Polygraf AI alternatives

4 tools our write-ups put next to Polygraf AI, with starting price, free tier, MCP and API side by side.

Polygraf AI from Sales-quoted API

The short answer

  • Persona : Identity verification if the risk is fake people, not coached answers. From Sales-quoted
  • Veriff : ID and biometric checks at a published per-check rate. From $0.80/check
  • HireVue : Enterprise video interview suite with its own integrity tools. From Enterprise
  • Spark Hire : One-way video interviews without a dedicated cheating detector. From $249/mo

Why people look past Polygraf AI

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

What we noted

  • Hiring SKU is sales-quoted
  • No self-serve checkout for interviews
  • Writing-detector prices are a different product

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

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

What each one does differently

Persona

Sales-quoted API

Why it comes up: Identity verification if the risk is fake people, not coached answers.

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.

Best for

  • Marketplaces and fintechs building KYC or KYB
  • Trust and safety teams fighting coordinated fraud
  • HR teams verifying workers at scale

Veriff

$0.80/check 15 day free trial API

Why it comes up: ID and biometric checks at a published per-check rate.

Stands out: Self-serve Essential, Plus, and Premium plans with published per-verification prices and a 15-day trial of Premium.

Watch out: Essential has a $49 monthly minimum, Plus $99, and Premium $209. PEP, sanctions, extra data fields, and 2-year retention cost extra per check.

Best for

  • Startups that want self-serve ID verification
  • Regulated teams that need hybrid specialist review
  • Product teams using a hosted verification flow

HireVue

Enterprise

Why it comes up: Enterprise video interview suite with its own integrity tools.

Stands out: Video interviews and validated assessments in one enterprise suite.

Watch out: No published price, and it is far heavier than a small team needs for async video.

Best for

  • Enterprise talent teams standardising video interviews
  • Teams that need assessments before an onsite
  • High-volume employers that cannot run live first rounds

4.5 on Capterra from 50 reviews

Spark Hire

$249/mo API

Why it comes up: One-way video interviews without a dedicated cheating detector.

Stands out: Unlimited video interviews at a public $249/month annual start, then a full ATS if you want sourcing and workflows in the same vendor.

Watch out: The ATS (Recruit Pro) starts at $335/month billed annually, not $249. AI resume review and notetaker hours are metered by ATS plan. No free trial is advertised.

Best for

  • TA teams replacing live first rounds with one-way video
  • SMBs that want video without an enterprise HireVue contract
  • Companies that may grow into Spark Hire's ATS
