The full list

Own-domain citation is the share of 288 grounded answers that cited the tracked name's own domains (subdomains included). Citation share is of all 2,586 citations. Question 7 ("Abridge vs Microsoft Dragon Copilot") names Abridge and Microsoft Dragon Copilot, so those counts include up to 12 answers each that name them by design. Without it, Epic (175/276) and Oracle Health (141/276) stay first and second; Abridge falls from 75/288 (3rd) to 63/276 (5th) and Microsoft Dragon Copilot from 73/288 (5th) to 61/276 (6th).

How this study was measured

24 questions × 3 runs each × 4 AI engines = 288 answers + 66 Google searches · 65 AI Overviews

24 questions asked three times on each of ChatGPT, Claude, Gemini and Perplexity, measured November 6 to 7, 2026. United States, English; Google retrieval uses desktop results. Models: gpt-5-mini, claude-sonnet-5-5, gemini-3.6-flash only, sonar-pro. Google AI Overviews come from DataForSEO, not inferred chat answers. Appearance counts returned text, including ungrounded answers; citation rates use grounded answers. Longer overlapping names suppress shorter ones; First mention is the earliest eligible name order. Own-domain rates include declared domains and subdomains; shared parent scopes may count for multiple names and cannot be summed as unique citations.

Perplexitysonar-pro727272
Google AI OverviewsDataForSEO Google SERP (live, advanced)6665 shown65

Own-domain citations count a domain plus all its subdomains, with the same rule in every table.

Definitions

  • Appearance rate: answers naming the tracked name ÷ answers returned, with Wilson 95% intervals.
  • First mention: average order in which the tracked name first appears (1 = first).
  • Own-domain citation: grounded answers citing the tracked name's domains ÷ grounded answers.
  • Citation share: citations to the tracked name's domains ÷ all citations.

Limits

  • Only 38 tracked vendors are ranked; results are not an exhaustive market ranking.
  • Only the tracked vendors were scored. The untracked vendors named most often were MEDITECH (24 answers), Optum (17 answers) and Modern Health (15 answers).
  • 354 of 360 planned results were returned: 6 of 72 AI Overview lookups were excluded after three attempts because Google search retrieval failed or returned incomplete results. They are not counted as no-overview results.
  • 66 successful Google searches: 65 overviews shown; 1 without an overview. Failures are excluded, not scored as zero.
  • All returned chat answers had search sources.
  • Question 7 ("Abridge vs Microsoft Dragon Copilot") names Abridge and Microsoft Dragon Copilot, so those counts include up to 12 answers each that name them by design. Without it, Epic (175/276) and Oracle Health (141/276) stay first and second; Abridge falls from 75/288 (3rd) to 63/276 (5th) and Microsoft Dragon Copilot from 73/288 (5th) to 61/276 (6th).
  • Source types use Company / brand sites only for verified official sites; other unresolved sites are Other / unclassified.
  • Wilson 95% intervals are descriptive; overlapping leading intervals do not establish a sole leader. Measurements do not endorse medical, legal, financial or product claims.
  • Augmedix (Commure), Cerner (Oracle Health), Nuance DAX (Microsoft Dragon Copilot) and Vocera (Stryker) counted under the current names with former names as aliases. Best Buy sold Current Health back to a co-founder in June 2025. The index counts how often names appear and makes no medical or safety claim.
  • Google Shopping and unresolved google.com/goto links are excluded from cited sources; original URLs remain in the evidence.
  • Answers were collected through each engine's API using the model IDs listed in the methodology. The consumer ChatGPT, Claude, Gemini and Perplexity apps can answer differently.
