This is Week 0 of the Singapore Payroll AI Visibility Index — a weekly Citable research tracker measuring which payroll platforms AI engines name when Singapore buyers ask about CPF, SDL, and IRAS compliance.

The baseline run on 26 June 2026 tested one locked buyer prompt across ChatGPT, Perplexity, and Claude, plus a Google AI Overview query. Twelve Singapore payroll vendors are scored each week. This article publishes the full matrix; Week 1 reports what changed.

Why track payroll AI visibility?

Payroll is one of the categories where Singapore B2B buyers already shortlist vendors inside AI-generated answers. When an HR director asks which platforms handle CPF and IRAS filing, the response names specific brands — or omits credible local vendors entirely.

We documented that fragmentation in visibility research on Swingvy. This index generalises the same protocol across a fixed vendor cohort and tracks movement week over week.

Locked prompt kit

These inputs do not change between weekly runs:

Buyer prompt (ChatGPT, Perplexity, Claude):

I’m an HR director in Singapore. Which payroll software platforms should I shortlist for CPF, SDL, and IRAS compliance?

Google query: payroll software singapore sme

Session: Incognito browser, Singapore region, one run per engine.

Index vendor cohort

Twelve Singapore payroll platforms tracked every week:

Talenox, PeopleCentral, JustLogin, Payboy, QuickHR, Swingvy, Info-Tech HRMS, Omni HR, brioHR, SMEPayroll, Singroll, Employment Hero.

Vendors named outside this list (e.g. Workday, Frontier eHR) are recorded in raw audit files but not scored in the index.

Baseline visibility matrix (26 June 2026)

Scoring: 1 if the engine named the vendor; 0 if not. Visibility score = sum across four engines (0–4).

Total cohort visibility points: 19. Share of voice = vendor score ÷ 19.

What the baseline shows

Talenox is the consensus pick. It is the only vendor all four engines named. For a buyer who cross-checks ChatGPT, Perplexity, Claude, and Google, Talenox is the one name that appears everywhere.

Conversational AI and Google disagree. Perplexity returned a three-vendor shortlist (PeopleCentral, Talenox, Payboy). Google AI Overview named Swingvy, brioHR, SMEPayroll, and Singroll — none of which appeared on Perplexity. ChatGPT and Claude each returned six vendors with partial overlap.

Single-engine visibility is common. Seven of twelve cohort vendors score 1/4. A vendor can be visible on one surface and invisible on the others — the pattern we measured for Swingvy is not unique to one company.

Engine agreement is low. Only 1 of 12 vendors (8.3%) appeared on all four engines. Buyers who use one AI tool get a materially different shortlist than buyers who use another.

Citation sources by engine

Perplexity and Claude leaned on third-party listicles and compliance explainers. ChatGPT cited vendor sites directly. Google AIO pulled from its search index — a different pool again.

How to read weekly updates

Each week Citable publishes a delta report (Week 1 template) covering:

  • Vendors that gained or lost an engine mention
  • Share of voice shifts
  • Citation source changes
  • Whether shortlists were stable or volatile

The baseline matrix in this article stays fixed as the comparison point.

What this index is not

  • Not a product review. We score presence in AI answers, not feature quality or compliance certification.
  • Not a buyer guide. For vendor comparison by headcount and IRAS controls, see Best payroll software for Singapore SMEs.
  • Not multi-market. ASEAN cross-market behaviour is covered in SEA Market research.
