    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…

    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:…

    Hey HN, After GPT-3 created waves in the tech industry, a lot of AI tools were emerging and with that, some AI website builders But the results seemed way too generic to us. It felt like the developers were rushing to catch the wave instead of building a proper tool We took our time, did months of RnD and finally came up with something better than what others in the market are doing. It’s got better design output. While it’s still in beta, I wanted to show HN what we did. Will appreciate the feedback when you guys try it out. Here is the link to signup for the beta:…

    orignally shared this on startup school... i thought id' share it here. i'm using a `nocode communication tool` (a web-based interface... a single browser tab!) for all of these things: 1. landing page — the landing page is the product and i wanted for folks to feel "transported" right into the app without having to walk through a shitty b2b marketing-style content. this is akin to my experience back in the `BBS` days of the mid-90's where you were immediately into the app, community, and tool. no terms of service, no privacy policy. just pure, immediate value. 2. building community — we…

    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!

    Try it at: ssh krnl.duetbrowser.com No sign up, totally free - no download. Let me know what you think. Prior art exists (brow.sh) but I wasn't satisfied with their graphical take. I wanted the raw, old skool terminal days of the early internet - BBS, and old green phosphor library comptuers - but running the modern web, with all the bells and jingle jangle whistles (JavaScript, etc). No funding, no VC, just 100% raw terminal fun. Not sure how long the demo will last, but try it out.

    After six months of work, I am here again presenting Fluent – a tiny lang which is optimized for differentiable & reactive programming. Since I am not Conal Elliot, don't expect a beautiful theoretical unification of FRP and AD from first principles. Rather, a horrific monster that holds together mostly because a lot of duct-tape. The link points to the semi-interactive tour of the language, which will get the job done much better than I could in here. Hope you hate/like it!

    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!
