AI Site Guide Maker (llms.txt) & Size Checker
Help ChatGPT, Claude, and Perplexity understand what your website offers. Fill in your top pages below and download a clean llms.txt file in under two minutes.
llms.txt file sits at the root of your website and gives AI assistants a compact, clutter-free menu of your top links under 3,000 reading units so tools like ChatGPT and Perplexity summarize your pages accurately.Why AI Assistants Love a Simple Site Guide
When someone asks ChatGPT, Claude, or Perplexity a question about your niche or business, the AI tool only has a few seconds and limited reading space to skim your website. Regular web pages are packed with navigation bars, sidebars, and styling code that make it harder for AI to spot your core facts.
An llms.txt file strips away all that visual clutter. It gives AI tools your business name, a clear one-sentence description of what you do, and direct links to your most helpful pages — like your pricing, menu, shipping policy, or top tutorials.
