Where they overlap
Both produce animated, word-by-word captions that look good in a feed. If your clip is already cut and you just need captions fast, Submagic does that one job cleanly.
Where FrameOS has the advantage
Submagic starts after you've already found and cut the clip. FrameOS does that upstream work: it takes a full-length recording, finds and ranks the strongest moments, reframes them to vertical with speaker tracking, and then captions them — so you're not manually choosing and cutting clips before captioning begins.

FAQ
Is FrameOS a Submagic alternative?

Does FrameOS do animated captions like Submagic?
Yes — animated, word-by-word captions that stay editable and burn in at export.
Which should I use?
If you start from long recordings, FrameOS handles the whole pipeline. If you only need captions on finished clips, Submagic is a focused option.
