llms.txt generator & validator
Create a clean, human-reviewed llms.txt draft from your public homepage metadata. The file acts as a machine-readable discovery index for generative AI engines.
Draft and validation
What belongs in an official llms.txt?
An llms.txt file is designed for automated parsers that need quick, reliable context about your brand without crawling thousands of promotional pages.
Canonical Documentation Links
Links to the home, documentation, pricing, comparison, and technical FAQ pages so language models prioritize canonical URLs.
Limitations & Evidence Grades
Explicit statements of what your product does not do, avoiding AI hallucination and incorrect feature attribution in customer answers.
Context Window Safety
Keep your root file below 5 KB (~1,500 tokens). Massive documentation dumps should go into an optional /llms-full.txt to avoid exceeding agent context limits.

Frequently asked questions
What is an llms.txt file?
An llms.txt file is a markdown-formatted plain text file deployed at your site root or /.well-known/llms.txt that provides AI crawlers with concise entity definitions, key facts, and curated links to essential documentation.
Does publishing an llms.txt guarantee AI recommendations?
No. The file is a discovery aid that reduces extraction ambiguity, not a ranking guarantee. Answer engines evaluate full page content, third-party corroboration, and user context.
Where should the llms.txt file be hosted?
Host it at https://yourdomain.com/llms.txt or https://yourdomain.com/.well-known/llms.txt with content-type text/plain; charset=utf-8, and reference it in your robots.txt or HTML link headers.
What is the recommended size limit for llms.txt vs llms-full.txt?
Keep your root /llms.txt under 5 KB (roughly 1,000–1,500 tokens). Automated retrieval agents use this file as a concise index to discover relevant canonical paths. If you have extensive documentation, publish an optional /llms-full.txt, but ensure individual sections do not overflow the typical retrieval chunk window (typically 2,000–4,000 tokens).
