What is llms.txt?

llms.txt is an emerging open standard for helping LLMs understand your website. It is a single Markdown file at the root of your domain that lists your most important pages in a curated, AI-friendly format.

Think of it as the AI-era equivalent of sitemap.xml, but designed for ChatGPT, Perplexity, and Claude instead of Googlebot. Major companies including Anthropic, Stripe, and Mintlify already publish llms.txt files.

This generator builds a spec-compliant file in 30 seconds by crawling your homepage and sitemap, then organizes the output by content type.

Frequently asked

Everything to know about llms.txt and generation.

What is llms.txt?

+

llms.txt is an emerging open standard (proposed by Jeremy Howard) that helps AI engines like ChatGPT, Perplexity, and Claude understand your website structure. It is a Markdown file at /llms.txt that lists key URLs in a curated format optimized for LLM consumption.

How does this generator work?

+

It fetches your homepage and your sitemap.xml (if available), extracts all internal links, categorizes them by URL pattern (Documentation, Product, Blog, etc.), and outputs spec-compliant Markdown. You can edit the output before downloading.

Where do I put the file?

+

Upload llms.txt to the root of your domain so it is accessible at yoursite.com/llms.txt. The file should not be inside any subfolder. WordPress sites can use FTP or a static-files plugin; Webflow/Framer/Wix have built-in static file or redirect features.

Will the generator pick up every page?

+

Not every page — that would make the file too long for AI engines to ingest efficiently. The tool intelligently selects up to 60 links across categories, prioritizing your most important content (Documentation, Product, Free Tools, Blog). Edit the output to add or remove links.

Should I also create llms-full.txt?

+

For larger sites, yes. llms-full.txt is the verbose companion that lists everything. llms.txt is the curated version. AI engines prefer the curated file but will fall back to the full file if needed.

How often should I update llms.txt?

+

Re-generate every 1-3 months or whenever you publish significant new content sections. AI crawlers re-fetch the file periodically (typically every 1-7 days for major sites).
