Why Your Videos Need Subtitles
80% More Engagement
Videos with subtitles get significantly more views and watch time. Most social media is consumed on mute — subtitles keep viewers watching.

Subtitles make your content accessible to non-native speakers and the hearing impaired. Expand your audience without any extra effort.
Algorithm Boost
TikTok, Instagram, and YouTube algorithms favor captioned content. Subtitles signal quality content and improve discoverability.
