LocalPDF Kit
Every PDF tool you need. Zero uploads, ever.
What it does
LocalPDF Kit is a fully offline Windows desktop PDF toolkit. All 10 core tools (merge, split, compress, rotate, organize, protect/unlock, images↔PDF, watermark & page numbers, metadata) run 100% locally — your files never leave your PC. Unlike browser tools that upload everything, this is a real native app with one-time lifetime pricing (no subscription), no account, no usage caps, and an optional “Chat with PDF” that uses your own API key only if you want it. Privacy-first by design.

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.
