Thank you Navid jan, It works in German Language and it is amazing. I have a suggestion: let us get sentence translation instead of word. please create a selection in setting to choose word or sentence.

This is absolutely insane and useful. Finding the meaning of that word while watching a movie is really difficult for me. Every day, I use it :)

Subturtle is amazing, I can now watch any series or movie on Netflix with the meaning of words, and another great thing is that it shows a very complete and clear explanation of the word you selected; And this makes you have more knowledge. Another problem that has been solved for me was watching YouTube tutorials, where sometimes I would miss the point of the tutorial, which is now done by the excellent Subturtle. I hope Subturtle gets added to Prime Video and Udemy. I look forward to seeing it.
