llms.txt Generator

llms.txt is a proposed standard file (similar to robots.txt) that provides a plain-text, Markdown-formatted summary of your website specifically designed for large language models (LLMs) and AI agents. It helps AI systems like ChatGPT, Claude, and Perplexity quickly understand what your site offers, its key pages, and how to navigate your content — without needing to crawl every page.

Place your llms.txt file at the root of your website, accessible at https://yourdomain.com/llms.txt. Some implementations also support /.well-known/llms.txt. Make sure the file is served as plain text (text/plain or text/markdown) and is not blocked by your robots.txt file.

robots.txt tells crawlers which pages they can or cannot access — it controls permissions. llms.txt is different: it provides a structured summary of your site's content, purpose, and key pages specifically for AI consumption. Think of robots.txt as the bouncer (who gets in) and llms.txt as the tour guide (here's what's important). You need both for optimal AI agent readiness.

While llms.txt is not yet a universal standard, adding one is a strong signal of AI-readiness. AI agents are increasingly looking for llms.txt to quickly understand websites. Early adopters get better AI visibility — when an agent can read your llms.txt, it understands your site faster and recommends it more accurately. It takes 30 seconds to generate one, so the cost is minimal.

Absolutely. The generator creates a starting template based on your site's metadata, but you should customize it. Add details about your products, services, API documentation, and any other information that would help an AI agent understand and recommend your business. The more context you provide, the better AI agents can represent your site.
