RandoFont
Inevitably when starting a new web project I want to pick the perfect font. This is just a browser that shows Google Fonts, randomly, and lets me tag favorites. I built this years ago and just used AI to give it a minor facelift.
Rubiks Cube Solver
Speedcube is an open-source platform for speedcubers featuring a Rubik's Cube solver, competition timer, algorithm library, and AI-assisted cube recognition directly in the browser. Built with React, TypeScript, Rust, and Python, the project aims to become an all-in-one platform for cubers—from beginners to competitive solvers. http://github.com/williamisnotdefined/rubiks-cube-solver/
Reviving my 2001 college band with AI
25 years ago, I was approached to join a band called Fading Maize at Ripon College in Wisconsin. We did what we could with what we had. We recorded 3 albums over the next 3 years and played at as many bars and coffee shops as we could. We built a website with Microsoft Frontpage. Then we all went our separate ways, got married, had kids, focused on other things. Earlier this year I had the idea to approach the lead singer who wrote all of the lyrics and melodies to the stuff we played back then and wanted to "reimagine" everything in 2026 using AI. That's the project I want to share here! The site has a before/after player where you can flip between the original dorm-room recording and the 2026 version mid-song without losing your place, so you can hear exactly what changed. The original 2001 website is preserved and browsable at https://www.fadingmaize.com/2001, rough edges intact. On the AI question, since it's the elephant: the songs, lyrics, and arrangements are the original human work from 2001-2003. AI gets a bad rap and I can totally see why, but our case was different. We wrote the lyrics, we created the melodies, we played the parts, it just didn't sound as good as we heard it in our own heads. Being fully transparent about our use of AI, sticking tightly to our original lyrics and melodies, but making full use of AI to give us the studio, session players, and production budget we never had seemed like the right balance of concerns. I'm super proud of how it turned out and the transparency we've used along the way. Happy to discuss the audio pipeline, the site (Next.js), or what it's like to A/B your 20-year-old self!
I built a free app for New Yorkers to save money on groceries
I built this because I see that grocery savings are achievable in NYC. People usually just go to the store they're used to going to, and it's rarely worth the effort of combing through card cashback, weekly coupons, CPG rebates. Most people leave real money on the table by not stacking them, and even more don't even know that these deals are out there.... so I built a way to automate it. You can use it for free, no login, currently NYC-only with ~690 stores. I built it so that you just search whatever you want (use commas if you want to search multiple items). Or - use the AI tool to help shop for you. If you're curious, it's powered by a trained LLama model. Honest limitations are coverage and freshness. Id love some feedback on where the data looks wrong or is stale. Question for the room - what to prioritize if you're working with messy, multi-source retail/pricing data? Is freshness or coverage the top priority if you cant get a uniform response from every source? curious on what to prioritize here.

Ant
Hello HN! I'm the author of Ant, a JavaScript ecosystem built around a runtime with its own JavaScript engine. Ant also includes a package manager, the ants.land package registry, a platform for deploying and hosting applications, and Ant Desktop for building native desktop apps with web technologies, similar to Electron. The goal is for these pieces to work as one coherent platform while remaining compatible with the wider JavaScript ecosystem. It's still early, and I'd appreciate any feedback on the overall direction or what you'd like to see from an e2e alternative to the existing JavaScript stacks. P.S. I’ve shared Ant here before as a runtime; since then, it has grown into the broader ecosystem you see today.

Kurvengefahr
A few years ago I made a pen plotter attachment for Prusa MK4 (https://www.printables.com/model/827264-pen-plotter-attachme...) and at the time I didn't have a good way to turn artwork into G-code for it, and I put the project on ice for a while. I recently wanted to dabble in line art again and made a small browser app to make it easier. As agentic AI tools of 2026 are quite addictive, it rather quickly grew into something quite a bit more - an integrated browser CAD/CAM for pen plotters that covers everything from importing existing artwork, creating artwork from scratch, preparing for plotting and hardware integration. It includes some off-beat features like a Logo interpreter for turtle art and Graves RNN for handwriting synthesis and in addition to 3D printer pretending to be pen plotters it now also supports actual pen plotters based on EBB (AxiDraw) and GRBL firmwares through Web Serial. If you own an AxiDraw or a GRBL plotter, I'd very much appreciate it you gave it a try and give feedback. As I don't own those, I did all the testing with a hardware mock on STM32, so I am not sure how well it works attached to an actual plotter.
