llms.txt checker

Validate any site's llms.txt against the llmstxt.org format: title, summary, sections, link format — and whether the linked pages actually load.

What the checker looks at

  • Title — the file starts with one # Site name line.
  • Summary — a short > blockquote right after the title.
  • Sections and links — ## Section headings with - [Title](url): description lists.
  • Linked pages — the first links are fetched to make sure they load; Markdown (.md) targets are preferred.
  • Extras — content type, size, an Optional section and llms-full.txt.
