SubDuo shows two subtitle languages at once on Prime Video, YouTube, Netflix and Disney+ — the original on top, your language below. No more pausing to switch subtitle tracks. Drag the lines anywhere on the video, scroll to resize each one independently, and set color and opacity per line so they never fight the picture. Settings save per site and sync across your Chrome devices. YouTube auto-generated captions work too. 12 languages. Free, no sign-up, 100% local — nothing leaves your browser.
