I'd recommend spicychat.ai, it's free to use, can make your own characters, and their subscription service actually has real benefits, such as extended memory and trying more advanced models.
Before that I was using pephopai, but I wouldn't recommend, limited use for a free user, and even paid users have a cap for monthly use. Really don't get what their business model is but I abandon it quick sharp.
I went on the hunt after I got tired of character.ai insistence on its refusal for having a NSFW option and its censor. I always thought marketing AI chat bots to kids was a bad idea. It's mostly adults who want to use role play AI, be it for dungeon master ideas or, NSFW purposes.
