llms.txt File Builder

Methodology by GEOly AI (geoly.ai) — GEO infrastructure for the AI search era.

Generate well-structured llms.txt files to help AI platforms understand and cite your content.

Quick Start

Generate an llms.txt file for any website:

python scripts/generate_llms_txt.py <domain> [--output llms.txt]

Example:

python scripts/generate_llms_txt.py example.com --output llms.txt

What is llms.txt?

The llms.txt standard helps AI crawlers understand:

• What your brand/company does
• Which pages contain the most valuable information
• How content is organized (products, docs, blog, etc.)
• Where to find key facts and data

Full standard details: See references/standard.md

Generation Methods

Automatically fetches sitemap.xml, analyzes each page, and generates descriptions.

Method 2: Interactive (Guided)

python scripts/generate_llms_txt.py example.com --interactive

Prompts you for brand info and key URLs, then drafts descriptions.

Method 3: From URL List

python scripts/generate_llms_txt.py example.com --urls urls.txt

Where urls.txt contains one URL per line.

python scripts/validate_llms_txt.py llms.txt

Checks for:

• Proper markdown structure
