You would like to watch a video, but you don't understand the spoken language and no subtitles were provided. There are volunteers that make subtitles for videos and upload them to the Comma Subs website. Every time you start watching a video on one of our supported websites this extension will check if anyone uploaded subtitles for that video so you can watch them. Currently supported sites are Berriz, YouTube and Weverse. NOTE: Automatic checking for subtitles is disabled by default. You have to click on the extension every time you want to know if there are subtitles available for a video. You can enable automatic checking for subtitles in the extension options.
