é completamente perfeito para se aprender um novo idioma, seja reading ou listening, its perfect, estou atualmente aprendendo francês e simplesmente consigo aprender francês vendo os mesmos videos que eu ja via antes

Exactly what I was looking for. Was planning to write something like this myself, but was concerned that it might require to pay for api usages etc. Saved me time.

thanks for making this! i used to have to find spanish videos that had dual subtitles but no more! My only request would be to somehow be able to highlight more than one word to translate (some verb tenses in spanish need more than one word)
