MiHoYo's AI companion interactive software "BSide: Olivia Lin" has launched a pre-release experience on the Steam platform, requiring a linked MiHoYo account and supporting Steam account association. Positioned as a tool application, it integrates AI interaction, music generation, and desktop dynamic wallpapers. The main character, "Lin Li," is a girl from Shanghai who majors in piano and minors in psychology. Users can upload MIDI files, and the system will automatically generate corresponding music videos. The application also includes AI-driven music creation, MIDI and audio generation, and text generation experiences. The character of Lin Li was foreshadowed; since August 28, 2025, the Bilibili account "Lin Li Olivia" had uploaded its first piano performance video, and in March of this year, it released video content about reading and responding to letters. Developers stated that this pre-release experience aims to collect user feedback to help optimize the product experience.
