what it does
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, uh and other fillers in one tap. Every change can be undone.
11 caption styles
Punch, Karaoke, Pill, Reveal, Minimal, Editorial, Bold, Highlight, Block, Shadow and Emoji pop. Change the look with one tap.
10 free 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 TikTok, Reels and Shorts put on top of your 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
Chinese and Japanese lines never break in the middle of a word.
