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!

RewriteBar▲138Hey HN, I wanted to share a tool that I've been working on called RewriteBar. It's designed to help improve your writing without the need for context switching. With RewriteBar, you can simply select a sentence, choose an action from the menu bar, and watch as the text is transformed. It works seamlessly in any macOS application and is powered by OpenAI. Some of the key features of RewriteBar include: - Correcting grammar errors that even Grammarly may have missed. - Rewriting your text in a different style to give it a fresh perspective. - Translating sentences quickly without the hassle of…

Hi HN, I watch A LOT of educational YouTube videos but wasn't forgetting a good chunk of the details because I was only really passively watching. So I made a tool that generates quiz questions/flashcards from YouTube videos, and uses spaced repetition like Anki or Duolingo to keep it in memory. Let me know if you find it cool/useful (or terrible ) or if you want to know a bit about the details!

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…

Hello Hacker News, When learning foreign languages, I made the most progress by speaking them throughout the day, every day.

Wordwise▲114Hey HN, While learning Danish, I kept translating the same words over and over. I’d take notes, highlight books, save things in random places… then lose track of it all. I wanted something simple. Translate a word, save it with context, and review it later so it actually sticks. Nothing I found really did that. So I built my own app. It lets you: - Translate and save words instantly - Add notes, tags, example sentences, gender, even emojis - Review everything with flashcards using spaced repetition - Track how many words you’ve really learned - Use it fully offline with on-device ML Kit…
