How it works

This utility runs entirely in your browser using secure client-side code. Your inputs and configuration parameters are never sent to a backend server, guaranteeing absolute privacy.

How to Validate and Lint Your LLMs.txt Document

AI search crawlers rely on clean markdown configurations. The LLMs.txt Validator audits syntax, H1 headers, blockquote summaries, and link formats to guarantee complete readability.

The Impact of Broken Formats

Invalid brackets, missing description colons, or unescaped URLs can break bot parsing engines, causing crawlers to skip important sections. Always validate your syntax before deployment.

Tool FAQ

Why are relative links warned?

AI bots index pages globally and relative links (e.g., /docs) can break. Always use absolute URLs beginning with http/https.

What is the size limit?

Keep the main llms.txt file compact (typically under 100KB) for quick, lightweight crawler scans.
