Products that do what Learning Chinese and Japanese with graphs and trees does
Just for fun, I built a language learning tool. It represents Chinese and Japanese as graphs of characters, with connections indicating given characters can form a word. It can also decompose characters to give clues on how they're pronounced, analyzes words to understand which ones are commonly used together, and more. It's fully interactive, supports offline use, generates flashcards, has sentences from humans and from AI, and plenty of other features. Check out the README for details. https://github.com/mreichhoff/HanziGraph

The idea is actually quite simple. As a Japanese learner and a coder, I've always wanted there to be an open-source, 100% free for learning Japanese, similar to Monkeytype in the typing community. Unfortunately, pretty much all language learning apps are closed-sourced and paid these days, and the ones that are free have unfortunately been abandoned. But of course, just creating yet another language learning app was not enough - there has to be a unique selling point. And then I thought to myself: why not make it crazy and do what no other language learning app ever did by adding a gazillion…

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…

Built this because tones are killing my spoken Mandarin and I can't reliably hear my own mistakes. It's a 9M Conformer-CTC model trained on ~300h (AISHELL + Primewords), quantized to INT8 (11 MB), runs 100% in-browser via ONNX Runtime Web. Grades per-syllable pronunciation + tones with Viterbi forced alignment. Try it here: https://simedw.com/projects/ear/

I'm a long time lurker that recently quit my job to work on my own projects, a lot due to the inspiration from Hacker News. Now I have published my first serious project, an app for learning how to write Japanese characters. It's the app I always wanted but couldn't find when I was studying. It tries to be simple to use, you just start the quiz and go with the flow. There's no need to plan and manage your studies, and it uses spaced repetition for better retention. There's a promo page with more details up at http://www.kanjibyhand.com. It's only for Android so far. The free version includes…

I've been fascinated by the Japanese language and culture for a while now, and I wanted to create a simple, no-fuss way for beginners to get started. So, I built *[Nihongo](https://nihongo.site/)*, a free and open-source web app designed to help you learn the fundamentals of Japanese in about a month. The name of the app, Nihongo (日本語), is the Japanese word for the "Japanese language." You can check it out here: *[https://nihongo.site/](https://nihongo.site/)* And for those who like to tinker, the code is available on GitHub:…

Hi Everyone, I recently wanted to learn Japanese with duolingo but it kept giving me repetitive lessons. So I built an app that gives a variety of lessons from anime. You can try it out here:https://kanjieight.vercel.app/ Thanks everyone.

Hey HN! I’m Alex, and one of my favorite ways to learn languages is by reading novels. Currently I’m reading 三体 (3 body problem), but one problem I've always had is it takes ages to look up words, and add them to Anki flashcards so I can remember them. 三体 is especially brutal with so much sci-fi vocab. That’s why I built Readly. I snap a pic of the page I’m reading, it loads the text in-app and lets me lookup words, add to Anki-style flashcards, or ask AI questions about the text, all in a single tap. It's a huge time saver. My specific learning strategy, if anyone wants to replicate it: 1.…

Hi HN I built this app while learning Japanese kanji after struggling to find a tool that showed how kanji are structurally connected through their graphical components. The core feature is a recursive DAG-style component graph (“Kanji Atlas”) that breaks kanji down layer by layer into radicals and graphemes, so you can visually explore how characters are constructed and related to one another. Demo at https://mykanji.app/components/kanji/鬱 I also built in a lot of my own opinions about how a learning tool should feel and work. Some features: 1. A kanji memory…
