I built Miniagen to help creators make better thumbnails in seconds
I launched Miniagen, an AI tool that turns video ideas into scroll-stopping thumbnails for YouTube, Shorts and Reels.
Why I built it:
Most creators either:
spend way too much time designing thumbnails, or
publish weak thumbnails and lose potential views.
But thumbnails are one of the biggest levers for CTR.
So I wanted to make something dead simple:
Type an idea → get multiple thumbnail options → pick one → publish faster.
Current stage:
Free to use
Early users testing it
Improving based on feedback
Exploring whether creators would pay for advanced features
I’d love your honest thoughts:
Would you use this for your own content?
What feature would make it 10x more useful?
Would you pay for thumbnail generation if it improved CTR?

Solving the "weak thumbnail" problem is a high-leverage entry point for new creators. Most tools focus on the generation part, but the real value is in the CTR prediction/logic.
One thought on Miniagen: since you're exploring whether creators would pay, I'd suggest a "CTR Audit" mode where a user uploads their current thumbnail and the AI compares it against your "scroll-stopping" baseline. That contrast is usually what triggers the "I need this" purchase decision.
If you'd like a substantive conversion teardown of the Miniagen landing page or the generation flow, I do them for $1 here: https://roastmysite.io/go.php?src=external_manual_ih_kokau_miniagen_may19_usd_presell_hv
