llms.txt Generator
Generate a spec-compliant llms.txt file — the file AI models like Claude, ChatGPT, and Perplexity read to understand your site — from your site name, summary, and doc links.
About this tool
llms.txt is a plain-Markdown file — think of it as a robots.txt for AI — that tells large language models what your site is about and which pages matter most, in a format they can parse far more reliably than crawling your full HTML. This generator builds one from your project name, a one-line summary, an optional longer description, and lists of documentation and optional links, following the llmstxt.org specification.
Fill in the fields and the output updates live in the box below: a Markdown H1 with your project name, an optional blockquote summary, any context paragraphs, then an H2-sectioned list of links in the exact "[Title](URL): description" format the spec expects. Copy the result or download it as llms.txt and drop it in your site's root directory.
Common uses
- Give AI assistants and answer engines a reliable, structured summary of your product or documentation site
- List your most important docs pages so an LLM cites the right URL instead of guessing
- Add a short licensing or usage note for AI crawlers, in the same file they already check
Frequently asked questions
Do search engines like Google use llms.txt?
No — llms.txt is read by AI language models and answer engines (Claude, ChatGPT, Perplexity, and similar), not by traditional search-engine crawlers like Googlebot, which still rely on robots.txt and your sitemap. The two files serve different audiences and are meant to coexist.
Where do I put the generated file?
Save it as llms.txt in your site's root directory, the same level as robots.txt, so it's reachable at https://yoursite.com/llms.txt.
Is llms.txt an official web standard?
It's a community-driven, widely-adopted convention (from llmstxt.org) rather than a W3C or IETF standard, but major AI tools including Anthropic's Claude already fetch and read it, and it's gained enough traction that Google added llms.txt checks to Lighthouse's agentic-browsing audits in 2026.
Is my data uploaded to a server?
No. This tool runs entirely in your browser using JavaScript — nothing you type is transmitted, logged, or stored anywhere. You can even use it offline once the page has loaded.
