    Hey there HN - Today I'm sharing a demo of my our language learning tool, Phrasing. It's a tool born from the language acquisition hypothesis, too many hours in an anki slog, and a strange desire to always be learning obscure languages. The method is simple: 1. type in a show 2. learn the most important words 3. watch the show/acquire the words 4. review the words when needed in the future. On top of that, we're trying to: - do some novel things with spaced repetition (no more anki slog) - expand the sort of content you can learn from (I want to to refresh my French by reading The…

    Hello HN - Over the last few years, I've been building an app to learn languages. It supports ~85 languages and ~40 dialects, and is optimized for learning and maintaining multiple languages. Learning a language is a ton of work, but really quite simple. Find text you're interested in, dissect and understand it, and review it often. Grind that every day for a few years, and you'll be fluent. So I built Phrasing for 4 main reasons: 1. To have an app I would actually be excited to use every single day for years. 2.
