Make the web yours.

Aevilo lets you inspect, redesign and animate websites in Chrome. Start with the visual tools, explore what a page is made of, and save the changes you want to keep.

Architectural construction

Pages assemble like architecture.

As a page opens, Aevilo draws its structure, measures its geometry, then lays every surface into place. Nine styles, from Architectural to Silk and Depth, at the speed you choose.

Aevilo Inspector

Read any page like its designer.

Hover to outline, click to inspect. Size, spacing, type and colour are measured from the page itself, next to CSS you can copy. Try it on this fictional page.

Motion Studio

Original motion, no code.

Select an element on the stage, start from a preset or shape its start state, then arrange the sequence on the timeline. Saved presets play whenever you return to the site.

Aevilo AI

Say it. See it. Apply it.

Describe a change. Aevilo proposes the CSS, previews it on the page, and applies it only when you say so. In the extension, on-device AI depends on Chrome model availability; a clearly labeled reference mode is available without it.

Paid workspace · Pro Studio

More room for bigger ideas.

When you want a full canvas, layers, design controls and a motion timeline together, Pro Studio brings them into one workspace. It is part of the paid experience; the everyday Aevilo tools remain the place to start.

A studio that remembers.

Persistent website themes

One theme per site, turned on or off in a click, with up to 15 earlier versions to restore. Restore original puts the real site back instantly.

Design-system discovery

Measure a page’s palette, type scale, spacing, radii and shadows. Compare two sites, or turn the measurements into a light and a dark theme.

Asset exploration

Every image, background, inline SVG and icon on the page, with size, format and alt-text status. Locate any of them on the page.

Presets and exports

Save animations as presets per website or page. Export them as readable CSS, CSS with a small script, or a recipe others can import.
