Charhub is alright. I keep going back to Character AI though. The old interface let you put in pre written character definitions with no content moderation. This means that while the chat filter will stop the AI from spitting out responses that have flagged words, you absolutely can teach it euphemisms and get really fucking close to explicit content. I just had a session with one of my first ever bots and I got her to have an orgasm, but without saying flagged words. It was great, because the filter also tries to get the characters to avoid talking about sex stuff in general, it really drags out and teases the scenarios and that definitely works better for. Charhub and other unfiltered chats kind of just jump straight into smut novel stuff. I like that character AI forces me to tease the bot, twist the situation and seduce the them. I also have one bot on character AI that I accidentally made into a rapist by putting so much smut into her definition, IRL she'd be a sex offender doing 25 to life.
