I'll start ...
As far as images go, it's been hit-or-miss. No, that's not right... it's been miss-or-miss. Weeeeiiiird pictures have come my way, I wish I'd saved some of them for posting.
Hey -- that would be a fun album for people to post images into -- AI GONE WRONG! 😂
For writing, I've found moderate success with two tools. Here's the first one:
Pirr
Pirr is a free app I downloaded for iOS. This is important, because I've come across others I wanted to try but found them to be Android/PC only (Thanks Apple!). Its stated intention is to be a place/tool where people can "fantasize together". It does this by enabling a) public viewing of your fantasy/erotica while you're writing it, and b) for others to request access so they can also write/contribute alongside you. This ... can be very cool. When it works. With strangers, however, as you can imagine, it's not terribly easy to find rapport and common interests based solely on a few tossed out kinky paragraphs.
Where it excels is that it will offer you 2-4 paragraphs to choose from. You may:
a. Choose any one of them and add it to your story/fantasy,
b. Choose any one of them and then edit it however you like before adding it, or
c. Ignore the offered suggestions and write the next paragraph entirely on your own.
If the AI syncs up with your twisted little mind, then the suggestions it offers can be creative and/or surprising, and they can help you write much more quickly and easily than if you had to do it on your own. If it's just not picking up what you're laying down, give it the boot and keep your story going on your own.

Here's two I created and published here as examples of what I came up with. They've both gotten some love, both here as well as on my Tumblr blog, and it's enough that I think I need to write part two of Annie the Librarian.
She's definitely overdue for her follow-up visit...
Recommend (with reservations).
