One aspect.
Every aspect from one timeline.
Long-form and short-form.
Caption style
Different captions.
Different tools.
Submagic's strength is animated word-by-word designed captions. Sapari's is time-synced captions styled per aspect ratio. They look different on the timeline because they're for different jobs.
Bouncy. Designed. Per-word emphasis. Built for the scroll-stop on TikTok and Reels.
Time-synced. Styled per aspect ratio. Built to stay readable across 16:9, 9:16, and 1:1 — not to be the design.
If captions are the design — Submagic is still the deepest library on the market and Sapari isn't competing on that axis. If captions are a support layer that needs to look right at every aspect ratio without breaking sync, Sapari handles them as part of the pipeline.

Honest
Stay on Submagic if…
- → Designed captions are your creative signature — the bouncy animated word-by-word style.
- → Your output is exclusively short-form clips and the caption library is what hooks viewers.
- → Stock B-roll suggestions match how you produce content.
Submagic owns the designed-caption library. Sapari isn't trying to replace that. Word-by-word caption animation is on the roadmap, not shipping yet.
Before you ask
Common questions.
Can Sapari do animated captions like Submagic? +
Not yet. Word-by-word animated captions and floating-bubble effects are on the roadmap. Today Sapari styles captions (font, color, position, size, per aspect ratio) but doesn't animate per-word. If that's central to your creative, Submagic is still the better fit.
Does Sapari suggest stock B-roll? +
No. Sapari places B-roll you've uploaded. The AI director reads your transcript and matches your own assets to relevant moments. If stock library suggestions are central, Submagic covers that better.
Can I use both? +
Yes. Edit the source in Sapari (silence, retakes, audio, captions, B-roll) and run the 9:16 export through Submagic for designed animated captions. Some creators prefer that hybrid.
Does Submagic edit long-form? +
Not meaningfully. For a 45-minute recording with silence and false starts to cut, audio to normalize, and B-roll to place, Submagic isn't built for that shape of work — that's where Sapari fits.
