What this is

You read the jvns.ca post and decided today is the day. This tool takes a Tailwind-soup component and gives you back the same markup with semantic class names plus a real stylesheet — BEM, CSS Modules, or vanilla scoped.

• HTML is parsed with parse5; JSX with @babel/parser. Repeated full class-strings (≥2 elements) become clusters.
• Each Tailwind utility is resolved to its real CSS declarations using a SQLite mirror of tailwindlabs/tailwindcss theme.css — synced weekly.
• Claude names the clusters semantically (e.g. card-hero, not cluster-0). Values are never LLM-guessed.
• Five free conversions per IP per UTC day. No accounts, no signup. The permalink is the share unit.
