Will add smile to photo results look fake?

Results are strongest on forward-facing portraits with a neutral mouth. Extreme grimaces are harder to convert into a believable smile.

Does the smile generator change the whole face?

The edit focuses on the mouth and smile expression while preserving identity and overall lighting.

Can I use AI Smile Filter on group photos?

Single-subject portraits are recommended. Group photos may produce uneven expression changes.
