Show HN: I built an AI thumbnail generator for YouTubers who can't design

1 isacbuilds 0 6/24/2025, 8:18:57 PM thumbo.io ↗

I've been wanting to start a YouTube channel for years but kept putting it off because I can't make decent thumbnails and hiring designers is too expensive for me.

So I built thumbo.io - upload a photo + text prompt and get studio-quality YouTube thumbnails in ~60 seconds. No design skills needed.

If you're able to try it, I have a coupon code "HN100" for the first 5 people who want to try it free (I wish I could give more, budget is tight).

I'd really appreciate any feedback on the product, UX, pricing, or anything else. Thanks!
