When buyers ask ChatGPT, Claude, and Gemini about customer support, Zendesk ranks #1 of 15, a Visibility Score of 78 in Customer Support (and appears in 3 categories of the index).
These rankings are measured from what the three models know from training, not a live web search. The live-web grounded surface is rolling out across the index. Methodology.
Zendesk owns Customer Support; everything else is secondary.
Where it wins. In Customer Support, Zendesk sits at rank 1 with an 89% mention rate and is the first pick 35% of the time, making it the closest thing to a default answer when AI models field buying questions in that category.
Where it loses. In ITSM the story inverts: a 0% first-pick rate and absence from enterprise-tier recommendations leave Zendesk treated as a small-team fallback while Jira Service Management and ServiceNow absorb the serious procurement conversations.

Zendesk claims Customer Support and the models back it: #1 of 15 there.
