Hey Product Hunt! 👋 I'm Alex, and I built Thumblr because small YouTubers aren't necessarily graphic designers and don't necessarily have the means to hire a professional. The problem? Great thumbnails take forever to design, and most creators aren't designers. The solution? Describe your idea in plain English, and AI generates scroll-stopping thumbnails in seconds. But here's what makes Thumblr different: 🎨 Sketch Mode — Can't describe what you want? Just draw it! Sketch your rough idea directly in the canvas, and AI transforms your doodle into a professional thumbnail. It's like having a designer who reads your mind. 🧩 Chrome Extension — Preview your thumbnails directly on YouTube before uploading. See how they look in search results, on the homepage, or next to competitors. Test, compare, then publish with confidence. 🔍 Explore & Get Inspired — Stuck on ideas? Browse our public gallery to see what other creators are generating. Find a prompt you love? Use it as a starting point for your own thumbnail. No more staring at a blank canvas. 🚀 Built for iteration — Each generation is a conversation. Refine your prompt, add reference images, tweak the style until it's perfect. And more to come ! We're offering 5 free credits to try it out — no credit card required. I'd love to hear your feedback! What features would make this more useful for your workflow?
