Which applicant tracking systems do AI answer engines actually recommend?

When an SMB buyer asks an AI assistant which ATS to buy, a shortlist comes back. We asked 44 different phrasings of that question across 2 engines, 88 answers in total, and counted every product named. This is the result. Nobody paid to be on it, and no vendor list was written in advance — the 73 vendors below are simply everyone the engines named.

The leaderboard

“Answers” is how many of the 88 answers named that product. Share is the same number as a percentage. The two right-hand columns split it by engine.

Method

Every claim on this page is reproducible from the files linked at the bottom.

The engines

ChatGPT (gpt-5.5), Perplexity (sonar). Each was called through its public API with a near-empty system prompt — “answer the user's question directly and concisely” — and nothing else. The engines were not asked to produce a list, rank anything, or name vendors. Steering them toward a list would have manufactured the thing being measured.

The questions

44 distinct phrasings of one purchase decision, written before any measurement was run. No vendor name appears in any of them.

How the vendor list was built

Each of the 88 answers was read back and every named product extracted. The vendor list is discovered: a product appears here if and only if an engine named it. Counted are applicant tracking systems and HR/payroll suites whose recruiting module was named. Excluded, even when named: job boards, interview-scheduling and calendar tools, e-signature tools, skills-assessment and coding-test tools, background-check services, sourcing-only tools, and companies named only as an example employer.

Spelling variants of one product are folded together — “Workable”, “workable.com” and “Workable ATS” are one row, and a trailing “by company” is dropped. An edition name is folded into its product when the plain name is at least three times as common, so “LeverTRM” counts as Lever and “Workable Starter” counts as Workable. Two further pairs were merged by hand, and they are the only place a human judgement touches the list — it merges duplicates, it never adds or removes a vendor:

A product is counted once per answer, however many times that answer mentions it.

Is this stable, or is it noise?

The entire run was repeated a second time, same 44 questions, same engines, independent calls. The top ten came back 10/10 identical. Run B named 71 vendors over 88 answers against run A's 73. The tail moves; the head does not.

A leaderboard whose top ten reshuffles between runs would not be worth publishing, so this check was run before the page was, and the page ships only because it passed.

What this is not

This measures what two answer engines said on 2 August 2026, in response to these questions, through their APIs. It is not a quality ranking, not a review, and not advice on which ATS to buy. A product can be excellent and rank low here — that gap is the point.
