A Markdown report and CSV row you can paste into launch notes, crawler-lag reviews, or directory approval tracking.
The comparison uses text already pasted into the page. No remote fetch is required, which avoids CORS, rate-limit, and private-site surprises.
Browser-only comparison
The original `llms.txt` proposal describes a Markdown file at the site root that points language models toward useful content. Treat it as a readable map, not a crawler-control guarantee.
Open llmstxt.orgLLMS Central documents public read endpoints for search, domain `llms.txt` retrieval, and direct `/{domain}/llms.txt` access. This checker gives you a no-account way to compare those copies manually.
