Subadub

Subadub is a free Chrome extension made for language learners who watch Netflix in their target language and want subtitles they can actually study from. It is not a Vietnamese course, but it can fit into your routine if you learn through shows and transcripts.

Once installed, Subadub turns Netflix subtitles into selectable text so you can copy and paste lines into notes, flashcards, or a dictionary tool. It is especially handy if you like collecting example sentences from real dialogue instead of using pre-made lists.

It also lets you download the full subtitle track for a video as an SRT file for personal review, so you can study outside Netflix. For details and installation, start from the official Chrome Web Store listing or the project’s GitHub page.
