AI is the new front door
More and more users get answers from ChatGPT, Claude and Perplexity instead of Google. Without llms.txt, AI agents crawl your whole site and guess what matters — often missing your best content.
A content map for LLMs
llms.txt gives AI engines a curated, structured summary of your pages so they can understand and cite you accurately. That's the foundation of Generative Engine Optimization (GEO).
Deploys in minutes
Generate → upload to your site root → done. Same effort as robots.txt, with zero dependencies or configuration.
llms.txt vs robots.txt vs sitemap.xml
Three tiny files, three very different jobs. You probably want all three.
| File | Audience | What it does | Format |
|---|---|---|---|
robots.txt | Search engine crawlers | Allows or blocks crawling of specific paths | Plain text rules |
sitemap.xml | Search engine crawlers | Lists every URL for indexing | XML |
| llms.txt | AI engines (ChatGPT, Claude, Perplexity…) | Structured content summary for LLM understanding & citation | Markdown |
