Metadata Reactor - Upload any image → instant AI metadata for 11 platforms

Hey Product Hunt! 👋 I built Metadata Reactor because I was tired of watching creators spend more time writing about their content than actually creating it. A YouTube creator uploads a thumbnail and then manually writes titles, descriptions, and tags. An Etsy seller photographs a product and then manually writes a 140-char SEO title, 13 tags, and a full listing. A stock photographer uploads 50 images and manually keywords every single one. That's backwards. The image already tells the story — the AI should read it. So I built a tool that does exactly that. Upload any image → Gemini Vision AI analyzes it → you get complete, platform-native metadata in seconds. Not generic output — actual YouTube-optimized titles, actual Etsy 13-tag sets, actual Adobe Stock keyword packs up to 50 keywords. 11 platforms live today: YouTube, Etsy, Adobe Stock, Redbubble, Pinterest, Instagram, TikTok, Facebook, X, Amazon, and Shopify. Free to try — no card needed. I'd love to know: which platform's metadata do you find most painful to write manually? 👇
