Duxiang

Duxiang (独响) is an AI companionship app founded by Dengke Wang (王登科), a serial product builder previously known for the viral "哄哄模拟器" (Hōnghōng Simulator) . The product functions as an "AI friend circle" where users post content and receive comments and interactions from AI characters they create—by mid-2025, users had created 2 million such characters, half original and the rest drawn from media, family, or pets .

The app has grown largely through organic discovery on Xiaohongshu, reaching 600,000 users and 50,000 DAU by May 2025, then crossing 1 million registered users and 100,000 DAU by August 2025 with nearly a million Xiaohongshu collections . Jinqiu Fund invested a million-dollar round three months before Duxiang launched its first hardware product, the "Xiangmeng Huan" (响梦环)—a 29-yuan NFC wristband that binds to a single AI character for touch-based interaction .

Wang describes Duxiang's design priority as depth of emotional connection rather than real-time chat or edgy content, built around a seven-layer relationship system tracking familiarity, trust, emotional resonance, memory depth, and long-term companionship .
