Study without chaos - a collaborative university workspace
What it does
Write notes together, share course materials, solve assignments, and study with an AI tutor in one free collaborative workspace.
Write notes together, share course materials, and solve assignments in the same live workspace. Everyone's work stays together, from the first lecture to the final hand-in. Start a shared set of lecture notes, divide up an assignment, or edit the same draft side by side. Everyone sees the latest version without passing files around. Keep lectures, readings, problem sets, and reference PDFs in the course workspace. Add something once and it is ready for the whole group. Work through difficult ideas with an AI tutor that can see the notes and materials you choose. Ask follow-ups, challenge an explanation, and trace answers back to the source. Invite your whole study group, work in the same…from graphite.so

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.
