Interview Guard vs Polygraf AI

Same facts, side by side: starting price, free tier, MCP, API and what each one is actually built for.

Starting price

Interview Guard

$100/mo 7 day free trial

  • Small teams that want a $100 monthly plan before a volume contract

Polygraf AI

Sales-quoted

AI security suite that also flags interview cheating from tools such as Cluely. Hiring detection is sales-quoted.

Where Polygraf AI fits

Where they pull apart

Interview Guard

Stands out: It looks for 100-plus AI helpers including ChatGPT, Cluely, and InterviewCoder, plus overlays, remote desktop, VMs, VPN location spoofing, deepfakes, and proxy input. Alerts fire during the interview. Setup is pitched as three minutes with no IT project.

Watch out: This is not the InterviewGuard.ai coding-session product. interviewguard.io is a candidate desktop app. Do not mix the two rate cards. Per-interview fees apply on top of the monthly plan.

Not the right fit for

  • Teams that will not ask candidates to install a desktop app
  • Very high-volume desks that want flat pricing with no per-interview fee

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
