Miniagen - AI thumbnails that boost your YouTube CTR in seconds

Hey Product Hunt! 👋 I built Miniagen because I was tired of watching great videos get buried by weak thumbnails. As a creator, I kept seeing the same pattern: solid content, but a thumbnail that didn't earn the click. Design tools felt slow and clunky when all I wanted was a fast way to test what actually works. So I built Miniagen — an AI thumbnail maker that turns a video link or even just a text idea into multiple high-CTR thumbnail concepts in seconds. No Photoshop, no design background needed. A few things I'm proud of: Paste a YouTube URL or write a prompt — Miniagen generates several styled variations to choose from Create a reusable avatar so your thumbnails stay consistent and on-brand across uploads Edit and refine text, colors, layout, and backgrounds without starting from scratch Export in 4K, ready for YouTube, Shorts, TikTok, and Reels Early users are seeing meaningful CTR gains and cutting their thumbnail production time way down — that was the whole goal: less time designing, more time creating. Would love your feedback, especially on which styles and niches you'd want to see more of. Happy to answer any questions in the comments! 🚀
