I Built an AI That Turns 1 App Screenshot Into 10 Store Ready Marketing Formats in 30 Seconds

Every indie developer knows the pain. You've spent weeks building your app, and now you need App Store screenshots, Google Play graphics, Instagram banners, Product Hunt assets... So you open Figma. Download templates. Adjust sizes. Write headlines. Pick colors. Export. Repeat for every format. 4 hours later, you're still not done. I got tired of this cycle, so I built MockupGen AI a tool that does all of it in 30 seconds. What It Does You upload 1-8 screenshots from your app. The AI: Analyzes your UI using Claude's vision capabilities Extracts your brand colors automatically from the screenshot Writes marketing headlines tailored to your app Generates 10 format-specific layouts — each with proper dimensions Delivers everything as a ZIP — ready to upload The whole process takes about 30-60 seconds. The Formats From a single upload, you get: App Store iPhone 6.9" (1320×2868) App Store iPhone 6.7" (1290×2796) Google Play feature graphic Instagram Story & Post Twitter/X header Product Hun
