One particular impressive feature is AI-assit smile - tried it with doubt but the outcome is so mind-blowing. It is the most realistic smile generator I've seen. Unlike Photoshop's lame "liquify" face-morphing feature, not only it updates the mouth shape, it also generates realistic wrinkles around your eyes, push your cheeks up etc etc to make the generated smile so good. You HAVE TO try it. I actually paid for the pro version just for this one feature alone.
Please add this to neural filter please please please can you imagine how many shots you can save just because of the subject doesn't know how to smile? (including my 5 year old girl)
