Zendesk owns the enterprise customer support question, appearing in 100% of answers across all three models with a slot score of 90 — no other brand comes close.
Salesforce leads on position (average rank 1) but shows up in only 58% of answers and is heavily concentrated in Gemini, making its presence uneven rather than authoritative. ServiceNow appears in 67% of answers but sits at an average position of 4, meaning models cite it as a supporting option rather than a first recommendation. The owned slot status here matters practically: a challenger would need to close a 34-point score gap against a brand that every model, in every answer, treats as the reference point for this buying context.

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:
