Ordinary subtitles are a picture of text. You can read them, but you can't do anything with them.
FlexiLingo draws its own subtitle bar over the video: the original line and its translation together, with every word tappable. Meaning, pronunciation, and straight into a deck — while the video is still playing. Words you already know fade back so the new ones stand out.
Works on YouTube, BBC Audio, CBC Listen and Spotlight English.
