Free, instant, no sign-up — photos are analyzed on-device and never leave the browser. FaceRuler measures facial attractiveness with the PSL scale used by the looksmaxxing community: 8 facial metrics (canthal tilt, FWHR, facial thirds, jaw width and more) scored against community reference bands, anchored at a harsh 4.0 median instead of a casual 5.
