Hi HN, I’m Linn, the creator of ToolKuai (https://toolkuai.com). Like many of you, I’ve always been wary of "free" online file converters. Most of them are black boxes: you upload your private documents or images to a remote server, and you have no idea where that data ends up or how it’s being used to train models. I wanted to build a suite of tools (Video/Image compressor, OCR, AI Background Remover) that runs entirely in the browser. No files ever leave your machine. The Tech Stack To make this performant enough to rival server-side processing, I leaned heavily into modern…
- AFA free, browser-only PDF tools collection built with Kimi k2.5Feb 2026 · pdfuck.com · ▲5
Hi HN, I built a collection of 40+ PDF tools using Kimi k2.5 (with about $50 worth of credits) and a lot of “vibe coding”. The site: https://pdfuck.com (almost forgot I owned this domain ) What it does: 40+ PDF-related tools Completely free No downloads, everything runs in the browser All processing is done locally in your browser for better privacy It’s deployed on Cloudflare, so the running cost is basically close to zero. This started as a small experiment and slowly grew into a fairly complete PDF toolbox. I’d really appreciate feedback on performance, UX, and what tools you…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
