WHY ADD SUBTITLES TO REELS

MORE REACH

Most users scroll Instagram on mute. Subtitles retain attention — the algorithm sees watch time and shows the reel to more people.

HIGHER RETENTION

The karaoke effect guides the eye word by word — viewers stay focused and watch to the end. That's a direct signal to Instagram's algorithm.

PROFESSIONAL LOOK

Stylish animated captions make your content stand out among thousands of generic Reels. Five presets — from bold to minimal.
