No account needed. We don't store what you enter or the result.
What this tool checks
- We fetch /llms.txt and check that it is a text file and not an HTML page (a common mistake when a 404 is served as a page).
- We look at the llmstxt.org structure: one H1 with the name, a summary as a blockquote (>), H2 sections and Markdown links.
- We check the content type: text/plain or text/markdown.
- We check whether there is also an llms-full.txt with the full text of your most important pages.
