What is LiarLiar AI?

LiarLiar AI uses AI to detect deception by analyzing heart rate, body language, voice, and facial expressions. Powered by Remote Photoplethysmography (rPPG), it identifies subtle color changes in the face, micromovements, and other indicators of stress and dishonesty during video interactions. Compatible with Zoom, Google Meet, Skype, YouTube, and local video feeds, it offers a non-invasive way to monitor real-time cues. LiarLiar also includes transcription, reporting, and playback features.
