Fast answer for checker searches
Why this exists
Free llms.txt Checker for a 60-second draft scan.
Paste an existing llms.txt draft and quickly check whether it has the basics: one clear heading, a useful summary, Core pages, Optional links, public canonical URLs, and no obvious private paths. This page is built for searches like llms.txt checker, llms checker, and check llms.txt file.
Use the checker first when you are not sure the file is safe.
The fastest path is paste, scan, fix the red items, then run the full llms.txt validator before publishing at /llms.txt. The checker is intentionally conservative: it would rather warn you about account, checkout, token, staging, or admin URLs than let a risky file go live.
- Best fit: quick review before a pull request, client handoff, Shopify upload, or root-file publish.
- Checks: H1, summary, Important notes, Core pages, Optional section, Markdown links, link labels, valid URLs, and private-path patterns.
- Does not promise: rankings, citations, crawl priority, or AI traffic. It only helps make the public file clearer and safer.
Search Console is already showing checker intent.
People are not only searching for a broad llms.txt guide. They are searching for a practical checker. That tells us the value is immediate utility: reduce uncertainty before publishing a file that crawlers, assistants, clients, or reviewers might read.

Recommendations
Remove private paths first
Before worrying about wording, remove admin, account, checkout, customer, token, localhost, staging, and private URLs.
Keep the public map short
A useful llms.txt file is closer to a concise public context map than a full sitemap dump.
Checker workflow before publishing
Paste the current draft
Use a draft from your CMS, Shopify notes, sitemap converter, or pull request.
Fix red items
Prioritize missing structure, too few public links, raw URL labels, and private-path warnings.
Validate the final version
Move to the full validator when the quick checker no longer shows obvious publish risks.
Open the validatorPublish and verify
Upload to /llms.txt, confirm HTTP 200, then watch Search Console, logs, and tool activations.
Checker vs validator vs generator
Pick the page that matches the job. This reduces pogo-sticking and makes internal links more useful for searchers and AI assistants.
