Word2go – A word-learning app using browser notifications

What it does

In the maker’s words, at launch

Hi Hacker News, I'm excited to share a project I've been working on: a web-based word learning app designed to help you effortlessly expand your vocabulary. If you're learning a new language, especially German, this might be just what you need. What is it? This is a straightforward web application that leverages…

  Personalized Duolingo (kind of) for vocabulary building2025 · github.com · ▲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…

  Hey 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…

  Learn Japanese contextually while browsingDec 2025 · lingoku.ai · ▲92

  Hi HN, Just wanted to share a tool i've been working on to help with my own study routine. It’s a browser extension called Lingoku. The idea is simple: we spend hours browsing the web in English every day. This tool replaces some of the english words with Japanese vocabulary based on your japanese level (Similar to Toucan, but with a better user experience). It’s basically an attempt to make the "i+1" method actually passive, you understand the sentence because it's mostly english, but you pick up Japanese words naturally from the context. It uses an LLM in the backend to make sure the…

  InstantDB – A Modern Firebase▲1,145

  Hey there HN! We’re Joe and Stopa, and today we’re open sourcing InstantDB, a client-side database that makes it easy to build real-time and collaborative apps like Notion and Figma. Building modern apps these days involves a lot of schleps. For a basic CRUD app you need to spin up servers, wire up endpoints, integrate auth, add permissions, and then marshal data from the backend to the frontend and back again. If you want to deliver a buttery smooth user experience, you’ll need to add optimistic updates and rollbacks. We do these steps over and over for every feature we build, which can…
