for facial micro-expressions, eye movement, blink rate, and voice stress to generate a deception probability score. All processing runs locally in the browser, no video is ever uploaded to a server. Six biometric signals are combined into a TRUTH / UNCERTAIN / LIE verdict with a confidence rating, grounded in established behavioral science (Ekman's FACS, Eye Aspect Ratio blink detection). Built for investigators, lawyers, HR professionals, personal use

Could you build this?
No Accurate, real-time biometric deception detection via in-browser video requires cutting-edge computer vision models (micro-expression detection, rPPG pulse extraction from skin color shifts, gaze estimation) combined with complex signal processing.
What it would actually take: Building a functional version requires WebAssembly or WebGPU implementations of specialized lightweight neural nets for facial action unit coding (FACS), eye-tracking, and remote photoplethysmography (rPPG). Beyond client-side optimization, validating deception probability requires deep psychophysiological research and calibrated ground-truth datasets, as the underlying science itself is heavily contested.
