Products that do what App for learning how to write Japanese does
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…

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:…

Goal was to make it easy to jump from textbook learning into immersion. I wanted to play video games in Japanese, and started by using LLMs and a notebook, but figured it would be easier to streamline it all in an app. - You input a sentence in Japanese (easier on mobile where you can handwrite kanji you don't know) - App translates the sentence, explains the grammar, and gives you a list of flash cards - You choose some flash cards to save for studying later - You input a question about the explanation for more information - App explains some more and gives you more flash cards - Repeat And…

Hi HN, I have been studying languages as a hobby for a large portion of my life. Hence, I decided to create a spaced repetion app with the techniques that have helped me the most so far. It's aims to be made simple for the regular user to plug and play. I'd love to hear your feedback!

Over the last couple of months I have designed and written Keys, a Mac application the helps learning typing and that is supposed to meet Mac users standards for a well-designed application. My goal is to become a micro-ISV or indie developer. The app is only in the Mac app store for now (no trial yet), since end of May, and I have been busy putting together a website and a personal blog since. I would be very interested what the HN community thinks about the application, how you like it, and how it is presented, from a business angle. Prior to this project, I have done much more work on…

I’m specifically looking for a tool a user shared on here that facilitated writing for content by scrolling up and disappearing text as new text was inputted. I believe it was a HTML/JSS only solution - a small personal project. I’ve done a lot of focused searches, but haven’t been able to find this comment. That said, I love these sorts of projects. I know they’re a self-indulgence and often a distraction. I’m celebrating that for a moment, personally. Please share your favorites writing tools, the smaller and more personal the better.

Tl;dr: I built an alternative iOS/macOS app to Anki/Quizlet for learning vocabulary. You can write, collect and review example sentences with which you learn words more effectively than by just reviewing their definitions. A few years ago I wanted to improve my writing. As part of the learning process, I also wanted to expand my vocabulary. I’d highlight unknown words as I was reading books, and I’d saved them to flashcard apps. I’d reviewed them daily and for a long time I thought I was making good progress: during reviews, I’d usually guess correctly the meaning of words. My…

https://market.android.com/details?id=com.wtfsoftware.wtfgeneratorfunnypics I submit it as a proof that in 14 days anyone can become a (crappy) programmer :) I'm 32, educated in humanities, I work in a bookstore and in my entire life I have never tried programming. Just a typical user, I knew basic HTML, like adding bold to text etc. Few months ago I started lurking on hackernews, I read about CodeAcademy and decided to learn how to code JavaScript. Fast-forward 14 days: Wow, it's easier than I thought;) Here's my first app. It's written in Javascript and compiled in Appcelerator Titanium.…

I've been working for about 8 months on http://www.Learneroo.com, a site to teach programming and more through challenges. I created the site and all the content on it, and I'm looking for some feedback. Thanks!

Hi HN! In the last couple of weeks I've been working on Cranki: Cranki = Crosswords + Anki. (It's a stupid name tbh, haha) I like doing crosswords in Spanish (to learn vocab) but none of the apps out there allowed me to use my own list of words that I come across. So I built one instead. It's entirely client-side. No server, no database, no accounts, etc. Your words and stats are stored in local storage. I built this for myself but let me know if you like it!

I enjoy reading manga and journaling. Recently, I started wondering what would happen if I combined the two... I wanted a different way to document moments that happen in my life in a format that’s almost just as personal as writing, but also easy to share with friends. That’s how the idea to turn life memories into manga came about. With MangaMe, you can take moments from your life, anything from funny stories to the most mundane everyday activities, and turn them into a manga page for you to keep or share. The hardest part has been getting the AI to keep characters looking the same across…

I'm trying to get the motivation up to actually finish building out a "real" product, and I found myself needing a "win" to keep my momentum up. So, I hacked out a little one sentence journal app last night. I experimented with a few UI things (e.g.., the autosaving of the sentence for today and so on), so it was a good learning experience also. You can check it out at: http://osod.im

Hey HN! I created Hanasu.ai after my 9-5 job as a side project. Previously I'd used Duolingo to learn Japanese, but failed spectacularly when I actually spoke with my roommate from Tokyo. Now, after OpenAI improved their Realtime audio model in December and reduced pricing, I spent my entire winter break building. So how does it work? Just choose a daily topic and converse with the AI model: (1) Didn't catch a phrase? Double tap to reveal a transcript. (2) Couldn't understand? Double tap for translations powered by Google. (3) Can't recall that intricate Chinese/Japanese character? Just…

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
