hey I found this project december 23 and you just commented on another thing I posted "amazing one shot that" I will give you an invite if you want (because it also does that) check bio will add contact dets now...
it was posted to this site earlier about 20 days ago and front paged and hilariously about half the comments were shooting it down the top voted comment was even "this is the worst website ever" lol xD and they since invite only to manage abuse (its a very capable service and currently free)
It's capable of what you just mentioned, and it made the other site that one-shot you said was amazing for the one shot (literally cut and paste the comment into the prompt, then 2nd was "Good, now do it better")
