" that "handle both patient and payor phone calls, including scheduling, benefits, and patient billing."
What genuinely stands out:
- Specialty depth. Dedicated pages for cardiology, dermatology, ENT, gastroenterology, OB/GYN, ophthalmology, orthopedics, pain management, pediatrics, podiatry, primary care, and urology. Very few vendors in this category have done that work.
- 80-plus integrations and a published API documentation site.
- Both directions of the phone — patient calls and payer calls in one product.
If your problem is phone calls and your specialty is on that list, Prosper is a serious option. We would rather say that plainly than pretend otherwise.
What they don't publish
There is no pricing page on getprosper.ai. We checked /pricing on 7 August 2026 and it returns a 404.
Their own writing is direct about it. In their guide to voice AI systems for patient call automation, Prosper describes its own pricing as "Custom, based on volume and use case" and adds: "Pricing is not public, so early budgeting requires a sales conversation."
There is a wrinkle worth noticing on that same page. Prosper lists Retell AI at $0.07 per minute, Synthflow starting around $99/month, and CloudTalk at $19, $29, and $49 per tier — attributing those figures to G2 — while giving no number for itself. Every one of those is a fair thing to publish. It is simply easier to name other companies' rates than your own.
We are not claiming Prosper is expensive. We have no idea what they charge, which is exactly the point: neither will you until you have taken the call.
You will see third-party sites quoting per-provider figures for Prosper. Those are aggregator estimates, not Prosper's numbers, and we would not budget against them.
The alternatives, compared
Every row below reflects what each vendor publishes on its own site, checked 7 August 2026. Re-check before you rely on it; vendor pages change.
| Vendor | Who it targets | Publishes a rate? | Scope |
|---|---|---|---|
| Prosper AI | Practices and outpatient groups | No — "custom quote" | Patient and payer voice |
| Infinitus | Payers, pharma, large provider orgs | No — platform + usage fees, no figure | Payer voice, benefit verification |
| SuperDial | RCM companies, health systems, payers | No — "Book a Demo" | Payer operations across phone, portals, APIs, EDI |
| Assort Health | Practices, specialty groups, FQHCs | No — "Book a demo" | Patient voice, scheduling, intake |
| Agentman | Independent and specialty practices | Yes — $10/hour of call time | Voice plus eligibility, prior auth, inbox triage |
Infinitus
Their site describes "a safety-first healthcare voice AI platform that automates phone calls to patients, payors, and providers." They name Fortune 50 clients including Carelon, UnitedHealthcare, Humana, CVS, Cigna, and Aetna.
Their pricing page publishes no rate, describing "annual platform and license fees combined with usage (i.e. per task or minute) as well as a subscription model," with discounts tied to multi-year contracts and monthly minimums.
Choose them if you are a payer, a pharma manufacturer, or a large provider organization with the volume to justify an annual platform fee. Not if you are a five-physician practice — you are not who this is built for.
SuperDial
SuperDial calls itself "the enterprise AI platform for payer operations," deploying "voice-first agents that work across every payer interface—phone, portals, APIs, and EDI."
That multi-channel framing is the most interesting thing about them, and it is the same insight behind our own product: the phone is not always the right tool for the job. Primary CTA is "Book a Demo"; no rate published.
Choose them if you are an RCM company or health system automating payer outreach at scale. Not if you need patient-facing calls — their focus is payer operations.
Assort Health
Assort targets practices, specialty groups, health systems and FQHCs with patient-facing voice: scheduling, triage and routing, intake, insurance, fax and referral automation, and refills. Primary CTA is "Book a demo"; no rate published.
They sell annual contracts, and we have one first-hand data point. In a July 2026 reply to a sales inquiry we made, we were told a $75,000 annual minimum commitment was required before an initial call could be scheduled — and that the minimum reflected a floor of five providers, about $15,000 per provider per year.
The floor is the more useful half. A practice with fewer than five providers is not being quoted a high price there; it is outside what was on offer. That is the quote we received in our situation, not Assort's pricing policy — quotes vary by practice size, specialty, and site count.
Choose them if you want patient-facing voice for a specialty group and can clear the qualification step. We go into more detail, including what that minimum was counted in, in Assort Health alternatives.
Agentman
Ours, so read this row with the appropriate skepticism.
Voice is $10 for each hour of call time — pay-as-you-go, billed by the minute, no minimum and no monthly commitment — or $1,500/provider/month flat for unlimited calls. Published at /medman/pricing, no form.
The real difference is scope. Alongside voice we run eligibility at $0.50/check, prior authorization at $25/submission, and inbox triage at $225/provider/month — three workflows a voice-only agent cannot do at all.
That matters most on your second purchase, not your first. When eligibility and prior auth live in one system, a check that finds a plan needs authorization hands that straight to the PA workflow; when they live in two systems, a person retypes it. We wrote about which handoffs actually break — worth reading before you buy your first agent, whoever you buy it from.
Choose someone else if your problem is genuinely and only the phone, and a vendor on this list has deeper workflows for your specialty. We would rather you buy the right thing.
The question that actually decides this
Not "which voice agent is best." It is: how much of your staff's lost time is actually spent on the phone?
Walk the front desk for a week and count. If the answer is "most of it," buy a voice agent, and any vendor here may serve you well. But in most practices we have worked with, phone time is one of four or five sinks. The others:
- Eligibility verification, where the 2023 CAQH Index prices a single manual check at $7.97 to the provider — and an electronic X12 270/271 check costs a fraction of that, with nobody on hold
- Inbound faxes and portal messages that need reading and routing before anyone can act
- Prior authorization, which CMS's 2024 interoperability rule is pushing onto a fixed electronic timetable
- Denial follow-up, which is queue work rather than call work
A voice agent solves the visible problem, because the phone ringing is the thing everyone hears. Whether it solves the expensive one is a different question, and it deserves a week of counting before a purchase.
Using voice for routine eligibility is the specific mistake to avoid. Calling a payer to ask a question the 270/271 transaction answers electronically means paying for hold time to retrieve structured data. Use electronic checks for the routine majority and voice for what is genuinely left over.
How to evaluate any vendor here, including us
Four questions, asked identically of everyone on your list:
- Is hold time billed, or only connected time? On payer calls this is most of the cost.
- Is there a monthly minimum or annual platform fee on top of usage?
- What is the rate for a call that fails or dead-ends? Payer calls fail often.
- Is there a setup or onboarding fee?
The published rate matters far less than what the contract counts as billable. Our guide to verifying vendor claims covers the same test for automation percentages — and applies to our numbers too.
One piece of context on why evaluation is this hard: when we checked 338 healthcare vendors in August 2026, 83% of the sites we could read required a demo or contact form before showing the product. Prosper is not unusual here. It is the norm, and the norm is the problem.
Frequently Asked Questions
What are the main alternatives to Prosper AI?
The closest alternatives for healthcare voice automation are Infinitus, SuperDial, Assort Health, and Agentman. Infinitus and SuperDial are aimed at enterprise buyers — payers, pharma, RCM companies, and health systems. Assort Health and Prosper both target practices and specialty groups. Agentman differs in scope: voice is one agent among several back-office agents rather than the whole product. As of 7 August 2026, Agentman is the only one of the five that publishes a rate on its own site.
How much does Prosper AI cost?
Prosper does not publish pricing. There is no pricing page on getprosper.ai, and their own blog describes their model as usage-based with a custom quote, noting that pricing is not public so early budgeting requires a sales conversation. Third-party sites circulate per-provider estimates, but those are not Prosper's figures and should not be treated as a rate. To get a real number you have to enter their sales process — checked 7 August 2026.
Is Prosper AI a good choice?
For an outpatient group that wants deep specialty-specific voice workflows and has the procurement capacity to run a sales process, yes. Prosper publishes specialty-specific pages for cardiology, dermatology, orthopedics, pediatrics and about a dozen more, plus 80-plus integrations. If your problem is genuinely phone calls and your specialty is on their list, they are a serious option. The friction is that you cannot evaluate cost without a call.
What is the difference between a voice agent and a back-office agent?
A voice agent works the phone: answering patients, calling payers, scheduling, and following up. A back-office agent works the queues that never involve a phone call at all — electronic eligibility checks over the X12 270/271 standard, prior authorization submissions, inbound fax and portal message triage, and denial follow-up. Voice-only vendors handle the first category. Whether you need the second depends on where your staff time actually goes.
Should I use voice AI for eligibility verification?
Only for the part that electronic checks cannot answer. An electronic 270/271 eligibility check costs a fraction of a voice call because nobody waits on hold, and it handles most routine verifications. Voice is worth its cost for complex specialty benefits, carve-outs, and payers that will not respond electronically. A vendor that proposes calling payers by phone for routine eligibility is selling you an expensive answer to a cheap question.
Why do healthcare voice AI vendors not publish prices?
Partly for a real reason and partly for a commercial one. The real reason is that voice cost varies with hold time — a call that waits 20 minutes costs more to run than one answered in two — so a single number misleads. The commercial reason is that quote-gating allows per-customer pricing and requires a sales conversation before a buyer can compare options. In our August 2026 check of 338 healthcare vendors, 83% of the sites we could read gated the product behind a demo or contact form.
How should I compare healthcare voice AI vendors?
Ask each one the same four pricing questions: is hold time billed or only connected time, is there a monthly minimum or annual platform fee on top of usage, what happens to a call that fails or dead-ends, and is there a setup fee. Then ask what share of your staff's time is actually phone work. If most of the burden is faxes, portal messages, and eligibility queues, a voice agent solves the visible problem rather than the expensive one.
Where we stand
We publish our rates because we think you should be able to budget before you talk to anyone. $10 per hour of call time for voice, $0.50 per eligibility check, no demo required to see either.
If after counting a week of staff time the answer really is "it's the phone," go take Prosper's call — they may well be right for you. If the answer is "it's the phone and the fax queue and eligibility," that is the case we built for.
Either way, count first.
