That's where subtitle apps come in. These tools can take any video you make and turn it into something everyone can follow, no matter where they're watching from or how they're consuming the content.

Below, we’ve rounded up eight of the best subtitle apps to help you improve accessibility, boost retention, and make your content impossible to ignore.

What Is a Subtitle App?

A subtitle app is software that adds text to videos, displaying what's being said or described on screen. These apps use speech recognition technology to convert spoken words into text captions that appear on your video.

Modern subtitle apps do much more than basic captioning. They can add stylized text, animate words, translate languages, and even help you edit your video content based on the transcript.

How Do Subtitles Improve Video Engagement and Retention?

Adding subtitles to your videos can dramatically boost how many people watch and engage with your content. With 18.8% of people aged 18-24 reporting that they disable video sound, preferring captions instead, it's clear that subtitles are a significant engagement factor to be considered during content creation and editing. Here's why:

• Accessibility boost: Captions make your content available to deaf and hard-of-hearing viewers who represent 5% of the global population.
• Sound-off viewing: Most people scroll through social media with sound off, especially in public places.
• Better comprehension: Viewers retain more information when both hearing and reading content.
• SEO advantages: Search engines can index text from captions, helping your videos rank higher.

With 85% of videos watched on mute, captions aren't just nice to have; they're essential for reaching your audience.
