PSL Scale is a free AI-powered facial attractiveness rating tool that scores faces on the 1-8 PSL scale across 8 scientifically-backed dimensions, including symmetry, proportions, sexual dimorphism, facial harmony, and skin quality. It uses a normal distribution where 4 is the true average, making it statistically stricter than casual 1-10 ratings.
