Face Shape AI is a lightweight, browser-based service that answers a simple but surprisingly useful question: what shape is my face? Rather than guessing in the mirror, you upload a single frontal photo and the tool runs facial landmark detection to locate eyes, nose, mouth and the outer contour of the face. From those measurements it derives the relative proportions of forehead, cheekbones and jaw, then classifies the result into one of six widely used categories.
The six shapes it reports — oblong, oval, square, round, heart-shaped and diamond — are the same categories stylists use when recommending haircuts, glasses frames, beards and makeup. The tool is completely free, works without registration, and is supported by advertising. The site states that uploaded photos are not stored permanently and are used only for the duration of the analysis.
The interface is in German and every result is accompanied by short explanations of the underlying shape so you can understand why the AI reached its conclusion. Accuracy depends heavily on photo quality: a well-lit, front-facing image with no hair or accessories covering the face produces the most reliable classification. It is designed for single-face photos, not group shots, and is best treated as a helpful orientation rather than a definitive professional assessment.
