24 alternatives to Kachika – "Learning Japanese Through Life"
I'm both a Japanese learner and an indie developer. Throughout my journey of learning Japanese (currently living in Japan), I've deeply felt the challenge of memorizing words — learning them only to forget, wanting to speak but finding myself tongue-tied. Why I Made This As someone who relies heavily on visual memory, I understand the power of turning abstract concepts into visual forms. You know that feeling when you're walking around and spot something interesting — maybe a beautiful seasonal poster, a curious shop name, or even just a package design that catches your eye? Those little…

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'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…

Actually, it is yet another tool to learn a language through immersion (classic set of features, watch on youtube/netflix, read a website or book). It has a popup dictionary so you can click on a word and it will show the definition. Nothing new in that regard, except that it has been made with only Korean in mind and does not plan to extends to other languages. I was learning and still am learning Korean (now using my own tool to learn!). I initially made the tool for myself because none of the tools out there could correctly figure out what a word was in the text. And that's where the…

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:…

I had a successful startup exit five years ago (we got very lucky) but recently realized I'm most happy when building software products. I spend the last ~2 months building this as a fun way to get back into software development; and to find out what all the kids are up to these days. I am also a passionate life-long Japanese learner so this project was really fun. It's been nutz how different things are now with all the AI whatnot. This for sure would have taken me a year, without all the AI. I did not spend much time doing market analysis or any of that jazz. Mostly because I was…
