llms.txt Validator
Check an existing /llms.txt file or validate pasted Markdown before publishing. The workbench keeps the validation result and fixed version beside the input.
A clean llms.txt can help clarify public website context, but it is not a guarantee of AI rankings, citations, or crawler behavior.
Validator
Check llms.txt quality
Validate on the left; keep results, issues, and the fixed version preview beside the input.
Validation result
Not checked
Choose URL mode or Text mode, then run validation to see structure, placeholder, and recommendation details. Fixed-version copy is disabled until a result exists.
Structure
Validate H1 title, summary blockquote, sections, content length, and useful public links.
Placeholder risk
Catch lorem ipsum, TODO, coming soon, sample description, and other placeholder phrases before they leak to production.
Public URL safety
URL mode only checks public websites. Do not submit private dashboards, intranet URLs, signed links, secrets, or customer data.
FAQ
What does the llms.txt Validator check?
It checks whether llms.txt exists, has useful Markdown structure, includes an H1, summary blockquote, sections, links, and avoids obvious placeholder copy.
Does a valid llms.txt guarantee AI discovery?
No. llms.txt is an optional proposed signal and does not guarantee AI rankings, citations, crawler behavior, or assistant recommendations.
Can I paste text instead of fetching a URL?
Yes. Use Text mode to validate draft content before publishing. URL mode fetches /llms.txt from a public website and rejects private or localhost URLs.

After validation, revisit crawler access or update policy if needed.
Keep navigation in one predictable place: check crawler access, generate policy, create llms.txt context, then validate before publishing.
