    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 spent a few hours last weekend testing whether AI can replace code by executing directly. Built a contact manager where every HTTP request goes to an LLM with three tools: database (SQLite), webResponse (HTML/JSON/JS), and updateMemory (feedback). No routes, no controllers, no business logic. The AI designs schemas on first request, generates UIs from paths alone, and evolves based on natural language feedback. It works—forms submit, data persists, APIs return JSON—but it's catastrophically slow (30-60s per request), absurdly expensive ($0.05/request), and has zero UI…

    Hey HN, I made Browser-Use, an open-source tool that lets (all Langchain supported) LLMs execute tasks directly in the browser just with function calling. It allows you to build agents that interact with web elements using natural language prompts. We created a layer that simplifies website interaction for LLMs by extracting xPaths and interactive elements like buttons and input fields (and other fancy things). This enables you to design custom web automation and scraping functions without manual inspection through DevTools. Hasn't this been done a lot of times? Good question, as a general…

    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…

    Hello! I finished school recently, and I've spent my time working on Nuenki (https://nuenki.app). It's a browser extension that translates sentences at your difficulty level into your target language and lets you quickly compare to the original by hovering. You naturally pick up the language as you browse, checking the original when needed. Translations are handled by DeepL, which is 3-6x more accurate than Google Translate[0]. You can use it for free for 24h, no card details required. I'd really appreciate feedback! [0] https://www.deepl.com/en/whydeepl

    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 spent some time to build an NPM package about state management (another one, I know) for Next.js/React.js. Idea: Storing web application state in URL, It's a bright idea to use URI, but there isn't a simple and good implementation. Can save state of forms, or filters, users can reload page or share the link. Demo to play around: https://state-in-url-asmyshlyaev177.vercel.app/ What I wanted to achieve and why The World need another library: - Storing complex objects, e.g. any valid JSON with nested fields. - Focus on Developer Experience and simplicity, API similar to…
