FAQ
Smile analysis questions
What does the smile analysis measure?
It measures smile intensity, left–right smile symmetry, mouth-corner balance, and mouth openness from mouth landmarks in your photo. It is a photo-signal reading, not a verdict on you as a person.
What is smile intensity?
Intensity estimates how strongly your mouth reads as smiling based on opening and corner lift. Neutral, subtle, soft, open, and broad are presentation categories for this photo.
What does smile symmetry mean?
Smile symmetry compares how evenly the left and right sides of your mouth appear in this photo, including contour and corner lift.
Does a bigger smile get a better result?
No. Smile intensity describes how strongly the smile appears; a broader smile is not automatically better than a subtle one.
Why can my smile look different between photos?
Expression, camera angle, lighting, and partial face occlusion all change how a smile appears. Compare multiple photos for a clearer picture.
What photo works best?
Use a clear photo with your full mouth visible, even lighting, and minimal motion blur.
Is smile analysis the same as attractiveness?
No. This page focuses on smile presentation in one photo. Attractiveness pages combine multiple appearance and photo signals with different weights.
Is my photo private?
Yes. Analysis runs locally in your browser. Your photo is not uploaded for this smile analysis.
