llms.txt Checker & Generator

Check if your website is discoverable by AI assistants. Analyze your llms.txt and generate one instantly.

What is llms.txt?

llms.txt is a Markdown file at /llms.txt on your domain, inspired by robots.txt. It gives AI assistants (ChatGPT, Claude, Perplexity, Gemini) a clear, structured map of your site's most important content, improving how AI systems understand, cite, and recommend your website. A companion /llms-full.txt can include the full text of key pages.

Google Now Recognizes llms.txt

Google's AI systems are trained on web content. Here's why your site needs to be ready.

Google AI Overviews

Google's AI Overviews (formerly SGE) now appear at the top of search results for hundreds of millions of queries. Sites with structured, AI-readable content are cited more often than those without.

Gemini Web Grounding

Google Gemini uses web grounding to pull live information from indexed websites. A clear llms.txt helps Gemini identify your most important pages when answering questions about your domain.

AI Crawlers Are Here

Google's AI training crawlers (GPTBot, Claude, Google-Extended) already respect well-structured content signals. llms.txt acts as a priority map for these crawlers, guiding them to your best content first.

Early Mover Advantage

Adoption of llms.txt is still low. Websites that add it now gain a significant edge as AI search becomes the dominant discovery channel. Google rewards sites that invest early in AI readiness.

Why llms.txt Matters for AI Discoverability

AI Citation Readiness

ChatGPT, Perplexity, and Claude browse the web. A structured llms.txt helps them surface your most important pages when answering questions about your domain.

Content Hierarchy Signal

llms.txt tells AI systems which pages matter most: your docs, product pages, and core content, instead of letting them guess from crawl order.

5-Minute Setup

Unlike schema markup, llms.txt is just a plain text file. Generate it here, upload it to your server root, and you are done.

Complements robots.txt

robots.txt tells crawlers what not to index. llms.txt tells AI assistants what to prioritize. They serve different purposes and work together.

Also Fix Your Schema Markup

llms.txt improves AI discoverability. JSON-LD schema markup improves Google Rich Results. Use both for maximum visibility.
