What it does

Free social card generator. Design sharp 1200×630 images for link previews, blog hero images, and newsletter covers. No design tools, no signup.

Free social card generator. Design one card, export every platform size: link previews, YouTube thumbnails, squares, stories, and pins. No design tools, no signup.

Design one card, export six platform sizes: the 1200×630 link preview for X (Twitter), LinkedIn, Facebook, and Slack, plus YouTube thumbnails, Instagram squares and portraits, stories, and Pinterest pins. The image you preview is the image you download. No design tools, no signup. Curious how your own post would look? Paste a link and watch it turn into a share-ready card. Title, description, and images fill in automatically. Posts with a custom share image get more clicks, more shares, and look like they were made on purpose. Blank previews and unstyled hero images get scrolled past. If you publish online, you want this done in a minute. Not a Figma file you open once a month. Not a Canva…from betterimage.io

  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'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 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.
