Other than the melting, hand weirdness and piss filter (ChatGPT), there's sadly none.
you can easily tell it's ai by the lineart. Ai cant replicate how an artist does lineart (line weight, overlapping lines) and it should stay that way.
But of course it differs from art style to art style but checking out the lineart is one way to find out its ai.
I don't use AI that much but since AI bs is promoted by ads everywhere you can definitely tell, faces look the same, those eyes and art style of semi 3d anime is very prominent of popular AI style and you can find it everywhere, even on video games, pron, now manhwa (were fukced), literally its like humans don't want to put any effort anymore especially since its porn like wtf its s3x bro is so low and use AI for EVERYTHING drawn in this (I bet some of the story is also written at least referrance to GPT if not all) at least the perverts we admire and love draw it real straight from their own mind and hands not this BS that is generated by AI
Is there a way to recognise ai like easily-- I'm not the type to give too much attention to details and I felt like this was easy enough to spot-- but mostly it's a gut feeling like 'oh, this feels a little... Off'
