llms.txt is a Markdown file proposed in September 2024 that describes a website to AI assistants. It uses headings and lists to give a clean overview of the site's structure and most important pages, in a format easier for language models to read than full HTML. Read the spec at llmstxt.org.
The name of your website or product. Appears as the top-level # heading in the generated file. Example: "Acme Coffee Roasters", "IndexWolf".
The full homepage URL of your site (with https://). Used as the canonical link for the site in the generated file. Optional but recommended.
A short single-sentence description of what your site does. Appears as a Markdown blockquote in the generated file and is the line AI assistants are most likely to quote. Example: "Specialty coffee roasted in small batches in Brooklyn."
Multi-sentence context about your site: history, what you sell, who you serve. Appears as plain prose paragraphs after the summary blockquote. Useful for AI assistants answering "Tell me about X" questions.
Grouped lists of links to important pages on your site (e.g., "Products", "Documentation", "Blog"). Each section has a title and one or more link rows. Each link row has a page name (required), URL, and optional short description. Sections become ## headings in the generated file; links become bulleted Markdown links.
"+ Add section" creates a new empty section. "Load example" fills the entire form with a realistic example (useful to see the format). "Reset" clears all input fields. None of these touch your site; they only modify the form.
No. An llms.txt file does not grant or change access. Site access is controlled by your hosting setup and by robots.txt. llms.txt is purely a description. If AI does read your site, this file gives it a clean summary. If AI is blocked from your site, llms.txt is never read.
Only if you want AI assistants to have a clean, accurate summary of your site when they read it. It is optional. Many sites work fine without one.
No. Everything runs in your browser. The form input never leaves your device.
