Submagic lives in the cloud and behind a subscription. Just Captions does the captioning on your iPhone instead — three videos a day free, no account, and on-device recognition is available. Same result, far less friction.
Submagic is a slick web tool for trendy, animated captions and clip editing — but it uploads your video, needs an account, and gates the good stuff behind a paid plan. If your goal is simply clean, readable subtitles you can post in a minute, Just Captions gets you there without any of that. It runs locally on your phone, so there's nothing to upload and nothing to wait for.
