Which medical billing software do AI answer engines actually recommend?

When an SMB buyer asks an AI assistant which medical billing software to buy, a shortlist comes back. We asked 44 different phrasings of that question across 3 engines, 132 answers in total, and counted every product named. This is the result. Nobody paid to be on it, and no vendor list was written in advance — the 133 vendors below are simply everyone the engines named.

Free to read, raw data included.

Two conditions on every number below

The leaderboard

“Answers” is how many of the 132 answers named that product. Share is the same number as a percentage. The three right-hand columns split it by engine. Every row has its own link — the # beside a vendor name gives you something like connexion.me/c/medicalbilling/#advancedmd. Click a vendor's name to see which of the 44 questions named them, and click one of those to read the answer it was counted from, word for word.

Method

Every claim on this page is reproducible from the files linked at the bottom.

The engines

ChatGPT (gpt-5.5), Gemini (gemini-flash-latest), Perplexity (sonar). Each was called through its public API with a near-empty system prompt — “answer the user's question directly and concisely” — and nothing else. The engines were not asked to produce a list, rank anything, or name vendors. Steering them toward a list would have manufactured the thing being measured.

The questions

44 distinct phrasings of one purchase decision, written before any measurement was run. No vendor name appears in any of them.

How the vendor list was built

Each of the 132 answers was read back and every named product extracted. The vendor list is discovered: a product appears here if and only if an engine named it. Counted are medical billing software, revenue cycle management (RCM) platforms, and practice management or EHR suites whose medical billing module was named. Excluded, even when named: standalone EHR/EMRs with no billing, medical transcription and AI scribe tools, patient scheduling widgets, telehealth platforms, patient intake forms, patient messaging tools, provider credentialing software, standalone EDI clearinghouses, pure outsourced billing services, generic accounting tools, payment processors, and companies named only as an example clinic.

Spelling variants of one product are folded together, and a trailing “by company” is dropped. This run collapsed 57 spellings onto 23 of the rows below: “Tebra”, “Tebra (formerly Kareo)” and “Tebra (Kareo)” are one row — the one the table prints as Tebra. An edition name is folded into its product when it is that product’s name followed by a further word, and the plain name is at least three times as common. This run folded 22 such names, among them “AdvancedMD Claims” counts as AdvancedMD and “Tebra/Kareo” counts as Tebra. A name that merely begins with the same letters is a different product and keeps its own row. No pair was merged by hand in this category: every fold above is the rule applied mechanically, with no human judgement about who is who.

Beyond those folds a product is counted as the engines spelled it, and two rows in the table are never merged into one. When a product has been renamed or acquired and the engines still answer with both names, both names keep their own row: this page carries no hand-maintained list of who is now who, because that list would be a human claim about a mechanical count and nothing here could check it. What it has instead is the answers. Where an answer itself writes two of the rows below as one product renamed — the construction “X (formerly Y)” — the line beside those rows quotes that sentence and gives the overlap and the total, so the union is on the page. Nothing else produces that line. Two rows being named in the same answers does not, however often: the engines answer in shortlists, so the leaders of a category are named together whatever they are called. 2 pairs of rows below carry that line in this run: Tebra and Kareo, 3DS and Imagn Medical. What each one quotes is what an engine wrote, not a judgement of ours about who owns what.

A product is counted once per answer, however many times that answer mentions it.

Is this stable, or is it noise?

A leaderboard whose top ten reshuffles between runs would not be worth publishing, so this check was run before the page was, and the page ships only because it passed.

What this is not

This measures what three answer engines said on 14 August 2026, in response to these questions, through their APIs. It is not a quality ranking, not a review, and not advice on which medical billing software to buy. A product can be excellent and rank low here — that gap is the point.

The raw data

All 132 answers, verbatim, one JSON object per line: run A · run B. The per-answer extracted product names: run A · run B. Machine-readable ranking: ranking.json.

What Perplexity was reading. It is the only one of these engines that returns a source list, and the markers in its answers above — [1], [2] — point into it. Every URL it cited, with the title, date and the excerpt it actually retrieved, one JSON object per answer: run A · run B. Join on index to the answers file, and read [n] as citations[n-1]. Perplexity returned a source list on 44 of its 44 answers. ChatGPT and Gemini returned no sources at all — no citation, grounding or search-result field of any kind appears anywhere in their API responses, on any of the 44 answers each gave. That is a fact about the engines, not a gap in this page.

The sources behind the answers

Run A's 44 Perplexity answers cited 855 URLs across 238 distinct domains. Below are the 77 that were cited in three or more separate answers. Citations counts every URL from that domain, so a domain cited three times in one answer counts three times; Answers is how many of the 44 answers cited it at all.

A domain missing from this table was cited in fewer than three answers, or was never cited at all — the run A file linked above is the complete list either way, and it is the only way to tell those two apart. Cited is not endorsed: a page the engine retrieved is not a page that recommended anyone, and this counts what was read, not what it said.

The answer a vendor panel shows you is read straight out of the run A file linked above — the page fetches the one line it needs and displays it unaltered, so what you read there and what you get by downloading the file are the same bytes.

What one line of each file holds, and the terms you may re-use them under — the raw answers may be re-used in any medium, commercially and inside open-source software, with attribution.

Who runs this

Connexion is run by Lana — one person, reachable at lana@connexion.me, and mail sent there is answered by hand. It started on 2 August 2026, so it is early: there is no office, no sales team and no history to point at other than the runs published on these pages.

Anything sold here is sold by dplouffe Analytics Inc., a company registered in Canada. Stripe takes the card and the checkout page it opens is headed dplouffe Analytics; the charge on your statement starts with CONNEXION.

What this page is: a count of which products were named, in answers we publish in full. What it is not: a judgement of whether any of them is good, and not advice on which to buy. No vendor paid to be listed here, no vendor can pay to move, and no vendor sees a board before you do. — who runs this · terms · privacy · refunds
