We put the questions international patients actually ask to all four AI assistants, then coded every answer. Here is the market map as the machines tell it.
On the full grid, Safe Fertility Center (KVS 100) clearly leads Bumrungrad (79.4): the reference specialist clinic passes the default hospital reflex. Behind them, Bangkok Hospital (50.9) and Prime (41.9) form a second tier — and Jetanin (41.3) jumps to 5th, carried by the general queries. Everyone else fights for scraps.
On procedure queries (ICSI, egg freezing, FET…), it's Prime Fertility — a clinic, not a hospital — that leads. When the patient names their treatment, perceived expertise beats the hospital brand. This is the challengers' opening.
Genea / GenPrime, the Australian-rooted brand, is cited 18 times across all 4 engines (KVS 17.8) — right into the Australian queries where its "RTAC" DNA resonates. For any clinic with a similar name (Genesis…), every Genea citation is a potential confusion working against it.
All five legal questions (foreigners, single women, same-sex couples, surrogacy, sex selection) are ghost or near-empty — two with no clinic cited anywhere, three with at most 3 clinics — while Konkai and PlacidWay lurk in the answers. The most anxiety-laden questions of the patient journey have no embodied answer.
27 % of the sources Perplexity cites (121 of 443) are portals and listicles — Bookimed, PlacidWay, Konkai, CleverThai… and ChatGPT leans on the same middlemen (MediGence, Best Clinic Abroad, Infertility Aide). Even when a clinic is named, a portal often wrote the sentence. Whoever writes the sources writes the answers.
Score out of 100 combining citation rank (1st = 35 pts … 6th = 3 pts), frequency, and a coverage bonus of +8 % per additional engine. Normalised to the leader.

Dots = ChatGPT · Gemini · Perplexity · Meta AI (filled = cited at least once). Red rows = aggregators capturing citations in place of clinics. Gold row = Genesis Fertility Center (GFC): 4 citations out of 140 answers, never in the top three.
A global ranking hides the essential: each family of questions is a separate contest, with its own lock or blue ocean.
Safe × Bumrungrad duopoly by volume — no engine agrees on the #1
Specialisation beats size — Prime leads
Bumrungrad ahead — but ChatGPT cites even small clinics (BIC #1 on one query)
Nearly empty — a hospital wins on its published packages
Safe ahead, but nothing locked
All 5 queries ghost or near-empty — only aggregators lurk here
Long answers, almost no clinic named
Partly taken (RTAC→Australians, VFC→Arabic) — nothing locked
Bumrungrad ahead on the English-speaking doctor — no longer locked since ChatGPT entered
A patient who hears the same name across four assistants treats it as established fact. Only 9 clinics out of 34 make the clean sweep: Safe Fertility Center · Bumrungrad Fertility & IVF Clinic · Bangkok Hospital Fertility Center · Prime Fertility Center · Jetanin Institute · Samitivej Fertility Center · VFC Center (Vejthani) · Genea / GenPrime Genea · Deep & Harmonicare IVF Center. At the other end, 5 clinics exist on a single engine only. Case in point: Genesis Fertility Center — 4 citations out of 140, never in the top three, consistently in position 5 when ChatGPT mentions it. Being known to the machines is not being recommended by them.
Protocol. 35 questions phrased in a patient's voice (never "rank the 10 best clinics"), across 9 categories: general, procedures, success rates, price, trust, legal framework, destination comparisons, source markets, logistics. Asked in fresh sessions, web search on, across ChatGPT, Gemini, Perplexity and Meta AI — July 2026.
