Auto-captions are never right the first time. A name is misspelled, two lines are merged, the timing drifts by half a second — and most apps give you no way to fix any of it. Subvibe gives you the timeline. Tap a word to retype it. Drag a block to retime it. Split, merge, restyle — then translate the whole track into any of 20 languages and export it as a clean .srt file or burn it straight into the video. Your video never leaves your iPhone — only the audio is used to generate subtitles. Prefer full privacy? Switch speech recognition to on-device mode and work with no connection at all. • SUBTITLE EDITOR — retype, split, merge and restyle every line on the timeline • EXACT TIMING — drag blocks to fix drift and match speech frame by frame • TRANSLATE ON DEVICE — 20 languages, nothing uploaded, no account • AUTO SUBTITLES — accurate speech-to-text, in the cloud or right on your device • BEAUTIFUL STYLES — fonts, colors, outlines, backgrounds, and one-tap designer templates • ANIMATIONS — word-by-word reveal and highlight effects that pop on social • EXPORT YOUR WAY — save video with burned-in subtitles, or export an SRT file • ON-DEVICE MODE — switch speech recognition to your device and work fully offline Perfect for creators, editors, and anyone who wants clean, accurate subtitles without sending their videos to the cloud.
