Linkify Subtitles is a Chrome add-on developed by unicornporated that enhances your Youtube viewing experience by providing dual subtitles in an overlay format. This innovative tool allows you to watch videos with subtitles in two languages simultaneously. By clicking on any foreign word, you can easily access a dictionary reference, making it convenient for language learners or those interested in understanding foreign content better.

Furthermore, Linkify Subtitles offers the option to activate "hints," which are contextual translations of foreign words displayed on top of them. This feature adds another layer of comprehension for viewers looking to grasp the meaning of unfamiliar terms while watching Youtube videos.
