SignalUp

What it does

Your buyers ask ChatGPT, Gemini and Perplexity who to buy from. When the answer is your rival, you lose deals you never even saw. SignalUp finds exactly why engines skip you and sells the fix: we repair your site's answer layer, ship the deliverables, and prove the change with weekly receipts. Start with the free 60-second scan to see today's answers. Agencies: white-label it from $29/mo — founding, first 25 seats. We publish our own score weekly, up or down.

  Simple algorithm and color space to generate diverse skin tones▲627

  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 trained a 125M model to autocomplete piano on-device▲598

  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.
