Build a spec-correct llms.txt, the curated reading list that points AI assistants at your site's key pages, and download it ready for your site root.
Group your key links ("Docs", "Guides", "Pricing"). A section named exactly Optional marks links an AI may skip when short on context.
How it works
Fill in the title, summary, and your curated link sections; the file builds live in the llmstxt.org format: an H1 title, a blockquote summary, and Markdown link lists per section. Copy it or download llms.txt and upload it to your site root.
Honest framing: llms.txt is an emerging proposal and vendor adoption varies; it complements (never replaces) robots.txt and your sitemap. Everything runs in your browser.
Frequently asked questions
What is llms.txt?
A proposed standard (llmstxt.org) for a file at your site root that tells AI assistants what your site is about and which pages matter most, in clean Markdown they can actually use: a title, a one-line summary, and sections of curated links with descriptions.
Do AI systems actually read llms.txt?
Honestly: it is an emerging proposal, not a ratified standard, and adoption among AI vendors is partial and evolving. Publishing one costs you five minutes and gives assistants that DO look for it a curated map of your best content, cheap insurance, not a guarantee.
How is llms.txt different from robots.txt and sitemap.xml?
robots.txt says what crawlers may NOT fetch; sitemap.xml lists every URL for indexing; llms.txt is the opposite of both: a short, human-curated selection of your most useful pages with context, designed for language models with limited context windows.
What should I put in it?
Your product docs, key guides, pricing, API reference, about page, the pages you would show a smart new user first. Group them into sections ("Docs", "Guides", "Policies") and give each link a one-line description. Less is more; this is a reading list, not a sitemap.
What is the special "Optional" section?
The spec reserves a section literally named Optional for links an AI may skip when its context window is tight. Put nice-to-have material there and your must-read content everywhere else.
Where do I upload the file?
At your site root, so it is served at https://yoursite.com/llms.txt, the same placement rule as robots.txt. Download the file here and upload it like any static file.
