Is there a way to create an Anki deck or mine sentences from my computer?

As the title says, I'm using an extension that adds Japanese subtitles to Crunchyroll as a part of my immersion routine. Of course, I'm finding words I don't know left and right, and I'm creating an Anki deck with them. Is there a way to kind of automate this process? Can I create Anki decks on my PC? Is there an easier way to mine sentences?

Thanks in advance!
