ThumbRank

Preview your YouTube thumbnail before publishing

What it does

See how your thumbnail looks in real YouTube search results before you hit publish. Get an AI CTR score, compare with competitors, and fix weak spots while you still can. Freemium: 3 free previews/day.

ThumbRank lets creators preview how their YouTube thumbnail looks in a real search results mockup. Test against competitors, run A/B tests, and get a CTR score — all in your browser.

ThumbRank helps YouTube creators see how their thumbnails look against real competitor search results without burning early views on guesswork. No more guessing. Preview, score, and compare before you publish. See exactly how your thumbnail looks on a phone screen surrounded by real competitors. Get an instant quality score based on contrast, composition, and clutter analysis. Upload up to 2 competitor thumbnails and see which one wins the scroll. All processing happens in your browser. Zero server uploads. Your thumbnails never leave your device. I spent 3 years growing a YouTube channel from 0 to 50K subscribers. The one thing that moved the needle every single time? The thumbnail. Not…from thumbrank-youtube-th-n5m8.bolt.host

    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.
