I built the literal Duolingo Killer
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.
I built the literal Duolingo Killer launched on November 25, 2025 with 11 votes, #906 of 9,796 launches that month and more than 75% of that year's launches.
In plain words
This is a Japanese learning app that offers varied lessons drawn from anime content instead of repetitive exercises. It was built to address the monotony of traditional language learning platforms. The app is designed for learners seeking alternative methods to study Japanese through engaging animated examples and diverse lesson types.

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…
Anki/Duolingo-like app using educational YouTube videos2024 · platoedu.org · ▲289Hi HN, I watch A LOT of educational YouTube videos but wasn't forgetting a good chunk of the details because I was only really passively watching. So I made a tool that generates quiz questions/flashcards from YouTube videos, and uses spaced repetition like Anki or Duolingo to keep it in memory. Let me know if you find it cool/useful (or terrible ) or if you want to know a bit about the details!

- AFApp for learning how to write Japanese2012 · kanjibyhand.com. · ▲55
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…
A Japanese learning app focused on efficient vocab/grammar acquisition2022 · lessons.nihongo-app.com · ▲161Hey HN, it’s been 8 years since I posted on here about the launch of my Japanese dictionary app Nihongo [0] and I’m finally back with a new app: Nihongo Lessons! Think of Nihongo Lessons as the textbook to Nihongo’s dictionary. It’s an app for learning Japanese, specifically made for learners who are serious about becoming fluent, and want a guided set of content that will help them efficiently acquire vocabulary and grammar. The project came about when Adam Shapiro of Japanese Level Up (Jalup) [1] announced last April that he was shutting Jalup down. As a fan of Adam’s work I was bummed to…
Personalized Duolingo (kind of) for vocabulary building2025 · github.com · ▲161Hi! 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…
