Polygraf AI vs Verified Call: interview cheating detection
Polygraf listens to the answers. Verified Call also checks the camera, the video and the hidden tools on the candidate's computer. Polygraf AI judges the transcript for signs of AI coaching; Verified Call finds the tool itself.

Verified Call flags hidden AI tools like Cluely and Interview Coder, camera software, face swaps and a change of voice during live video calls, without a bot joining the call. It publishes its test results, including false alarms. In our own testing, each of 4 hidden AI tools (Interview Coder, OpenCluely, Pluely and Cheating Daddy) was found in 30 of 30 tries, with 0 of 30 false alarms with no AI tool open and 0 of 30 with everyday apps open (October 4, 2026).
This page compares the two on the questions hiring teams ask. Polygraf cells come from Polygraf's own press releases and from directories and trade press that quote its pages, with links. Checked October 2026.

Checked October 2026. Polygraf cells are its claims as published or quoted, linked in each row, not our tests. "No public information" means we found no public evidence, not that the feature is missing. Verified Call's results, with how each was tested, are on the Research page.
How Polygraf AI works
Polygraf AI's Interview Cheating AI Detector transcribes the candidate's answers in real time and checks the text for signs of AI coaching tools such as Cluely, Yoodli, InterviewCoder and Pickle. Its listing names speaker diarization, acoustic signature analysis, AI-text detection and VeXon. The result is a score and a flagged transcript with confidence ratings.
Polygraf says its interview module works in Zoom, Meet and Teams sessions. Polygraf describes no camera, video or face check for interviews. Polygraf describes no install for the candidate. Access to the interview detector is through a request form, and it publishes no price.
The transcript or the tool
Polygraf judges the transcript: it infers from the answers that an AI tool was coaching them. Verified Call finds the tool itself, on the candidate's computer, and checks the camera and the video as well.
A transcript can't show a face swap or a virtual camera. Verified Call checks both, before and during the call, with no bot in the meeting.
What the numbers measure
Polygraf's "99.9% accuracy" refers to transcription: words captured correctly. It says up to 98.7% detection of named tools and detection in under 2 seconds. It publishes no test method, sample or false-alarm rate.
Their 99.9% is how accurately they transcribe words. We publish every test, false alarms included: for example, 0 of 30 false alarms with no AI tool open (October 4, 2026, in our own testing). Why that number matters is in ask any tool for its false-alarm rate.
What Verified Call does
Verified Call checks the person on a video call, before and during it, without joining. The host turns it on for guests in Google Calendar. Verified Call checks for hidden AI tools, camera software and a change of face or voice. The host sees a badge next to each person in the call: Verified, Needs a look with the proof, or Can't confirm.
