AI Auto-Subtitle Generator
Kapwing's auto-subtitle feature transcribes speech and generates timed subtitles with one click. The AI processes audio in 1-3 minutes for most video lengths and produces word-level timing for smooth caption display. Accuracy is strongest for clear English audio. The generated subtitles appear in an editable timeline below the video, where you can correct errors, adjust timing, split or merge caption blocks, and fine-tune word boundaries. The correction workflow is faster than typing subtitles from scratch — most videos need 5-15 minutes of review time after auto-generation.
