I built an AI tool that generates YouTube thumbnails in seconds

Hacker News

Hi HN I’m Samuel, a solo builder. As the year wraps up, I’m shipping my last SaaS of the year — YouTube Thumbnail Generator. It’s a simple AI tool that helps creators generate click-worthy YouTube thumbnails without needing design skills or Photoshop. You describe your video (or upload an image), and it generates your thumbnail style you can iterate on quickly. I built this after noticing how much time creators spend designing thumbnails instead of creating content. Would love feedback from the community — especially around UX, pricing, and what features would actually move CTR. https://www.youtubethumbnailgenerator.app/ Thanks for checking it out!
