Edit Copy
Rewrite any text on the page and read it in place. Better to find out a headline doesn't fit now than after it ships.
Hoverify is a CSS inspector extension that shows the HTML and CSS behind whatever your cursor is on: the rules the page's stylesheets declare, CDN sheets and shadow roots included, as well as the computed values. Edit or copy them without opening DevTools.

Point at an element and the panel fills with its markup and styles. Dock the panel and the page underneath stays clickable while you work.
Source CSS. Switch from the computed values to the rules the page's stylesheets declare, sheets on a CDN included, media queries and keyframes still in place.
Pseudo classes. Rules for :hover, :focus and ::before come through too, so a style can't hide in a state you're not in.
Media queries. Rules from @media, @container and @supports blocks sit with the rest of the element's CSS, and so do its keyframes.
Visual editor. Spacing, typography, borders, background, transforms and position, each with its own control instead of a line of CSS to type.
Syntax highlighting. Highlighted and editable in place, and the editor completes property names and values as you type.
Export. Copy the CSS, send the element and its children to CodePen, or save the HTML and CSS as a file.
HTML attributes. The HTML tab lists the element's attributes as editable fields. Rename one, change a value or add a new pair and the page takes it immediately.
Inner HTML. The markup inside the element opens in an editor of its own. Rewrite it and the page redraws as you type, so you can try a structure before you build it.
Walk the DOM. Arrow keys move the selection to the parent, the first child or either sibling, which beats hunting for a nested element with the cursor.
The panel does more than show styles. You can rewrite copy in place, take elements out of the layout and pull the colors and fonts a page uses.

Hide or erase anything to see the layout without it. Hoverify keeps the list until you reload, so any of it can go back.
The colors the page renders, each with its role and element count, plus tabs for variables, contrast problems and colors that never show. Copy any as Hex, RGB, HSL or OKLCH.
Every font family on the page, where it came from and how many elements use it. Open one for its weights, sizes, file and stack, and see which declared fonts didn't load.
Find elements by tag, id, class or any CSS selector. Hoverify outlines up to 500 matches and scrolls the page to the first one.
Hoverify draws the box model over the element itself, so you see its padding and margin where they actually sit.
Grids. Outline every element on the page at once, so you can see how the layout is actually built.
Guidelines. Horizontal and vertical rules run out from the element you're on, so you can see what lines up with it.
Accessibility. Role, accessible name, contrast ratio and ARIA attributes, with the violations the element trips.
Hover an element or dock its panel, then tell Claude Code or another MCP agent to fix this one. The agent reads its HTML, the CSS rules behind it and the page's fonts and colors. With no agent connected, Copy for AI puts the same HTML and CSS, plus the accessible name, in one block you can paste into any chat.
Hand elements to your agentReviews that call out inspecting by name.
