OnPage was the only product ChatGPT and Gemini named in all 6 of 6 answers when we asked them to recommend on-call management software on 4 August 2026. Nothing else came close: the next four names, Opsgenie, PagerDuty, TaskCall, and Xurrent IMR, each landed in 4 of the 6 answers (67%), and every other product appeared in half the answers or fewer.
We put six buyer questions to ChatGPT and Gemini, gave each one a single live web search, and logged every product named and every source domain cited. Fifteen different products were named across the six answers, but only OnPage showed up in every one. So a buyer typing any single one of these six questions was guaranteed to see exactly one name in common, and that name was OnPage.
How the shortlist changed from question to question
The bare "best on-call management software" question returned 7 products, and three of them appeared in no other question: FireHydrant, Jira Service Management, and Rootly, each named in just 1 of the 6 answers overall. That first question leaned toward incident-response platforms, also pulling in Squadcast and Zenduty (each 2 of 6), neither of which showed up in the small-teams, affordable, or recommendations answers.
"Best free on-call management software" returned 8 products, the widest set of the six, and it introduced two names that surfaced nowhere else in the run: GoAlert and iLert, each named in 1 of 6 answers. The free framing swapped the incumbents' pitch for open-source and free-tier tools, listing GoAlert and iLert next to OnPage, Opsgenie, Hyperping, Squadcast, Zenduty, and AlertOps.
"Most affordable on-call management software" named six products and, tellingly, dropped both PagerDuty and Opsgenie completely. The affordable shortlist was Hyperping, Xurrent IMR, TaskCall, XMatters, OnPage, and AlertOps, a mid-market value cluster that overlaps heavily with the small-teams and recommendations answers but not with the premium incumbents at all.
The gap between framings is the whole story: the "best" shortlist and the "most affordable" shortlist shared exactly 1 product, OnPage. Change one adjective in front of the same category and, apart from OnPage, ChatGPT and Gemini handed back an almost entirely different set of vendors.
The three middle questions behaved almost identically to each other. "For small teams," "what should I use," and "recommendations" returned 6 to 7 products each and kept recycling the same core of OnPage, PagerDuty, Opsgenie, TaskCall, and Xurrent IMR. Xurrent IMR and TaskCall each reached 4 of 6 answers almost entirely through this stable middle plus the affordable question, never once appearing in the bare "best" or "best free" results.
Where the answers came from
Twelve source domains fed the six answers, and three of them fed all six: reddit.com, onpage.com, and rootly.com, each cited in 6 of 6 answers. The other nine domains ranged from taskcallapp.com (5 of 6) down to connecteam.com and pagerduty.com (1 of 6 each).
The one community source was reddit.com, cited in all 6 of 6 answers, with no Quora or Stack Overflow threads appearing anywhere in this run. Among review directories, only g2.com showed up, in 3 of 6 answers (the "best," "small teams," and "recommendations" questions), while Capterra, TrustRadius, and Gartner did not appear at all. The "free" and "affordable" questions pulled from vendor blogs and Reddit rather than any directory.
The key pattern is vendor-owned domains feeding the answers that name them. onpage.com was cited in 6 of 6 answers and OnPage was named in 6 of 6; xurrent.com fed 4 answers and Xurrent IMR was named in 4; taskcallapp.com fed 5 and TaskCall was named in 4; xmatters.com fed 4 and XMatters was named in 3. When an assistant retrieved a vendor's own comparison content, that vendor almost always ended up on the list.
Rootly is the exception that proves the rule. rootly.com tied for the most-cited domain at 6 of 6, yet Rootly the product was named in only 1 of 6 answers. Its roundup and comparison pages fed every answer and named its competitors more often than itself, so Rootly won the citation game as a publisher and lost it as a product.
PagerDuty ran the opposite play: pagerduty.com was cited in just 1 of 6 answers, but PagerDuty was still named in 4 of 6, carried by Reddit, G2, and rootly.com roundups on brand recognition alone. And atlassian.com, cited in 2 of 6, sits behind two separately named products, Opsgenie (4 of 6) and Jira Service Management (1 of 6); we count those as the two distinct names the assistants used, not one combined figure.
What this means if you sell on-call tooling
Being named in 4 of 6 answers or better tracked with being inside the citation set, not with market share. The 12 domains above decided who got recommended, so the practical target is presence in those exact places: the Reddit threads cited in all 6 answers, the roundup posts on rootly.com and hyperping.com, the G2 category page in 3 of 6, and your own retrievable comparison content.
OnPage's 6 of 6 is the clearest lesson: its own domain was in the citation set every single time, and publishing content the assistants can retrieve is something a vendor controls directly. Rootly's 1 of 6 as a product is the warning attached to it: feeding the answer is not the same as being named by it, and a roundup that lists your rivals is visibility work you are doing for them.
Where Glotier fits
Glotier does not sell on-call management software, so we are correctly absent from all 6 of these answers, and we would not fake our way into a category we do not serve. This page is a measurement, not a pitch for ourselves inside it.
What you just read is exactly what we run for a customer's own category: six buyer questions, the real assistants, every product and every source domain recorded, so you can see whether you are the OnPage of your market (named 6 of 6) or the Rootly (feeding answers that name someone else). The check is free, needs no account, and takes about a minute.

Share is the percentage of the six answers in which each product was named. Five more products were named once each (1 of 6, 17%): FireHydrant, GoAlert, iLert, Jira Service Management, and Rootly.
