Show HN: All-in-One Japanese Study Tool with AI + Anki I've been using AI a lot lately to help me study Japanese. I can pick up a bunch of words just from watching anime, but I'm still pretty weak when it comes to speaking and reading characters. I tried using ChatGPT to practice, but it quickly got annoying bouncing between different tools — I couldn’t chat and speak at the same time, and juggling stuff like Anki, dictionaries,etc. I built this as an all-in-one tool to do this in one place. Figured there are probably others in the sam…
Show HN: Browser-Use MCP for Claude that works without an API key Hey everyone, I built an MCP that enables the Claude desktop app to control your browser with Browser Use (YC W25). MCPs (based on the Model Context Protocol by Anthropic) enable Claude to use tools that can do a variety of functions like searching the web, executing code, manipulating files, accessing APIs; basically interacting with things outside the conversation context. The main reason I built this MCP was because I saw that existing Browser Use MCPs required me to get an A…

Show HN: A "Buy Me a Coffee" Button for Crypto Donations I am building a simple donation platform where creators can accept tips in crypto — kind of like “Buy Me a Coffee,” but Web3-native. No signups required for supporters. Just share your donation page and anyone can send MATIC, ETH, or any ERC-20 token directly to your wallet. It’s gas-efficient and built on Polygon. Each creator gets a customizable page with a short URL and optional message board. Everything is non-custodial — you own your keys and your funds. https://ift.tt/I2p…
Show HN: I created a ELI5 Blockchain glossary, with also a bit of interactivity The reason is simply that I'm learning blockchain and i found myself searching and hardly recalling terminology. So I started building a glossary (that slowly i'm making interactive) in which the terms are explained with ELI5 analogies. AI helped me with that. Hope you find it useful. You can contribute to the data set here: https://ift.tt/vLUxCzt https://ift.tt/7UPqOyA April 6, 2025 at 08:10PM
Show HN: A fast, minimal and offline-friendly web playground I built a web-based HTML/CSS/JS editor focused on speed, simplicity, and offline access. No bloat — just open and start coding. What makes it different: Live Preview – Edit HTML, CSS, and JS side-by-side with instant feedback. Offline support – Works without internet. You can even install it as a PWA and use it like a native app. No Login Required – Just visit, code, and preview. Login only if you want to save/share. Savable & Shareable Links – Save scripts in the cloud and get s…

Show HN: Windows XP Themed Personal Site Built with React I geek out on any UI from the 2000s, so I built my personal site to look and feel like Windows XP. Made this two years ago to get better at React. My goal was to fool my dad into thinking he was actually using Windows XP and it seemed to work. No mobile version (yet) :( If you think it's cool you can check out the somewhat outdated code: https://ift.tt/GQCedF0 https://ift.tt/pzj0IfN April 5, 2025 at 11:50PM
Show HN: I made an AI Platform that gamifies applying to jobs Hi there! I've created ApplyNinja, a platform that uses AI to help jobseekers apply to jobs faster and better. What differentiates ApplyNinja from the other "auto-apply" platforms is the trained AI model behind it. It learns from your resume and the jobs you apply to, and it provides better and better results. Currently, it serves as a helper for the entire application process: - Track & Monitor job applications - Generates Resume suggestions and highlights the par…

Show HN: DuckDB Powered SQL Editor Hi guys, I made an SQL editor that utilizes the duckDB engine to process your queries. As a result, the speed gains are +25% when compared to using any standard editor that connects through JDBC. I built this because I work on a small data team and we can't justify an OLAP database. Postgres is amazing but, if I try to run any extremely complex queries I get stuck waiting for several minutes to see the result. This makes it hard to iterate and get through any sort of analysis. That's when I got the id…
Show HN: A new VSCode extension that shows definition functions in a stack Definition Stack is a new vscode extension I have just released. It is a reading tool for Javascript and Typescript. It is available in the extension marketplace. You just click in a function in any source code, execute a command, and a new tab opens next to the original. That tab has a "block" which contains a copy of the function you clicked in. In that code every word (symbol) that has a definition is highlighted. If you click on a higlighted word a new blo…
Show HN: SPL – Multi-Language Pipelines and Your Own Mini-FaaS on One Machine Hello, Hackers! I’d like to share a pet project my teammate and I have been working on. The core idea is to build a multi-language computational graph that also lets you quickly deploy a mini-FaaS (Function as a Service) platform on your local machine. In other words, you can easily mix and match code from various sources (and even different third-party tools) using a local framework and server. We’re calling this project SPL. How did this idea come about? While work…

Show HN: Compare Cloud and Bare Metal Servers I built ServerSearcher ( https://ift.tt/Dv1HdMG ) to make it easier to find cloud/virtual and bare-metal servers that match specific requirements like RAM, location, or CPU. The idea came from my own frustration trying to compare cloud servers across dozens of provider websites. There are a lot of server marketplaces and hosts, but I couldn’t find a single place to search across all of them with proper filters. So I made one. ServerSearcher indexes servers from a few providers but I have only just …

Show HN: Instantly extract tribal knowledge embedded in any codebase Hi HN! GitSummarize is an open-source devtool that I made this weekend. Given any public GitHub repository it generates high-quality documentation from the codebase using Gemini 2.5 Pro. Specifically, it tries to extract the tribal knowledge, business logic/rules embedded within codebases. Pro Tip: You can replace "hub" with "summarize" in any repository URL to access its documentation. I created this because there was a steep learning curve to understandi…
