About this tool

Create a reviewable llms.txt draft using the ordered Markdown structure proposed by llmstxt.org, with explicit resource titles, URLs, descriptions, and optional context.

LLMs.txt Generator creates the ordered Markdown profile described by the llmstxt.org community proposal: an H1 title, blockquote summary, optional non-heading context, and H2 sections containing titled resource links with optional descriptions. A generated Optional section retains the proposal's special shorter-context meaning.

  • Generates an H1 title, blockquote summary, optional pre-section context, primary H2 link list, and special Optional section in proposal order.
  • Parses Title | URL | Description rows and validates bounded text, headings, HTTP(S) URLs, credentials, duplicates, and reserved section semantics.
  • Escapes Markdown link titles and destinations, then exports exact TXT and versioned JSON evidence only when input is valid.
  • States that llms.txt is a community proposal and does not guarantee discovery, retrieval, indexing, ranking, citation, licensing, or crawler behavior.

How to use LLMs.txt Generator

Enter the project title, concise summary, optional context, and primary section heading. Add one resource per line as Title | HTTP(S) URL | Optional description, place secondary resources in the Optional list, resolve field errors, review warnings, and download the exact TXT or JSON evidence only after checking every link.

When this tool is useful

  • After pruning low-value pages from a tool directory or content hub.
  • When publishing a curated context entry point for documentation or product resources.
  • When reviewing an existing llms.txt file against the proposal's link-list structure.

Practical tips

  • List representative high-value pages, not every URL on the site.
  • Give each resource a distinct title and a brief factual description instead of listing bare URLs.
  • Use the Optional section only for resources that can be skipped when a shorter context is needed.
  • Do not describe publication as guaranteed AI search discovery, ranking, or crawler control.

Build an llms.txt file for a tool site

Example input

Title: Utiloom
Summary: Focused browser-based workbenches...
Primary resources: Tool directory | https://www.utiloom.com/tools | Browse the public catalog.

Expected output

# Utiloom

> Focused browser-based workbenches...

## Primary resources

- [Tool directory](https://www.utiloom.com/tools): Browse the public catalog.

The generated file follows the proposal's H1, blockquote, H2, and described Markdown link structure.

Catch weak discovery files

Example input

Primary resource: Unsafe | javascript:alert(1)
Optional resource repeats the same normalized URL

Expected output

Field errors suppress the generated output, copy action, and TXT or JSON downloads.

The validator rejects malformed rows, non-HTTP(S) URLs, credentials, duplicate URLs, and reserved heading conflicts.

Validation checklist

  • Confirm every linked URL is accurate, accessible to its intended audience, and useful as context.
  • Confirm the file contains one H1 followed by its blockquote before any H2 resource sections.
  • Review whether Optional resources can genuinely be skipped for a shorter context.
  • Test the deployed response path and media type separately because this generator does not fetch or publish files.

Frequently asked questions

What is an llms.txt file?

llms.txt is a community proposal for a Markdown file that gives language models concise site or project context and links to detailed resources. It is not a robots.txt directive or an established web standard.

Does llms.txt directly improve Google rankings?

No direct ranking boost is guaranteed. The value is clearer machine-readable context for AI search and assistant systems, while traditional SEO still depends on crawlability, helpful content, links, and trust.

What should I include in llms.txt?

The proposal defines an H1 title, a blockquote summary, optional non-heading context, and zero or more H2 sections whose list items contain titled links and optional descriptions. A section named Optional has special context-size meaning.

Do AI crawlers automatically discover or obey llms.txt?

No. Provider adoption and processing behavior vary, and publishing the file does not guarantee discovery, retrieval, indexing, ranking, citations, or content-use outcomes.

Is this generated file uploaded anywhere?

No. The generator runs in your browser and produces text you can review before publishing at /llms.txt on your own site.
