Know when a candidate is answering with AI.
Diopter reads how a candidate responds, the answer pattern and the timing, and flags AI-assisted or coached answers in real time. You evaluate the person, not the model behind them.

Fake candidates are not interview cheating. They are getting hired, and paid.
Stolen identities, face-masked impostors, and AI-coached answers move through polished remote interviews and onto payroll. The question is no longer whether someone glanced off-screen. It is whether you are evaluating, and about to pay, the real person at all.
“The threat posed is both real and immediate. Thousands have been trained and deployed to blend into the global digital workforce and systematically target US companies.”
Others check if the video is fake. We confirm the candidate is real.
One AI-polished answer can read as good preparation. Scored against response timing, delivery, and identity signals across the whole interview, the pattern gives itself away.
Single-frame detectors
Deepfake checkers and interview-monitoring tools answer one narrow question at a time: is this clip fake, did the candidate glance away. Each check passes on its own, and the fake walks through.
Diopter reads the whole interview instead: who the applicant claims to be, what the live video and voice are doing, and how the person actually answers over time. Every signal is fused into one verdict on whether the candidate is who they claim to be. Not a pile of alerts. One decision.
- Applicant and email screen
- Live synthetic video and voice
- Answer pattern and response timing
Four gates. One verdict.
Every stage gets a read. The tripped gate is why the verdict says what it says.

Tripped at live interview: Answers resemble AI output in real time.
Point checks let a fake pass one gate at a time. Fused signals catch what each gate misses.
Four layers of protection in one recruiter workspace.
Everything runs inside the interview you already schedule. Nothing changes for the candidate.
AI-cheating detection
Evaluate the candidate, not the model feeding them answers. Diopter reads answer patterns, response latency, and timing against how real candidates talk, and flags AI-assisted or coached answers as they happen.
- AI-generated answers flagged in real time
- Timing and delivery scored against real candidates
- Preparation distinguished from live coaching
What happens when Diopter flags an interview.
From risk pattern to verdict to a clear next step, while the interview is still live.
Response latency irregular · answers resemble model output
A Risk Pattern Appears
Synthetic media, identity drift, or AI-assisted answers cross threshold during the interview.
Diopter Issues a Verdict
Verify, flag, review, or escalate: one composite call on the whole interview.
Diopter Recommends the Next Step
An explicit call routed to your team: proceed, take a second look, verify identity, or hold the offer.
Verdicts land where your team already works.
Interview verdicts, transcripts, and notes sync to your ATS and CRM, scoped with your team during onboarding.

Diopter's founders built QuillBot, the AI writing platform used by more than 35 million people. They know what it takes to ship AI that real users trust every day.

Our engineers build convincing real-time deepfakes as part of the work. The detection is built by people who know exactly what a fake candidate looks like on a live call.
What candidate fraud is costing you right now.
Every remote hire is a sanctions bet. Hire one North-Korean-linked or otherwise sanctioned worker and OFAC penalties apply whether you knew or not. Enter two numbers for a rough picture of the yearly cost.
$20K wasted interview time + $187K expected OFAC exposure
Every pay period a sanctioned worker is paid is a separate violation, up to the $377,700 statutory maximum each, with no cap on the total. About 10 pay periods on payroll is up to $3.8M for one hire, on strict liability you owe even if you never knew. Around 6.6 of your remote hires a year turn out fraudulent, and it takes one sanctioned worker among them.
Sanctions basis: Treasury, State, and FBI DPRK IT worker advisoryIllustrative estimate. Not financial, legal, or security advice.
See it run on your interview pipeline.
In 30 minutes we give you an overview of how Diopter works and how it fits the interview flow your team already runs, from screening through the live call. You will see where it catches synthetic candidates, deepfakes, and AI-assisted answers, with nothing to change about how you interview. Pick a time that works and we will send the invite.
- Built for talent and security teams hiring remote
- Works with Zoom, Google Meet, and Microsoft Teams
- Nothing for the candidate to install
The questions every talent team asks.
Diopter does not punish preparation. It distinguishes a person who prepared well from answers that are being generated or fed in real time, and it reports what it saw so your team makes the judgment call.
No single signal decides anything. Diopter fuses identity, media, and behavioral signals across the whole interview, and anything short of high confidence lands as a flag for human review, not an accusation.
No. Nothing changes for the candidate: no plugin, no install, no extra link. Diopter works on the recruiter's side of the interview you already scheduled on Zoom, Google Meet, or Microsoft Teams.
Zoom, Google Meet, and Microsoft Teams for live interviews, plus uploaded recordings.
Verdicts, transcripts, and notes are built to land in the tools you already use. ATS and CRM sync is scoped and rolled out with your team during onboarding.
