The article offers a detailed review of ByteDance's newly released technical preview version of Doubao Mobile Assistant, emphasizing its deep integration with the phone's Operating System, rather than being a standalone app. The author demonstrates through numerous real-life and work scenarios (such as file processing, cross-platform price comparison, information organization, social communication, etc.) how Doubao Assistant enables multi-application collaborative operations, intelligent recognition, and decision-making, greatly simplifying user operation processes and effectively addressing the pain points of information silos and tedious operations in mobile apps. The article specifically mentions the natural voice interaction method and global memory capability, which allows the AI Assistant to understand user intentions and provide personalized services like a personal secretary. Ultimately, the author believes that Doubao Mobile Assistant is beginning to realize Elon Musk's vision of 'future phones not needing apps.' It achieves this by 'flattening' all app capabilities into a result-oriented intelligent layer, redefining Human-Computer Interaction (HCI) and making phones truly 'thin' and efficient.
