Capture the design, tweak manually, export as HTML, send to AI. Protoca Redesigned ✨ AI can generate UI in seconds, but it doesn't know your design system: every LLM prototype starts from generic components that look nothing like your product. Protoca fixes the starting point. It freezes any live page including your production site into a fully self-contained, editable HTML snapshot you can feed straight to an LLM. The AI iterates on your real markup, real styles, real components, so what comes back actually complies with your design. CAPTURE One click (or Alt+Shift+D) freezes the page you're on: assets inline, scripts stripped, layout stays exactly as rendered. The result is a single clean HTML file ideal context for any AI tool. PROTOTYPE WITH AI Export the snapshot, hand it to Claude, ChatGPT, or any LLM, and ask for the change —"add a pricing tier", "redesign the hero", "make this flow mobile-first". Because the AI works from your actual page instead of a text description, the result inherits your typography, colors, and components rather than inventing new ones. Import the result back into Protoca, refine it, and iterate as many rounds as you need. EDIT Click anything to select it. Drag to move, pull the handles to resize, double-click text to rewrite it. Floating Properties and Layers panels appear next to your selection — position, type, color, effects, visibility, lock. Smart guides snap elements into alignment. Full undo/redo through every change. Press ? for the complete keymap. EXPORT Download your redesign as a standalone HTML file (LLM-ready), a PNG, or a ZIP. What you export is the page itself, edited — not a mockup of it. BUILT FOR DESIGNERS Prototype directly on your production site with AI, without touching the codebase. Iterate on copy, layout, and new features while staying design-compliant. Redesign a competitor's landing page in front of a client. Turn any page on the web into a starting point instead of a reference tab. PRIVATE BY DESIGN Everything lives in your browser's local storage. Nothing is uploaded, nothing is tracked, no account needed. Protoca only touches a page when you explicitly capture it, and nothing reaches an AI unless you choose to share the export.
