Zendesk leads this buying question by appearing in every single answer, but Comm100 and OneDesk press it hard on position.
Zendesk is the only brand that all three assistants recommended across all 12 answers, yet its average position of 4 keeps its slot score at 73, well short of dominance. Comm100 and OneDesk each score 65 and appear in 75% of answers at an average position of 3, meaning when they show up they tend to land higher than Zendesk does. Gemini is the most consistent source of OneDesk recommendations, citing it in all 4 of its answers, while ChatGPT mentioned it only once. The central reason the answers converge on these three is architectural: each is cited for offering signed Business Associate Agreements and built-in controls for handling protected health information, the non-negotiable threshold for healthcare buyers.

Slot score is position-weighted, 0 to 100: being recommended first counts far more than a trailing mention. "Appears in" is the share of answers naming the brand at all.
The main measurement above is the assistants' real answers with live web access. These rows show the same question on other surfaces: the models' bare memory, and Google's own AI search experiences.
ChatGPT, Perplexity, and Gemini each answered this question in two phrasings, several times each, with live web access and citations: the closest API-reachable version of the real assistant experience (no personalization or account memory, which no vendor can provide). Model-memory answers (no web) are measured separately and shown above as a comparison surface. A brand counts once per answer that recommends it. The exact questions:
