I actually stumbled upon one of those recently while browsing for new tech to try out. There's an app that's pretty popular which a lot of people seem to like, called golove gf ai. It's designed to provide not just text chat but also video and photo conversations, which is definitely a step up from older AI chat systems. You can literally generate and interact with an AI companion in various ways. It lets you create new chats and even explore different AI personalities, truly making the experience immersive. I saw that they often have promotions for their premium features too, if you want to explore more options like customized conversations.
