💡 Use Cases

1. Clean Pasted Content

Users often paste content from Word, Google Docs, or websites that contains messy HTML with inline styles. Use the AI transformation to clean it up automatically.

2. Optimize for Tailwind CSS

When using Tailwind's Typography plugin (@tailwindcss/typography), the AI can remove unnecessary classes and optimize HTML structure.

3. Ensure Accessibility

Transform existing content to meet WCAG guidelines, adding proper semantic HTML, ARIA labels, and improving overall accessibility.

4. Convert Legacy HTML

Modernize old HTML with deprecated tags and attributes into clean, semantic HTML5.

5. Standardize Content

Ensure consistent HTML structure across your application by transforming content to follow your standards.
