The Chrome Web Store rounds user counts down to the leading digit, so the user line moves in steps. The ratings count is exact and is the better signal of real adoption.

About Design Prompt Builder

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.
