Subtitle Translator - hover a word in video subtitles to translate it, runs on-device in Chrome

I learn English from series with subtitles, and the loop of pause, open a translator, come back, lose the scene was killing it for me. So I built a Chrome extension for exactly that. It is free and needs no account. Hover a word in the subtitles and you see the translation. Click it and it is saved together with the full line it came from. Saved words get flashcards with spaced repetition, and you can export them to Anki, CSV, Excel or PDF. The part I like most: translation runs on-device

证据：I learn English from series with subtitles, and the loop of pause, open a translator, come back, lose the scene was killing it for me. ... Around 50 people use it now and I am trying to get to 100 with a zero budget.
