About

Rubi is a Safari extension that adds a second line of subtitles to videos you watch in Safari. It leaves the site's own subtitles untouched and adds one more language underneath. Listen in English while reading subtitles in both English and your own language at the same time. SUPPORTED SITES - YouTube - Netflix - Disney+ - Amazon Prime Video - TED - Udemy - Coursera GETTING STARTED 1. Open a supported site in Safari and tap "aA" in the address bar 2. Choose "Manage Extensions" and turn Rubi on 3. Tap Rubi in the same menu and choose "Always Allow" Open the app and these steps are shown with illustrations. You only set this up once. WHAT IT DOES - Shows a second language on top of the subtitles the service already displays - Drag the subtitle with your finger to place it wherever you like - Keeps showing while the video is in full screen WHO IT IS FOR - Language learners who want to check meaning without pausing - Anyone studying Korean, Spanish or another language through film and television - Listeners who only need help with the lines they missed Rubi does not stream or provide any video. Playback happens entirely in Safari, under your own account. The subtitles it shows come from the subtitle data each site already serves to you while you are signed in. Rubi does not store, export or share that data. A Netflix or Disney+ subscription is required for those services. YouTube works for free.
