Show HN: CrowdRank – live leaderboards for internet argumentshttps://crowdrank.appHi HN. I built CrowdRank, a small web app where people vote through head-to-head matchups and the results become a live leaderboard.Backstory:A few years ago, while I was learning to code, I wanted to build a Tinder-style voting app to rank the funniest characters from The Office. I hit a lot of dead ends, mostly on the frontend, and abandoned it.Now with a bit more technical background i rebuilt the idea as a more general platform. The backend/API is Laravel, and I used AI heavily to help build the frontend because somehow centering a div still finds ways to humble me.What did I end up building?A web based platform for ranking candidates inside different topics. There are no community-created topics yet. For now, I seeded a bunch of debates and used an Elo style ranking system, similar to chess ratings, to build a live leaderboard for each debate.No signup is needed to try it.A few example debates:- who’s actually funny in The Office? (of course)- programming language that sparks the May 14, 2026 11:19 AM

Show HN: Objo Studiohttps://objo.devObjo Studio is a new development environment for building desktop and command line apps. It has a visual designer, a debugger, a compiler, and a modern BASIC-like language called ObjoBasic. The aim is simple: make it enjoyable to build real applications for macOS, Windows and Linux and learn how to program.I've been working on Objo Studio in one shape or another since about 2019. I've always loved tools that let you move quickly from idea to working prototype and that abstract a lot of complexity and get out of your way. This has been tried before (VisualBasic, Xojo, etc) but have either been abandoned, become expensive or lost focus on hobbyists.The whole stack is written in C#. There's a custom stack-based VM that is roughly on-par with Python for speed but this is not a high performance tool. It's an all-in-one IDE for visually developing cross-platform desktop apps. It tries to make it simple for users, abstracting runtimes and libraries to help newcomers learn but also let them thMay 11, 2026 3:38 PM

Show HN: Mobile-ink, an open-source mobile infinite drawing canvashttps://github.com/mathnotes-app/mobile-inkHello everyone, I have been working on this for a year and it is such a difficult problem. mobile-ink is an open-source mobile infinite drawing canvas. There is not a strong open-source drawing engine beyond toy demos. Thus, mobile-ink aims to solve this problem and provide a state-of-the-art mobile note-taking canvas package.mobile-ink uses native Skia/Metal to address issues with native rendering, pencil latency, eraser behavior, page virtualization, preview caching, memory stability, page interactivity, etc. It has many advanced features such as shape-snapping, primitives to integrate figures, custom backgrounds, pdf import, stroke selection, smooth zoom/scroll, and more.The package is iOS + React Native as of now.May 8, 2026 5:01 PM

Ask HN: Is it a good idea to add a Design your download page?https://news.ycombinator.com/item?id=479196076 Months ago, I created a website called Openbeam.cloud which lets users to transfer files up to 100 GB of files including entire folders, but all the downloading pages were looking very white, I could easily add ad different theme or a good design, but I thought adding a special feature of design your own downloading page,My idea is to let designers or developers to show their work in more creative way1. Like a 2D artist will be able to give preview as background to client in the downloading page. 2. Game developer can add a background image or a gif and icons of the game they developed,I wanted will give more creative liberty to designers or creative guys.Would anyone use this?

Show HN: I built a toy that plays grandma's stories when my daughter hugs ithttps://www.storyfriend.co.uk/This was a project I built for my daughter's first birthday present.For context, I'm a surgical resident in the UK by background and am currently taking a year out of training to study a masters in computer science. My daughter just turned one. There are two things she really loves: the first is particular soft toy that she just can't live without, and the other is a good story book.Her grandparents live hours away and I didn't want her to forget what they sound like between visits. I wanted her to hear them whenever she missed them.My parents brought my brother and I up with incredible stories and books from all sorts of cultures, many of the stories being passed down from their parents before them. I didn't want my daughter to miss out on that.Finally, I was sick of missing storytime with her when I had to leave for night shifts. I wanted her to hear my voice before she slept every night.For all these reasons, I decided to build Storyfriend. It's her favourite soft toy with a custom Apr 24, 2026 12:06 AM

Show HN: Notation – an iOS chess coach (Stockfish on device and optional BYOK)https://notationchesscoach.appHi HN. Solo iOS middle aged, slightly burnt out dad from the UK here, wondering if anyone is interested in what I've been building. Lifelong chess fan, not very good but always trying to improve and I started to build Notation: Chess coach a while back. It's been live a month now on the App Store, doing modest numbers, and I've been learning a lot... mainly make my add brain slow down, stop, test everything twice and never when tired. Submissions will always wait another day!Many people play on chess com, or lichess, just as many in apps and OTB. What my app does (differently I hope) is bring that data together.You can import PGNs of your games, connect to chess com and lichess and sync your games over or play in the app. If you have a Chessnut electronic board, you can play IRL on that as well.Every game, every move is then analysed by a series of on device detectors, and classifiers. And I'm not talking about"I run Stockfish 18 and get your move evals" like most tools do.... Theres aApr 22, 2026 7:46 AM

Instead of writing my manuscript, I built a toolhttps://news.ycombinator.com/item?id=47849297Hi my name is Jeff, and I am a chronic procrastinator when it comes to my writing…Tell me that doesn’t sound familiar, I’ve literally written two blogs about this instead of actually writing my manuscript, cause literally anything (even scrubbing the toilet) is more compelling than the grind of getting through chapter 6.I actually started writing a tool in early January 2025. At the time, I was trying to find a way to gamify my writing. I wasn’t really looking to launch a serious writing tool at the time, just find a way to hack my brain into doing the work (and find another excuse to not write).The result of that was a simple text box with a word counter (0/500 words) that used a little bit of JavaScript to count the words you dumped in the box, deduct any shorter than 3 letters and then let you know if you hit your writing goal for the day (and you even got some fireworks!)The tool worked, I found myself anticipating pasting my daily writing progress into the box for that dopamine reApr 21, 2026 2:25 PM

Ask HN: Would you use revocable digital signatures to verify AI/Other content?https://news.ycombinator.com/item?id=47848539I’ve been exploring a potential product direction and wanted to sanity check it with people who actually build and ship things.Background: I’ve been working on a system using our core tech that can generate and verify digital signatures, but with a slightly different property than traditional approaches. The signatures are natively revocable. If the underlying model/system shouldn’t be trusted anymore, the signatures can be revoked either through a hard (delete the signing model) or soft (revoke the lease for the signing model) mechanism. I believe this feature is very beneficial on its own, but there are several other interesting properties (no key management, distributed verification, embedded metadata, etc.)Originally this came out of some deeper R&D work we’re doing, but I’ve been thinking this might actually be the most practical “wedge” into the market while we continue that research (and fund the research).One area that’s been interesting is applying this to AI systems.

Getting back into photography, ditching the phone camera in 2026?https://news.ycombinator.com/item?id=47842292I've been looking through twenty-five-odd years of my own photos. The collection includes scanned 35mm and medium format images; digital pictures from a few Canon Powershot generations and a 20D SLR; and about five iPhones.I've noticed that the non-cell-phone pictures tended to be better, and that in general I seemed to have quite a bit more fun with photos taken with, well, "real" cameras. Probably the best ones were taken with the 20D, which for its time was a really nice camera, for which I was able to bring over some lenses from my film days.I wouldn't rule out more film photography but I think of that as a somewhat separate track. I'd like to get a digital camera that captures a bit more of what I enjoyed about film photography - that high image density, looking through a physical viewfinder, not necessarily curating images in real time... looking, shooting, and moving on.I've been following Fujifilm cameras for awhile in this market, having read about them here a few years ago.

Show HN: Helm Terminal – Free portfolio intelligence that tells you what to dohttps://helmterminal.devHi HN,I'm the solo founder of Helm Terminal (helmterminal.dev). It's a free portfolio analytics tool that connects to your accounts via Plaid and surfaces actionable insights and intelligence. Concentration risk, tax-loss harvesting, earnings exposure, idle cash, sector drift, etc. Automatically, every day.Every other portfolio tracker/brokerage I've tried showed me balances and pie charts but never informed me what to do or what was going on. I'd check my accounts, see things were generally "fine", and move on. Then I realized I'd been sitting on thousands of dollars in unharvested tax losses, 60%+ of my portfolio was exposed to tech, and I didn't know half of my positions were reporting earnings soon.Helm is the tool I built to fix all of these issues, and a tool I wish existed. It runs on a set of intelligence engines on top of your connected accounts and gives you a prioritized inbox of things worth doing, as well as news tailored to your holdings worth looking at.
