DAG-based Kanji learning through components
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…

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…
- 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…

Learn Japanese contextually while browsingDec 2025 · lingoku.ai · ▲92Hi 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, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
