Sonilo - AI video soundtrack and sound effect generation platform, automatically analyzes visual rhythm

What is Sonilo

Sonilo is an AI video soundtrack and sound effect generation platform, founded by core team members from former ByteDance and Kunlun Wanwei Mureka . After users upload a video, the AI automatically analyzes the visual rhythm, emotion, and action, generating matching soundtracks and sound effects to form a complete sound system. Unlike Suno and other song creation tools, Sonilo focuses on the video workflow, requiring no additional description of music style from the user.
