Sonilo – AI Video Music and Sound Effects Generation Platform with Automatic Visual Rhythm Analysis Operational

Sonilo is an AI video music and sound effects generation platform founded by core members of the former ByteDance and Kunlun Tech Mureka teams. After users upload a video, the AI automatically analyzes its visual rhythm, emotions, and actions to generate matching music and sound effects, creating a complete sound system. Unlike song creation tools such as Suno, Sonilo focuses on the video workflow and does not require users to additionally describe the music style.
