AURA — Facial Analysis for YouTube

AURA overlays real-time facial analysis on any YouTube video — 468 landmarks, FACS Action Units, expressions and microexpressions — running 100% on-device via Google MediaPipe. No uploads, no account, no tracking. It's honest about its limits: it is NOT a lie detector (facial deception detection is unreliable), so that part is clearly labeled non-diagnostic. Free, no ads.
