The Mubert ecosystem
What is Fuse by Mubert?
Fuse is Mubert's AI editor for video: it scores short-form video with generated music and sound effects, ducks the audio under speech, and adds styled subtitles. Fuse and Cast share an engine and split by deliverable — Fuse makes short-form video, Cast finishes long-form episodes.
The split is by what you are making. If the output is a video — a TikTok, a Reel, a Short, a talking-head clip — Fuse is the tool. If the output is audio you want to sound like a finished episode, Cast is.
They share the parts that matter: the same generative music engine, the same automatic ducking, the same subtitle generation.
