Show HN: Learn Languages When Watching Videos with Ease

I'd like to tell you about InterSub, a tool that I've been developing out of my pain of learning languages.

I found watching videos the best working option for me because it allows me to advance in language almost without spending extra time. I watch videos - series, TV shows, documentaries etc. not less an hour a day and switching on watching in the learned language gave me an extra hour of practice. I wasn't satisfied with solutions which I'd found on the market, and I decided to make a better one.

With InterSub, one can watch videos on your favorite platforms like YouTube, Netflix, Coursera and so on (soon), get instant translations of any unknown words or phrases in subtitles altogether with their context, have them automatically saved in a personal vocabulary and learn later in a fav mobile app. We designed InterSub to save one's time and energy, so a user can focus on mastering the language.

We'd love to hear your thoughts and feedback on how we can make the tool even better.
