Field notes
The workflow ties narration to interaction: the agent supplies both the lines and the clicks, and StageMaster records the app in one take. Users can also record their own screen and add typed voiceover, then trim, zoom, add subtitles, or choose a background. The page lists 54 on-device voices and says the software requires macOS 15 or later on Apple Silicon.
