About PolySub
PolySub is a Chrome extension that overlays live-translated dual subtitles on YouTube and any video site with captions — the original stays, your language joins it, so you never lose the voice of the person speaking. Live Transcribe adds captions when a video has none, while six free themes let each person choose a comfortable appearance.
