I kept failing at YouTube thumbnails… so I built a thumbnail generator

I run a small YouTube channel and upload pretty regularly.

The weird part?
Recording and editing videos was never the problem.

Thumbnails were.

I’d spend way too long trying to get them right — testing colors, changing text, moving things around pixel by pixel… and still end up with something that just didn’t perform.

Low CTR, low impressions.
Same story over and over again.

At some point I realized:

This doesn’t scale.

If you’re uploading consistently, you can’t afford to spend 1–2 hours on every single thumbnail.

So I started experimenting.

Not with design… but with automation.


The idea

Instead of manually designing everything, I wanted something simple:

  • describe the thumbnail idea in a sentence
  • get a result instantly
  • iterate fast

Basically treating thumbnails more like prompts instead of projects.

So I built a small tool for myself.

At first it was super rough.
But even the early versions saved me a lot of time.


What changed

The biggest difference wasn’t just speed.

It was iteration.

Before:

  • one thumbnail = a lot of effort
  • testing multiple ideas = annoying

Now:

  • generate multiple concepts in seconds
  • pick what feels right
  • move on

And surprisingly, some of these generated thumbnails performed better than the ones I spent hours on.

Not always, but often enough to notice.


Why I’m sharing this

I originally built this just for myself.

But after using it for a while, I figured other creators might have the same problem.

Especially if you’re:

  • uploading frequently
  • not a professional designer
  • tired of overthinking thumbnails

The tool

I cleaned it up and made it usable online:

It’s still evolving, and I’m actively improving it.

If you try it, I’d genuinely like to hear what works (and what doesn’t).


Curious about your workflow

How are you handling thumbnails right now?

Still fully manual, or already using some kind of tools/automation?
