Face Symmetry Test is a free online tool designed to analyze and score facial symmetry. By allowing users to upload a front-facing, clear photo of their face, it uses artificial intelligence to evaluate key facial features such as eyes, eyebrows, nose, mouth, cheeks, and ears.

The evaluation checks for similar size, shape, placement, and orientation of these features on both left and right sides of the face. Based on these analyses, it generates symmetry scores for each facial feature and a combined score for overall facial symmetry.

The tool then categorizes the overall symmetry score into five levels, delineating 'Excellent Symmetry' to 'Distinct Asymmetry', which provides users with an intuitive understanding of their score.

It's important to note that this tool doesn't measure beauty or attractiveness, but rather, provides a quantified assessment of facial balance and symmetry.

Moreover, the AI takes into account that perfect symmetry is rare, and certain asymmetries can add uniqueness to individual facial features. Besides the symmetry analysis, this tool also educates users about different aspects of facial symmetry and its potential impact on face balance, expressions, and various facial features.
