How to turn on subtitles on YouTube on your phone or computer, and set them to stay on automatically
YouTube can display subtitles — also known as closed captions — on videos uploaded to the platform to provide helpful written text alongside the audio.
Captions can be either auto-generated or provided by the user who uploaded the video, and turning captions on and off is a quick and easy process when you’re watching a video.
Here’s how to turn on those subtitles on YouTube, whether you’re on a computer or using the mobile app.
