llms.txt Generator 2026: The AI Site Map That Gets Your Content Cited
llms.txt is a proposed standard (introduced by Jeremy Howard in 2025) - a single markdown file at your site root that tells AI crawlers what your site has and which pages matter. It is the AI-era sibling of robots.txt and sitemap.xml. Perplexity, ChatGPT Search, and other AI tools increasingly consult it.
Why It Matters
- AI crawlers can read it in one request instead of crawling hundreds of pages
- You control which pages are "featured" (the ones you want cited)
- It gives context ("this is a coupon site", "these are our top guides") that raw crawling misses
- Early evidence suggests cited pages correlate with what's listed in llms.txt
The Format
# Example Corp
A short description of the site and what it covers.

How to Generate It
Option 1 - Hand-written (best for small sites). One file, 30 minutes. Just list your best 10-20 pages with one-line descriptions.
Option 2 - llms.txt generator tools. Several open-source generators exist on GitHub (search "llms.txt generator"): they crawl your sitemap.xml and emit the markdown.
Option 3 - Python script. Read sitemap.xml, extract titles/descriptions from pages, write the markdown:
import xml.etree.ElementTree as ET
tree = ET.parse("sitemap.xml")
urls = [u.findtext("{http://www.sitemaps.org/schemas/sitemap/0.9}loc") for u in tree.getroot()]
# write urls into the llms.txt format
Placement Rules
- File must be at https://yoursite.com/llms.txt (root, not /llms.txt.txt)
- Keep it short - 50 entries max, curated
- Update it when you publish important new content
- Link to it from your footer or robots.txt
