Good Chat Alternatives?

I use Grok only for role play and am curious if there are ant decent alternatives worth looking into. I like it because I can tell it who I want it to role play as(ex I can tell it “Role play as Max Verstappen during the 2026 season” and can tweak it however I want during the storyline but I don’t have to build his entire personality, appearance, etc) and I don’t have to build a bot or anything like that which is big for me, and it allows NSFW chat content(no images). I don’t have a computer and I’m not tech savvy, I use my phone so ideally I’d be looking for something I can just use on my phone(app/website). ChatGPT works great but it doesn’t allow NSFW chat content so that’s why I don’t really use it anymore. If it’s not a free platform then cost info would be great to know! I use the free versions of both Grok and ChatGPT. Grok has been the best I’ve found so far but after the latest update I’ve been hitting the limit faster(hit it today after just 3 messages) so I’m just curious on what else could be out there 😀
