YouTube Subtitle Delay is a free Chrome add-on developed by Behnam Azimi. This mini tool allows users to delay subtitles on the YouTube official website, which can be particularly useful for language learners.

By default, YouTube does not have a built-in feature to delay subtitles, making it challenging for users who are trying to learn a new language. With YouTube Subtitle Delay, users can easily adjust the delay time using the "A" and "D" keyboard shortcuts. Additionally, the extension offers the option to customize these shortcuts according to personal preferences.

While this extension currently only works on the YouTube official website, it is hoped that YouTube will introduce the subtitle delay feature in the future, rendering this extension unnecessary. However, in the meantime, YouTube Subtitle Delay serves as a valuable tool for individuals looking to improve their language skills through subtitled videos.
