What is LiarLiar.ai?
LiarLiar.ai is an AI‑powered lie detection tool that monitors video feeds for heart rate variations, micro‑facial expressions, body language cues, voice pitch changes, language choice, and attentiveness. It uses remote photoplethysmography to capture subtle skin color changes linked to heartbeats, while computer vision analyzes micro‑movements and facial micro‑expressions.
The system runs in real‑time on popular video‑call platforms such as Zoom, Google Meet, Skype, Teams, and can also analyze recorded or YouTube videos. It transcribes conversations on the fly and provides an instant truth‑worthiness score, then records the session and generates a detailed report that includes heart‑rate data, body‑language metrics, and voice‑analysis results.
