Introduction
In 2025, adding captions to your videos is no longer optional — it’s a must. With over 85% of videos on social media watched on mute, captions help grab attention, improve understanding, and make your content accessible to everyone, including people with hearing impairments.
The best part? You don’t have to type captions manually anymore. Thanks to AI and smart editing apps, you can automatically generate captions in seconds.
This article covers how to auto-caption your videos using free tools and apps for YouTube, TikTok, Instagram Reels, and more.
