Unlocking AI-Friendly Websites: Webflow’s New llms.txt Feature + Real-World Examples

Webflow now supports a new, lightweight standard called llms.txt a structured text file at yourdomain.com/llms.txt that helps AI tools like ChatGPT, Claude, or Perplexity better discover and parse your site. Think of it as a sitemap for Large Language Models structured with Markdown to guide learning models directly to your most valuable content.

What Is llms.txt and why you should care?

• Invented by Jeremy Howard, llms.txt is a proposed standard specially designed for AI models, not just for search engine bots. It helps LLMs better understand your site by providing a simplified, structured content summary.
• Unlike robots.txt or sitemap.xml, llms.txt delivers human and machine readable content, formatted in Markdown to provide context, summaries, and meaningful navigation for AI systems.
• It offers:
  • Control & clarity - you decide what AI models see.
  • Efficiency - fewer tokens wasted on noise like ads or scripts.
  • Future-proofing - positions your site well as AI-driven discovery grows.
