Glossarie – a new, immersive way to learn a language▲363
Hi HN, For over two years I've been working on an App to learn languages (currently French, Italian and Spanish), together with my partner, a language teacher. I think it is finally ready to share with this community! The idea is to introduce vocabulary and grammar whilst you read eBooks in your own language. I've found that it is easier to remember vocabulary 'in context' and with regular repetition. Plus you don't have to carve out dedicated time for language learning. Other apps require you to build a habit around various exercises or ‘games’, whereas lots of people already read books.…

Personalized Duolingo (kind of) for vocabulary building▲161
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…

A Japanese learning app focused on efficient vocab/grammar acquisition▲161
Hey HN, it’s been 8 years since I posted on here about the launch of my Japanese dictionary app Nihongo [0] and I’m finally back with a new app: Nihongo Lessons! Think of Nihongo Lessons as the textbook to Nihongo’s dictionary. It’s an app for learning Japanese, specifically made for learners who are serious about becoming fluent, and want a guided set of content that will help them efficiently acquire vocabulary and grammar. The project came about when Adam Shapiro of Japanese Level Up (Jalup) [1] announced last April that he was shutting Jalup down. As a fan of Adam’s work I was bummed to…
