Sidekick™
The agentic interface
What it does
The next big interface for your Mac and the agentic layer for your entire organisation.
Sidekick is an AI agent for your Mac. It writes, organises files, opens apps and gets everyday tasks done — just ask in plain English.
An AI agent that acts across your apps, files and system. Ask in plain English. It fills in the invite and sends it. You never touch the calendar grid. The same forty fields you have typed a hundred times. It fills every one, so you stop losing hours to forms. Clear distractions from your browser, then group what is left by project, account, or research topic. Caches, duplicate photos, old installers, leftovers from apps you deleted years ago. Deleted only when you say so. Photos by subject, invoices by the date inside the PDF, MP3s by their tags. Point it at a video, pick a quality, and the finished MP4 lands in your Downloads folder — full-resolution picture and audio merged for you.…from sidekick-os.online

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.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

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…
