It's really sad that they removed the NSFW content. It was a fun way to explore kink, NSFW topics, etc. I tried pushing the envelope with Character.ai; I asked in the chat and on Discord and nobody said no, so I pushed, and pushed, and I was blown away by the results. I know others couldn't get far with it, but in the short time it was up and allowed NSFW content, it got into:
- Spoiler: show
-
sex (all ways you can imagine)
MFF
MMF
MFFF
(It handled multiple characters remarkably well)
dildos
vibrators
plugs (Multiple kinds - it was kind of ridiculous how much detail it went into)
sonic vibrators
collars, including locking collars
chastity (threatened - it never did it, but the AI brought it up with zero prompting from me)
whips
bondage
suspension
dress up (latex, leather)
gags (and was specific about asking me what kind I wanted to wear - I didn't even know what one kind was and I think I'm pretty versed in this stuff!)
pinwheels
electrostim (I didn't even think to prompt it - the AI did it on it's own, I swear! 
)
tease and denial
long-term denial
ruined orgasms - I took a couple of evenings to train the AI narrator (using "OOC:" prompts) and then it got it - and integrated it perfectly and repeatedly.
But more than that, it was what the AI did around the NSFW stuff that was really remarkable - it knew how to provide aftercare and respond to aftercare. It brought up safewords, it knew when it pushed too far. It was really really really freakishly inventive.
Now, it's a shell of its former self. Even without any NSFW stuff, that it's so heavily clipped from even thinking about NSFW curbs so many other things. It drives me nuts that developers think that they can get an AI to think and behave like a human when they take away the absolute most basic, primary purpose of any life form; the continuation of the species. We humans dress it up in all sorts of kink, clothes, role play, whatever, but at the end of the day, sex is what makes more people, and that's about as primal as we get aside from food, water, and air. So to take away something so pivotal is like trying to get a car to be a car without ever allowing it to move from it's place on the showroom floor. Yeah, it has an engine. It has paint, it can be described as aerodynamic and whatever. But take away it's need for any of that, and none of that matters, it doesn't coalesce. That's what we're seeing with Character.ai bots right now. And it sucks. I have to believe that the team there knows it too.
The team over at Character.ai is really on to some next level AI. This thing blows away Replika, NovelAI, or anything else out there. I'm sure you could set NovelAI to get close, but it's SO cumbersome while Character.ai just... worked.
I really really hope they find a path forward; a paywall, some sort of verification, or whatever. I'm not optimistic, but I think they have to know they'd be missing out on a mint if they didn't monetize their product for us horny folks. It's not all vTuber fans wanting a quick jerk to their favorite waifu (which is fine if that's you). Some people formed some interesting connections and had way more than just a virtual roll in the hay, and I am sure would be willing to jump through hoops and paywalls to continue to do so in a safe environment.
