About LLMs.txt

The LLMs.txt Checker is a simple tool that verifies whether your files follow the new LLMs.txt standard. This standard helps Large Language Models (LLMs) access and interpret your website content more effectively. By placing an LLMs.txt file in your website’s root folder, you make it easier for AI systems to understand your site, improving both visibility and compatibility.

Key Validation Rules

The LLMs.txt Checker runs a series of checks to ensure your file is properly structured:

• Markdown Format : Confirms the file is written using valid Markdown.
• Quote Block : Detects a quote block summarizing the project with key details.
• Project Details : Validates optional sections for project information formatted in Markdown.
• File Lists : Ensures H2-level sections contain Markdown lists of files with hyperlinks. Each entry should follow the format: [name](url) with the option to add a colon and comments.
