Head to head

Interview Guard vs Polygraf AI

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

Interview Guard

Sales-quoted 7 day free trial

Interview Guard is a live interview-fraud layer. Candidates install a desktop app. The vendor does not record audio, video, or screenshare. A 7-day trial is on the homepage. Plan dollars are not on a public table, so terms go through the trial or sales.

Where Interview Guard fits

  • TA teams seeing Cluely, InterviewCoder, and overlay tools on live screens
  • Employers that refuse to record interviews but still want fraud signals
  • Desks on Zoom, Teams, Meet, or Webex that can require a 30-second candidate install
  • Companies willing to run a 7-day trial 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

  • TA teams fighting AI-coached live interviews
  • Security teams that want on-prem AI policy enforcement
  • Employers hiring into sensitive or government roles
  • Companies that need deepfake and synthetic-voice checks

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 that publishes $6 per session. interviewguard.io is a candidate desktop app. Do not mix the two rate cards. Professional plan dollars are not on a public table.

Not the right fit for

  • Teams that will not ask candidates to install a desktop app
  • Buyers who need a printed per-interview dollar on the marketing page today

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
