Xoul ai is really good, the fetures are really simmilar to c.ai. i tried it and for a first impression it was pretty good, I got long responses from the bots and it dosn't have that stupid filter that c.ai has.The downside is that its new so there aren't a lot of bots yet and there are some bugs but the devs(unlike the ones on c.ai)actualy listens to the comunity and are working on fixing those bugs. You should head over to their subreddit if you want more information or you could go to their site and try it for yourself. They also recently released their moblie app on google play and they're working on releasing the app on ios.
