Lexpresso - Turn YouTube & Netflix videos into vocab flashcards in 60s

Hey everyone! I'm Taisei, a Japanese developer learning English. I watch YouTube and Netflix in English. Whenever I came across a new word or expression, I'd add it to a spreadsheet with its meaning and an example sentence. But building that spreadsheet took longer than watching the video itself. I wanted to spend my time actually learning English, not making flashcards. So I built Lexpresso. You set your CEFR level range, click one button on any YouTube or Netflix video, and it extracts only the words that match your level — with definitions, paraphrases, translations, example sentences, and timestamps linking back to the exact moment in the video. It turns what used to be hours of spreadsheet work into a 60-second automated process. Free to try (3 decks, no credit card). Would love to hear what you think!
