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…

I was talking with a friend (@finnvoid) about how we could make it easier to practice their hiragana and katakana reading while they are living in Japan. After some quick basic idea-crafting with Gemini, they took it and ran with to, building "Jordle" a Wordle-esque tool to help them (and you) learn your furigana. Playing is easy, your goal is to transliterate the shown characters into the romaji (romanization). Pick between the two character sets (hiragana and katakana) or both to practice. Data is local to the device, so it's pretty snappy and technically works offline. We'll probably be…

Since I was young, I've loved anime, and over the years, manga has brought me joy, given me courage, and sparked excitement in my heart. However, as I read more, I realized that many of these manga weren't translated at all. I also came across some AI-based translation tools, but the results often fell short. So, I decided to create a tool that allows manga fans to read and enjoy their favorite manga, no matter the language or whether a translation team is available. This product has just been launched, and there are certainly areas that can be improved. However, with time, I'm confident it…
