What is llms.txt?
llms.txt is a proposed standard file (similar to robots.txt) that lives at the root of your website (/llms.txt). It provides structured information about your site specifically designed for Large Language Models (LLMs) and AI crawlers.
Why You Need It
- AI Discoverability: Helps AI assistants like ChatGPT, Claude, and Perplexity understand and cite your content accurately.
- Control: Tell AI crawlers which pages are most important and how to reference your site.
- SEO for AI: As AI search grows, having an llms.txt file becomes as important as having a sitemap.
- Standard Format: Uses simple Markdown that any LLM can parse.
Basic Structure
A valid llms.txt file should include:
# Site Name— H1 heading with your site name> Short description— Blockquote with a brief overview## Docs— Section listing key pages as Markdown links- [Page](URL)— Individual page links
Frequently Asked Questions
Where should I place the llms.txt file?
Place it at the root of your domain: https://yoursite.com/llms.txt. Just like robots.txt, it must be directly accessible at this URL.
Is llms.txt an official standard?
It's a community-proposed standard (llmstxt.org) gaining rapid adoption. Major AI companies are beginning to respect it, and it's considered a best practice for AI-ready websites.
Does this tool work for any website?
Yes. The AI generator can analyze any publicly accessible website. For the validator, you can paste any llms.txt content regardless of the source.
What if my site is blocked by CORS?
Our generator uses a Cloudflare Worker proxy to fetch your site, so CORS is never an issue. The Worker fetches the HTML server-side and sends only the metadata to the AI.
How do I fix validation errors?
The validator provides specific "Solve Tips" for each issue. Common fixes include adding an H1 heading, adding a blockquote description, and ensuring all links use the - [Name](URL) Markdown format.
