Show HN: I built an AI tool that generates YouTube thumbnails in seconds

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.

Thanks for checking it out!

Does it use the video to extract the face of the person or the background?
