What is an llms.txt file?

llms.txt is a plain-text manifest at the root of your website (yourdomain.com/llms.txt) that tells AI systems like Claude, Perplexity, ChatGPT browse, and Bing Copilot what your site is about and which pages they should prefer when answering user questions. It follows the open llmstxt.org specification.

Yes. The tool is 100% free, requires no signup or credit card, and returns a properly formatted llms.txt file in about 30 seconds.

Where do I upload the llms.txt file?

Upload llms.txt to the root of your website at the same level as robots.txt. Verify it loads at yourdomain.com/llms.txt with a plain-text content type.

How is llms.txt different from robots.txt?

robots.txt controls which crawlers may fetch which URLs. llms.txt is the opposite: it actively recommends the pages AI systems should cite and summarize, with a brand description and prioritized link list.
