Just launched Miniagen — an AI tool to generate YouTube thumbnails that actually get clicks.
Why I built this:
I noticed most creators either:
Waste hours on design
Or ignore thumbnails and lose views
Thumbnails = CTR = growth.
What MiniAgen does:
• Generates thumbnails based on viral patterns
• Optimized for engagement (not just aesthetics)
• Takes seconds instead of hours
Current stage:
👉 Early users testing
👉 Iterating based on feedback
👉 Focusing on CTR improvements
Next steps:
• A/B testing features
• Style personalization
• Data-driven optimization
Would love honest feedback from the community 🙏
Roast it, break it, or tell me what you'd build next.

The interesting part isn’t generating thumbnails faster.
It’s whether you’re helping creators generate better click decisions.
Most thumbnail tools stop at design speed.
The real value is reducing guesswork on what actually earns the click.
If Miniagen becomes “make me 5 variations ranked by expected CTR” instead of just “here’s a thumbnail,” that gets much more valuable much faster.
Speed gets attention.
Prediction gets retention.
That’s exactly how we think about it.
MiniAgen isn’t about speed that’s just a bonus.
It’s built to maximize CTR first.
The goal is simple: help creators get more clicks, not just nicer thumbnails.
It’s free you should give it a try 👉 https://miniagen.co
MiniAgen is clean, but “AI thumbnail generator” undersells it.
That gets read like another design tool.
If the real value is CTR, the stronger frame is:
not “make thumbnails faster”
but “pick the thumbnail most likely to win.”
That’s the part I’d pressure-test hardest.
ok thanks you
