South Korean AI app went viral for AI characters that can talk, react, and respond to camera context

https://reddit.com/link/1ue5o4i/video/ozv6sohrc69h1/player Instead of only texting AI characters, the app shows characters that can talk through voice, lip sync, react with facial expressions, and respond to camera context during the conversation. The demo suggests a shift from text-based character AI toward video-native AI characters, where the interaction feels closer to a live call than a chatbot. For ML developers, the interesting part is the underlying stack: vision, speech, memory, avatar animation, lip sync, and low-latency orchestration all have to work together in real time. The open question is whether this becomes the next interface for entertainment AI, or if latency and uncanny valley issues keep text chat dominant for now.
