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, so nothing you type is transmitted, logged, or stored anywhere. You can even use it offline once the page has loaded.
