Lie Detector 3000 is designed for police investigators, lawyers, security agencies, HR professionals, private detectives, and anyone who needs a fast, private, AI-powered deception analysis tool — combining facial micro-expression analysis with voice stress analysis for comprehensive results. The previous generation of our VSA system earned the trust of police departments and law enforcement agencies worldwide, as well as airports, investigators, journalists, corporate security teams and private clients. Building on that proven track record, our latest generation continues this tradition of reliability and innovation. We cannot disclose all client identities due to privacy and legal restrictions.

OVERVIEW
WHAT IS LIE DETECTOR 3000?
Lie Detector 3000 is an AI-powered biometric analysis tool that uses computer vision to analyze real physiological signals in video recordings. It measures eye movement, blink rate, facial micro-expressions, and stress indicators — the same signals studied by behavioral scientists and used by trained investigators worldwide.
This tool does not guess randomly. It performs genuine frame-by-frame facial analysis using a trained neural network model running entirely in your browser. Your video never leaves your device.
ANALYZED SIGNALS
WHAT GETS MEASURED
The AI analyzes five key biometric signals simultaneously throughout the entire video:
👁️
EYE BLINK RATE
Average blink rate increases significantly under cognitive stress and deception. Normal rate: 15–20 blinks/min. Stress can push this above 50 blinks/min.
↔️
EYE MOVEMENT
Rapid or evasive eye movement patterns are associated with mental effort and discomfort. Every frame is tracked for position shifts and velocity.
😰
NERVOUSNESS
Derived from surprise and fear expression scores. Elevated nervousness often indicates discomfort with the current topic being discussed.
😤
STRESS EXPRESSIONS
A weighted combination of fear, disgust, and anger micro-expressions — these surface involuntarily within milliseconds and are extremely difficult to fake.
🎭
EXPRESSION CHANGE
Tracks how rapidly and dramatically facial expressions shift throughout the video. High variance in expression is a known deception indicator.
🎙️
VOICE STRESS ANALYSIS
Micro-tremors and stress patterns in the voice are analyzed in real time. Involuntary vocal stress changes are among the most reliable deception indicators known to behavioral science.
📊
COMPOSITE SCORE
All six signals are weighted and combined into a single deception probability score that determines the final TRUTH, UNCERTAIN, or LIE verdict.
VERDICTS EXPLAINED
UNDERSTANDING THE RESULTS
TRUTH
Low stress indicators detected across all signals. The subject appears calm and relaxed. No significant deception markers found.
UNCERTAIN
Mixed signals detected. Some stress indicators present but not conclusive. Could indicate nervousness, discomfort, or partial deception.
LIE!
Elevated stress indicators detected across multiple signals simultaneously. High deception probability based on combined biometric analysis.
87%
The confidence score reflects how strongly and consistently the signals align with the verdict. A score above 80% indicates a clear, consistent pattern across all analyzed frames.
SCIENTIFIC BASIS
THE SCIENCE BEHIND IT
The signals analyzed by this tool are grounded in decades of peer-reviewed behavioral science research:
Paul Ekman's research on micro-expressions and the Facial Action Coding System (FACS) — foundational methodology used by the FBI and CIA
Blink rate as a cognitive load and stress indicator (Stern, Boyer & Schroeder, 1994)
Eye movement patterns and deception (Vrij, 2008 — "Detecting Lies and Deceit")
Machine learning facial expression recognition trained on thousands of labeled data samples
TensorFlow.js neural network infrastructure — the same technology used in commercial biometric applications
Eye Aspect Ratio (EAR) algorithm for real-time blink detection (Soukupová & Čech, 2016)
⚠ IMPRESSIVE NEW EXPERIMENTAL TECHNOLOGY · DECISION-SUPPORT TOOL
Lie Detector 3000 is an experimental AI-powered analysis tool. No AI system — and no deception detection technology in the world — operates with 100% accuracy. Even a conventional polygraph, used by law enforcement agencies worldwide, has a documented error rate of 15–40% and is not admissible as evidence in most courts.
This tool is designed as a decision-support instrument — to assist human judgment, not replace it. Results should always be interpreted in context and combined with other available information and professional assessment.
🔬
EXPERIMENTAL TECHNOLOGY
Based on real behavioral science but continuously evolving. Results are indicative, not definitive.
🧠
DECISION-SUPPORT TOOL
Use results as one input among many. Always combine with professional judgment and contextual information.
⚙️
CONTINUOUSLY IMPROVED
Our AI models and algorithms are regularly updated and improved. Subscribers always get the latest version automatically.
📊
POLYGRAPH COMPARISON
Even professional polygraphs used by law enforcement have a 15–40% error rate and are not court-admissible in most countries.

FAQ
FREQUENTLY ASKED QUESTIONS
Is my video uploaded to a server?
No. All processing happens entirely within your browser. Your video never leaves your device and is never transmitted to any server.
How accurate is the lie detector?
The tool measures real biometric signals with genuine AI analysis. Accuracy varies depending on video quality, lighting, and face angle. It should be treated as an analytical indicator, not a definitive verdict.
What video formats are supported?
MP4, MOV, WebM and most common video formats. For best results use a video where the face is clearly visible and well-lit, facing the camera.
Can someone fool the detector?
Trained individuals may suppress some signals. This is a fundamental limitation shared by all lie detection technologies including professional polygraph systems.
Is this the same technology used by professionals?
The underlying scientific principles and neural network architecture are the same as those used in professional behavioral analysis and academic research.
