YoooClaw C·ONE is a credit-card-sized Chinese AI device that captures context from notifications, voice recordings, and user interactions without processing or summarizing the data, instead passing raw information to AI agents. Founded by Xiao Ruizhe in July 2025, the device launched in May 2026 on Douyin Mall at 599 RMB, focusing on being a 'careful mover' rather than a processor, with reviewers praising its month-long battery life and minimalist design.
