ClearRead — Remember what you read
Remember what you read. No AI, no server, no subscription.
What it does
ClearRead transforms any highlighted section in a PDF, EPUB, or Kindle file into an active reading cycle based on the principles of “active recall” and “spaced repetition”—the two most effective techniques supported by evidence in the field of learning science. Each section consists of four steps: predict what’s coming, read, explain in your own words, and then assess your level of recall. The sections reappear on the day you’re about to forget them. A one-time payment of $29. Yours forever.
You finish a book and forget it in two weeks. ClearRead turns your PDFs and ebooks into active reading: predict, read, explain it in your own words, then spaced review locks it in. Works offline. Your data stays yours.
You finish a book, and two weeks later it's gone. That's not your memory failing — that's what passive reading does. ClearRead turns reading into something that stays. The problem isn't you. The problem is that reading only goes one way. Active recall and spaced repetition — the two most evidence-backed techniques in learning science — built into how you read. Guess before you read. Even a wrong guess primes your memory. Say it in your own words. Where you stall is where you didn't understand. Set your exam date. ClearRead works out how much you'll actually remember on that day, splits what's left across the days you have, and hands you one button: start. Exam study is its own space —…from clear-read.com

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.
