Make Shorts that keep viewers watching to the end
Shorts live or die on retention. captionrich adds word-by-word captions viewers can follow on mute, trims the pauses that lose them, and exports vertical, straight from your browser.
Retention
Word-by-word captions that hold attention
The Shorts feed autoplays on mute, so viewers decide from the text whether to stay. captionrich burns on captions timed to every word, keeping people reading, and watching, through the loop.
- Captions timed word by word, never a beat late
- Styles tuned for small screens and fast reading
- Highlight and emoji emphasis on the key words
Pacing
Trim the pauses the retention graph punishes
Every second of dead air shows up as a dip in your audience-retention curve. Remove silences and filler words in one pass, and let smart jump cuts pull the whole Short tight.
- Silence removal with light, medium, and aggressive presets
- Filler words flagged in the transcript, cut in a click
- Jump cuts that keep the energy up between sentences
Repurpose
Turn long videos into a stack of Shorts
Your long-form uploads are full of Shorts waiting to be cut. Smart Scenes splits a recording into clean, clip-sized blocks, and any moment you select in the transcript becomes its own Short.
- Smart Scenes structure long takes into clip-sized blocks
- Select a moment in the transcript and cut it as a clip
- Each clip opens in the full editor for captions and polish
