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…

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.…

I've built mandoBot, a web app that segments and translates Mandarin Chinese text. This is a Django API (using Django-Ninja and PostgreSQL) and a NextJS front-end (with Typescript and Chakra). For a sample of what this app does, head to https://mandobot.netlify.app/?share_id=e8PZ8KFE5Y. This is my presentation of the first chapter of a classic story from the Republican era of Chinese fiction, Diary of a Madman by Lu Xun. Other chapters are located in the "Reading Room" section of the app. This app exists because reading Mandarin is very hard for learners (like me), since…

Hi HN! In trying to improve my Chinese skills, I built this tool that lets me write a mix of Chinese and English, then recommends a proper Chinese expression. This is super helpful when I want to write something in Chinese but I don't know all the vocab/grammar - I can enter my best effort and use English for the parts I don't know. Really, the fundamental benefit of the tool is that it encourages me to exercise the writing muscle, rather than defaulting to translating from English. My goal was to build something that is fast, relatively inexpensive, and not prone to misleading people.…

Hello HN, I built DuLink to solve a personal problem: my primary language is English, but my mother’s primary language is Mandarin Chinese. I often find articles on health or current events that I want to share with her, but the friction of copy/pasting and Google Translate meant she rarely read them. What it does: DuLink takes an article URL, extracts the core content to strip out clutter, and then generates a static, translated reading view. It preserves the semantic HTML structure (headers, lists) but removes the original site's JS and ad tracking. The "Why": Existing tools either…

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

I just started to learn frontend and built a free AI powered web app for editing text in image using AnyText. I will continue iterating the AnyText.pics to make it easier to use and will learn frontend skills by building the web app.

My co-founder and I built a Chinese language learning web app that helps you quickly master the most common Chinese characters and recognize 95% of real content. JinbuPal uniquely enhances learning for maximized progress by allowing effortless personalization of your daily study. When I dreamed up JinbuPal, I was a maker just like others in the HN community. I was working on my electronic hardware startup and I thought that learning the fundamentals of Chinese would help me communicate with manufacturers in Shenzhen. We designed JinbuPal to help you leverage data and your own curiosity to…
