SubDuo. Dual Subtitles for Netflix

About

SubDuo. Dual subtitles for Netflix in two languages at once

Ever watched a show with someone who speaks a different language? Or tried learning Spanish with Money Heist but kept missing half the plot?

SubDuo fixes that.

🎬 One line in the original. One line translated. Both on screen, in real time directly on your Netflix player. No pausing, no switching, no tab juggling.

Built for two people watching together: one of you speaks French, the other English, and you want to watch a Korean drama. With SubDuo, you each get subtitles in your own language, at the same time, on the same screen.

Dual subtitles are also one of the most effective ways to build vocabulary naturally and see the word in the original, see what it means in context, in real speech, without pausing.

How it works
1. Install SubDuo
2. Open Netflix
3. Pick your two languages
4. Press play
No setup, no account required to start.
