I've been working on a little side project that combines Duolingo-like listening comprehension exercises with real content . Every video is transcribed to get much better transcripts than the closed captions. I filter on high quality transcripts, and afterwards a LLM selects only plausible segments for the exercises. This seems to work well for quality control and seems to be reliable enough for these short exercises. Would love your thoughts!

Hi! I'm living as an expat in France and I had a hard time following the news. So I've been working on Fluentsubs that turns YouTube content into a language learning experience. YouTube videos up to 20 minutes can be transcribed and listened to. At the same time I made it easy to lookup certain words and automatically add spaced repetition cards using the given context. This means that you can also rehearse with a real voice and not with AI dubs. This works especially well for the somewhat smaller languages that have a small track on Duolingo, and now are desperately looking for content…

Wordy▲231Hey HN, I'm Sándor. I built Wordy because I kept pausing Netflix to look up words in a dictionary. So I made a subtitle tool for myself, and it kind of snowballed from there. What it does: You watch short clips from real movies and TV shows, then get quizzed on the vocabulary you just heard. The app tracks every word automatically and adapts to your level. 20+ languages. How it evolved: Started as an iOS app for interactive streaming subtitles. Then I added curated video clips with quizzes. Then vocabulary tracking, spaced repetition, and personalized learning paths. Now it's iOS + Android +…

Hi! Wanted to share the project I really wanted to have. TLDR; this app lets you create your own list of words and you get a Duolingo-like experience (kind of, still needs a lot of features) practicing those words in their context. My English is not the best but not the worst either. But I realized I can't boost it up after a certain level! In my belief, in order to truly learn a language, you need to be exposed to that language often. Vocabulary is the key factor here if you really want to improve in any language. My experience is that when I read a book to improve my English vocabulary, I…
