Why every AI product looks like an indigo gradient

What it does

Kill AI Slop is a multilingual website that catalogues 33 recurring visual and copy tics—indigo gradients, glowing cards, emoji overload, ALL-CAPS stat cards—common in AI-generated products. Each entry reconstructs the tell in plain HTML with an interactive before-and-after demo showing the clean fix. It also ships as an agent skill that scans web projects for code-level signals of these patterns and proposes (or applies) remediation.

The interesting bit

The site practices what it preaches: it is built as a deliberate rebuttal to the slop it catalogues, using a “paper and ink” design system with a single editorial red, hairline rules, and zero gradients or emoji. The catalogue and the scanner share a single source of truth in catalogue.ts, so the field guide and the fixer never drift apart.

Key highlights

• Catalogues 33 tells observed in real shipped products, not strawmen
• Multilingual field guide (English, Chinese, Japanese, Korean)
• Dependency-free scanner that runs directly against web projects
• Supports custom rules and ignore directives for intentional design choices
• Static Astro site with zero-JS-by-default delivery

Caveats

• The scanner does not edit files when run standalone; automated fixes require an Agent-Skills host such as Claude Code
• Focused on web projects, so its detection patterns are tuned for HTML and web-centric codebases

Verdict

Worth bookmarking if you ship web UI and worry your last coding session left a glowing card or indigo gradient behind. Skip it if your taste is already bulletproof—or if you don’t build for the web.
