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.
Upload your video
Drop in an existing clip you've already recorded or edited.
AI burns in captions
Word-level transcription, pick a style preset, export.
Download captioned MP4
That's the whole product — captions only.
You need to have already shot the video. Captions are the entire product.
Upload OR write a prompt
Add captions to an existing clip, OR generate a brand-new short from text.
AI captions or full pipeline
Same animated captions as SubMagic. Plus: script, AI visuals, voiceover, music.
Edit + publish
Refine in the editor, then download or publish straight to TikTok / YouTube / Reels.
Source footage optional. Caption what you have, or generate what you don't.

Because StoryShort generates, not just captions. Every clip below started from a text prompt.
