The llms.txt proposal
llms.txt: a plain-text reference for AI engines
Publish a concise reference to your most useful public information. Support for the emerging llms.txt proposal varies by AI product, so treat it as one clear signal alongside the rest of your public presence.
What is llms.txt?
llms.txt is a plain-text file placed at the root of your website, similar to robots.txt, that gives AI language models structured, accurate information about your business: what you do, what you offer, how you are priced, and what makes you different.
AI assistants like ChatGPT, Claude and Gemini are becoming another place where buyers research businesses. A well-written llms.txt gives compatible tools a concise map of factual, public pages. It complements, rather than replaces, clear website copy, structured data and authoritative third-party sources.
Like robots.txt
Placed at your root URL. Simple plain text. No coding required.
Written for AI engines
Natural language plus light structure, instead of markup for search crawlers.
Easy to update
Revise it as your public information changes; how soon AI products pick up changes varies.
The specification
Everything you need to create a valid llms.txt file.
File Location
Place your llms.txt file at the root of your website, accessible at:
https://yoursite.com/llms.txt https://yoursite.com/llms-full.txt (extended version)
Required Structure
Every llms.txt file must start with a heading and description block:
# Your Company Name > Your one-line description. What you do, who you serve, what makes you different.
Recommended Sections
Add these markdown sections to give AI engines structured information about your business:
## About [Full description of your company, mission, and background] ## Products - **Product Name**: Brief description - **Another Product**: Brief description ## Pricing - Free tier: what's included - Paid plans: price and features ## FAQ Q: Common question AI engines ask? A: Your direct answer. ## Links - Homepage: https://yoursite.com - Documentation: https://docs.yoursite.com - Support: support@yoursite.com
llms-full.txt (Extended Version)
For comprehensive coverage, also create an llms-full.txt with detailed information:
# [Company] — Extended AI Reference File > [Detailed description] ## Detailed Product Descriptions [Full product documentation AI can cite] ## Case Studies [Success stories with specific metrics] ## Competitor Comparison [How you compare to alternatives — be factual, not promotional] ## Technical Specifications [For technical products: API docs, integrations, requirements]

Questions
Is llms.txt an official standard?
No. llms.txt is an emerging proposal from the community, not an official or universal standard. Adoption and support vary by AI product.
Do AI engines actually read llms.txt?
llms.txt is an emerging proposal, not a universal standard. Some tools may use it as a concise reference, but support varies and publishing one does not guarantee ingestion, training, or citations.
How is llms.txt different from robots.txt?
robots.txt is a widely supported crawler-control standard. llms.txt is a voluntary content reference intended to summarize useful pages; it does not control crawling or model behavior.
How is it different from schema markup?
Schema markup is structured JSON-LD embedded in your HTML for search engines. llms.txt is a plain-text file optimized for AI language models — it is easy to read and to publish: you upload a single text file.
How often should I update my llms.txt?
Update it whenever your products, pricing, or business description changes. At minimum, review it quarterly to ensure accuracy.
Can I have multiple llms.txt files?
Yes. Use llms.txt for the summary version and llms-full.txt for comprehensive information. Some businesses also create topic-specific files like /products/llms.txt.
Will this immediately improve my AI visibility?
No outcome is guaranteed. Treat llms.txt as one clear, machine-readable reference alongside strong public pages, structured data, and independent citations, then measure changes over time.
