Step 1
Source.
Paste a URL or drop a ZIP. That is the only input. No plugin, no Figma file, no redesign pass.

Design QA, not a redesign
Paste a URL. Get numbered marks and one prompt for the issues you keep.

Step 1
Paste a URL or drop a ZIP. That is the only input. No plugin, no Figma file, no redesign pass.
Step 2
Versioned design skills read the page the way a designer would: layout, type, hierarchy, and the patterns that keep showing up.
Step 3
What you keep becomes one implementation prompt. Copy it or download it. You decide what runs.

Typography
Sans-serif heading surrounded by serif typography creates inconsistent hierarchy and makes the design feel less intentional.
Alignment
Misaligned content creates visual friction and makes the page feel unstructured.
Spacing & Radius
Uneven spacing and corner radii make the interface feel disconnected.
Color
Overused yellow and cream tones can make a landing page feel generic, especially when they aren't tied to a distinct brand identity.
Gradients
Gradient buttons add visual noise and weaken action hierarchy.
Background
Blurred shapes add visual noise without adding meaning.
FAQ
Short answers on what it marks, what you submit, and what you decide to keep.
Start an auditNo. It marks problems and writes one implementation prompt from the issues you keep. You decide what runs.
A public URL or a ZIP of the project. No plugin and no Figma file. GitHub and pages behind a login come later.
No. Review the numbered marks, drop the ones that are taste or on-brief, and keep the rest. Only what you keep goes into the prompt.
The patterns that make a page feel templated: layout, type, spacing, hierarchy, components, and generic AI defaults. Same tells as the use-cases section — mixed typefaces, inconsistent alignment, spacing and radius, generic palettes, gradient buttons, and blurred backgrounds.
It judges by context. A marketing page is allowed to be bold; an app should stay consistent. Unusual layout on a portfolio is not automatically a bug. It flags defaults, not taste.
Versioned design skills, not hardcoded product logic. Change a skill, and the next audit uses the new bar, without shipping a new app.
Lighthouse scores speed and runs generic checklists. Slopscan judges the design against its context, marks the slop, checks whether Google and AI assistants can actually read the page, then gives you one prompt for the issues you keep.
Get Started
Start with a live URL. Review the marks. Keep the ones that matter.
