## What is Popline?

Pick a video. Get styled captions in seconds. Fix any word by tapping it on the video.

FAST
Popline writes, times and styles your captions as soon as you pick a clip. Lines break at natural pauses, so they're easy to read at speed.

EDIT RIGHT ON THE VIDEO
Tap a caption to change it. Split, merge, or move it a tenth of a second earlier or later. Find and replace across every line. Remove um and uh from your captions in one tap. Every change can be undone.

9 CAPTION STYLES
Punch, Reveal, Minimal, Editorial, Bold, Highlight, Block, Shadow and Emoji pop. Change the look with one tap.

10 FONTS
Anton, Bebas Neue, Poppins, Bangers and more. Pick one for every caption, or keep the style's own.

OUT OF THE WAY
Captions stay clear of the buttons that short-video apps put on top of a vertical video, and away from faces where there's room. If there isn't, Popline tells you and you drag them where you want.

ENGLISH, CHINESE, JAPANESE
English, Mandarin Chinese (shown in Simplified) and Japanese speech. Chinese and Japanese lines never break in the middle of a word.

NO WATERMARK
Export at full resolution to Photos, or save an SRT file.

PRIVATE
Speech recognition runs on your device and your video is never uploaded. No account needed.

Needs iOS 26 or later. iPhone and iPad.
