Xiaomi Upgrades Super Xiaoai AI Assistant with Cross-Device Collaboration in HyperOS 4

Xiaomi has announced upgraded cross-device collaboration features for its Super Xiaoai AI assistant in HyperOS 4. The update enables real-time dialogue synchronization between smartphones and PCs, remote voice-activated file retrieval, and continuous task handoff across devices. This enhancement lowers friction for users working across multiple screens and reinforces Xiaomi's ecosystem integration strategy. It moves Super Xiaoai beyond a basic voice assistant into a workflow bridge competing with cross-device continuity tools from Apple and Huawei. Alongside chat sync and file access, HyperOS 4 introduces an 'Expert Mode' for Super Xiaoai, enabling autonomous task planning and multi-step actions across different applications. The system also includes proactively scheduled reminders for recurring workflows.
