llms.txt is a simple text format (see llmstxt.org) that helps AI systems and crawlers understand what your site offers. It often lists important URLs with short descriptions so models can prefer the right pages.

Where do I get the URL list?

Use our Sitemap URL Extractor to pull URLs from sitemap.xml or robots.txt, then copy the list and paste it here. You can also paste any plain list of https URLs, one per line.

Do I need to edit the generated file?

Yes. The builder creates a draft. You should review sections, fill in the optional LLM notes, and adjust wording to match your site’s policies before publishing at /llms.txt.

Is anything sent to your servers?

No. The preview and download are generated entirely in your browser.

Publish an llms.txt that helps AI crawlers find the right pages

llms.txt is a simple convention — like robots.txt for AI crawlers — that tells models which pages are most useful and how to summarize your site. Building one manually is tedious; generating one from a URL list takes seconds and gives you a clean draft to refine before publishing at /llms.txt.

Use the builder when you need to

Adopt llms.txt on your site

Generate a starter file from your existing URL list instead of writing the structure by hand.

Help models cite the right pages

List your canonical guides, docs, and reference pages so AI tools surface the strongest content.

Document an API or product surface

Pair llms.txt with sitemap.xml so crawlers and models both pick up the canonical URL inventory.

How to build an llms.txt file

1
Paste your URL list (one URL per line, or output from the sitemap extractor).
2
Add a title, description, and optional notes for LLM consumers.
3
Preview the generated llms.txt and download or copy the result for upload to /llms.txt.

Keep going

Get the URL list

Pull URLs from sitemap.xml or robots.txt to feed straight into the builder.

Encode URL components

Verify URL responses

Send a quick request to each URL to confirm it returns the expected content.
