Top 50 Applicant Tracking Systems in AI Answers — August 2026

The leadership tier is dominated by three brands with near-identical momentum. Greenhouse (34.9%) and Workable (33.6%) remain separated by 1.3 percentage points, with Greenhouse commanding the strongest presence on ChatGPT (56.4%) and Grok (66.7%), though Workable performs comparably on Perplexity (35.9%) and ChatGPT (46.2%). Zoho Recruit (28.9%) holds steady in third place, showing particular strength on Google AI Overview (34.2%) and Perplexity (35.9%), and distinctly weaker presence on Google Gemini (25%) and Google AI Overview (13.2%), indicating inconsistent positioning across engines.

The next tier—Breezy HR (27.5%), Lever (22.8%), and JazzHR (22.1%)—forms a concentrated segment below the top three. Breezy HR peaks on Perplexity (38.5%) and Grok (38.5%) but drops to 10.5% on Google AI Overview, showing extreme engine volatility. Lever (22.8%) performs strongest on Grok (53.8%) and ChatGPT (41%), but falls to 10.5% on Google AI Overview, a 43-point spread. JazzHR (22.1%) shows consistent mid-range performance across engines, ranging from 5.3% on Google AI Overview to 38.5% on both ChatGPT and Grok.

Brands ranked 7 through 16 represent an established middle market with meaningful but secondary presence. iCIMS (16.8%), BambooHR (16.1%), BullhornStaffing (11.4%), Manatal (11.4%), Pinpoint (11.4%), SmartRecruiters (10.7%), Dover (8.7%), Workday (8.7%), ADP Workforce Now (6.0%), and Indeed Hire (6.0%) are named in 6–17% of answers. Within this group, Workday shows the widest engine divergence, named in 38.5% of Grok answers but appearing in only 0% of Google Gemini and 0% of Perplexity answers—a 38.5-point gap. iCIMS registers 0% on Google Gemini despite 35.9% on ChatGPT, suggesting inconsistent relevance signals across engines. ADP Workforce Now appears primarily on ChatGPT (20.5%) and barely registers elsewhere.

Positions 17 through 25 comprise a long tail of single-digit brands where presence becomes episodic. Freshteam, JuggleHire, Recruitee, and Gem each appear in 4.7–5.4% of answers, while Loxo, Jobvite, LinkedIn Recruiter, OpenCATS, and Recruit CRM all register at 2.7–3.4%. Gem shows the strongest citation rate at 9.4% from its own domain, yet achieves only 4.7% naming overall—suggesting engines cite Gem without typically recommending it. Lever, iCIMS, and Workable are the only brands in the top 25 with measurable own-domain citations (3.3%, 6.7%, and 5.8% respectively), indicating that brand visibility in answer engines does not correlate with engine-generated citations to vendor sites.

Positions 26 through 50 form a tail of near-invisible and entirely invisible brands. Jobsoid, Oracle Taleo, TFY, Brokerkit, and MightyRecruiter each register between 2.0% and 2.7%. Beamery, SeekOut, and ZipRecruiter appear in 0.7% of answers despite varying domain prominence. Paradox and Phenom each register 0% named, though Phenom appears in one Grok answer. A final cohort of 17 brands—CandidateHub, CareermInds, Copilot, Criteria, Easyrecruit, Fountain, Google Hire, Hirequest, Jazz, Keka, Manpower, Open, Recruiterbox, Silkroad, and Sourcing.ai—received zero mentions from any engine, despite being tracked. Fountain (2.1%) and Gem (9.4%) are the only brands in this entire tier with any own-domain citations, both appearing without corresponding naming rates.

The six engines divide into two distinct recommender profiles. ChatGPT and Grok name between 27 and 25 distinct brands respectively, with Grok showing extreme concentration: Greenhouse appears in 66.7% of Grok answers compared to 29.9% across other engines, and Grok's top three picks (Greenhouse, Breezy HR, Lever, Grok) account for 51.3% of all Grok answers. Claude, Perplexity, and Google AI Overview each name 24–25 distinct brands and show more balanced distribution, with the leader representing 30.8%–38.5% of answers. Google Gemini names only 20 brands—the narrowest field—with Zoho Recruit as the top recommendation at 25%. This divergence means the "consensus" brand list varies substantially by engine: Workable ranks second overall but appears in only 18.8% of Google Gemini answers, while Zoho Recruit (third overall) ranks highest on Google AI Overview (34.2%) and Google Gemini (25%).

Citation behavior shows inverse correlation with naming breadth. Grok returns zero citations to any source, despite naming 25 brands and concentrating heavily on Greenhouse. Perplexity cites at the highest rate (1.7% of answers cite a brand's own domain), followed by Google Gemini (0.8%), Google AI Overview and ChatGPT (both 0.6%), and Claude (0.3%). The citation data reveals that most engines default to third-party aggregators rather than vendor sites: Reddit (56 citations), People Managing People (49 citations), and Pinpoint HQ (47 citations) dominate the source list, while Greenhouse's own domain appears in only 21 citations—fewer than People Managing People despite Greenhouse's 34.9% naming rate. This pattern indicates that AI answer engines source recommendations from editorial reviews and community discussion rather than vendor-provided materials.
