Where Facial Geometry Meets Human Perception

Created in Leipzig, Germany — born from a passion for Media Informatics, mathematical aesthetics, and real-world self-improvement.

The Leipzig Journey

It started in a student apartment in Leipzig, in a Media Informatics lecture hall that was more about databases than faces. Deep inside the letmerate community, I ran the experiments myself — every method, every measurement, thousands of hours tracking aesthetics research. The pattern kept repeating: the faces people found striking shared the same hidden geometry. Not opinion — structure. Beauty had coordinates.

The Math Behind the Mesh

Underneath the skin, facial attractiveness is architecture: bone structure, ratios, and 478 spatial landmarks that exist whether or not anyone photographs them. The AI Math Engine measures that architecture against a calibrated PSL baseline — an unbiased, standard number. No generative guesswork, no averaged approximations. Just geometry, measured to the millimetre.

Why Human Perception Matters

But math isn't everything. Someone who deviates from perfect symmetry can still walk into a room and own it. The Human Perception Engine completes the picture: real ratings from people across ages, genders, and countries — a global read on human charm, not just facial ratios. Compare the two on your dashboard, and see where cold math and warm perception agree.
