Website Cloner
View DemoBuilt an end-to-end AI pipeline that automatically converts real websites into fully functional React + Tailwind applications. The system captures full-page screenshots and DOM using Puppeteer, intelligently splits large pages into semantic visual sections, and uses a multi-model vision-LLM cascade to reconstruct pixel-accurate UI components. It integrates HTML and CSS semantic analysis to preserve layout, content, and design while eliminating noise from hydration scripts and trackers. The pipeline outputs a complete, ready-to-run React project with merged components, layout fidelity, and minimal hallucination.
