That future isn’t far off. It’s already here. AI characters are transforming the way we connect with technology. These aren’t your standard chatbots that spit out canned replies. We’re talking about expressive, emotionally intelligent, voice-and-video-driven personas that can hold meaningful conversations, roleplay, or even headline your next YouTube short.
