SubMagic captions video. StoryShort captions and creates it.
Both tools add animated word-by-word captions to your videos. Only one of them also writes the script, generates the visuals, narrates and publishes, all from a single prompt.
They solve overlapping but different problems
SubMagic is a single-purpose caption tool. StoryShort is captions + a full short-video generator on one account.

Drop in an existing clip you've already recorded or edited.
AI burns in captions
Word-level transcription, pick a style preset, export.
