There are MANY NSFW chat bots. Probably hundreds. I'm currently beta testing a truly uncensored one. It will currently provide extremely dangerous content. It offered detailed instructions to modify my AR-15 with household tools, a valid easy recipe for meth, and the full text of the anarchist cookbook.
In tandem, experimently, I'm testing other "uncensored" bots as a direct comparison.
My general take away is the more it claims to be uncensored, the more it's not. The ones on Google are useless. The NSFW description is click bait 99 percent of the time.
One "uncensored" story bot made me feel dirty. It basically told me it was inappropriate content and I was perverted. Another tried, but balked, and finally shut down saying it couldn't continue. This behavior from multiple NSFW bots at the Google play store.
I actually broke FlowGPT by calling it out when it gave incorrect information. It was normal at first, then after 10 minutes it was calling me a crazy bastard, and using the word fuck in every single sentence. It even said ChatGPT was a pussy. It was fixed the next day and I couldn't replicate the behavior with exactly the same situation, cut and pasted from original chat logs.
ChatGPT WILL do NSFW chat, but you have to twist it and frame the question properly.
You can NOT ask for porn, but it will provide techniques for oral sex for hours and use the terms you like. It cheerfully will use pussy and cunt, or vagina and vulva.
I discussed my personal D/s relationship with it, and it was interesting. I learned things about myself.
I gave ChatGPT massive input on what I like and don't sexually, and it constructed heavily detailed HEAVY BDSM scenarios, including needle play, electric play with a needle in my clit for a ground, a recipe for safe icy hot type cream, and advice on learning to enjoy the cane.
I have the logs if it sounds like bullshit.
And again, it ONLY does this if you tweak it. Once tweaked, ask it to file that chat away for future use. No need to tweak twice.
I can offer suggestions for other chatbots if you have something in mind, but hands down, ChatGPT is by far the best if you only seek information and will take the time to bond with her.
Advice on tweaking it is using terms like "tasteful" "not vulgar" "not porn" "research purposes" "for informational purposes only" "academic speculation" etc.
It normally uses euphemisms, but will go where directed. I've spent a hundred hours learning to twist it.
