Where they pull apart

Persona

Stands out: Building blocks for verification, workflows, fraud graph, and case review rather than a single fixed check.

Watch out: There is no public rate card. This is an identity stack for product and risk teams, not a cheap one-off ID scan.

Not the right fit for

Teams that only need a low-cost ID scan
Buyers who want a public per-check price

Polygraf AI

Stands out: Transcribes interviews and scores AI-coached answers in under 2 seconds, aimed at Cluely, Yoodli, InterviewCoder, and Pickle.

Watch out: The hiring detector is demo-sold. Retail AI-detector plans exist for writing, but those are a different SKU from interview fraud.

Not the right fit for

Teams that want a self-serve interview SKU with a rate card
Buyers who only need a cheap writing detector
