I've only tried character.ai and GPT-3 through venus and risu. Of the two, c.ai is better for roleplaying but GPT allows NSFW. Though there are a lot of things you can get away with on c.ai that you can't on GPT
Also, be polite, guy above me. Maybe his mother's dead or something, that's why he specifically wants a NSFW one. Because, uh...to bypass the deadness
