About
Instead of writing "the blue button in the top-right of the dashboard card," you click it — and get structured context with HTML, selectors,
computed styles, and page context, ready to paste.
── ELEMENT PICKER (Alt+Shift+P) ──
Click any element on any webpage to capture it. Gets serialized with ARIA role, label, semantic HTML snippet (CSS-in-JS hashes stripped),
unique selector, and computed styles. Works inside Storybook iframes.
── FREE-FORM PROMPT EDITOR ──
Write natural language with inline element references:
"Move [el-1] closer to [el-2] and make [el-3] red"
Picking an element inserts a token at your cursor position. Each reference expands to full HTML + style context when copied.
── DOM EDITOR (Alt+Shift+E) ──
Live-edit the page to show AI exactly what you mean:
• Text edit — click to edit text content inline
• Resize — drag corner handle to change dimensions
• Move — pick up any element and place it anywhere in the DOM, even in a different container
• Style controls — visual panel for flex-direction, justify-content, align-items, gap, margin, and padding with live preview
── ONE-CLICK COPY ──
All captured elements and DOM edits assemble into a structured prompt with full HTML context, styles, and a clear implementation instruction.
Built for frontend developers and designers who use AI coding assistants and need to communicate visual changes precisely — without writing
long manual descriptions.Technical
