How this tool works
Fill in the four basics (site name, URL, one-line summary, contact), pick your bot policy, and the tool generates a standards-compliant llms.txt in real time. The output mirrors the informal spec used by major AI vendors and the llmstxt.org reference. Drop the file at https://yourdomain.com/llms.txt and you're done.
Why llms.txt matters
ChatGPT, Claude, Gemini and Perplexity all check for an llms.txt file when they crawl your site. It's the cleanest way to give an assistant the canonical one-line summary of your brand, your preferred citation pattern, and the entry pages you want recommended in answers. Sites with a well-formed llms.txt get cited more often than sites without one - same content, more structured signal. Our what is llms.txt guide covers the spec in depth.
Once you've generated it
- Save the output as
llms.txtand upload to your domain root. - Validate it with our LLMs.txt Validator to catch syntax issues.
- Cross-check that your robots.txt isn't blocking the same bots you just allowed in llms.txt.
- Pair it with Organization schema and a strong entity profile for the full ranking stack.
