Free llms.txt generator
Chrome Lighthouse now includes an agentic browsing audit for llms.txt. Generate a clean draft that tells AI agents what your site does and which pages matter.
Paste your website URL. The tool reads the homepage, extracts the title, description, canonical URL, and key internal links, then turns them into a concise Markdown file.
Lighthouse treats llms.txt as optional today. The opportunity is speed: give AI agents a cleaner starting point instead of making them infer your site structure from scratch.
Output: save this as llms.txt at the root of your site.
Made for agents
Markdown format, short summaries, and key URLs make the file easy for AI systems to parse.
Useful for GEO
Use llms.txt alongside schema, sitemap hygiene, answer-first pages, and external entity signals.
Root-file ready
Copy the output and publish it at /llms.txt so agents can find it without guessing.
