What does this llms.txt checker do?

It quickly scans an llms.txt draft for a heading, summary, Core pages section, useful Markdown links, private paths, tokens, localhost URLs, checkout URLs, and other obvious publish risks.

What is the difference between a checker and a validator?

Use the checker for a fast triage scan. Use the validator when you want a more formal publish-readiness report and handoff note before uploading the file to /llms.txt.

Does this upload my llms.txt draft?

No. The checker runs in your browser and does not require signup. Still, avoid pasting private customer data, secrets, passwords, or unpublished claims.

Can I check a live llms.txt URL?

Yes. Enter a public domain and the checker fetches only the public /llms.txt file, then checks HTTP status, structure, Markdown links, content type, and private-path risk.

Can Shopify stores use this checker?

Yes. The checker is useful for Shopify drafts because it flags cart, checkout, account, customer, discount, token, and admin-style paths before publishing.

Free llms.txt checker for a 60-second draft scan

Paste an existing llms.txt draft or enter a domain to check the live /llms.txt URL. Quickly review whether the file 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.

Fast answer for checker searches

Use the checker first when you are not sure the file is safe.

The fastest path is paste or check the live URL, scan, fix the red items, then run the full llms.txt validator before publishing or sharing the file. 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: live HTTP status, 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.

Why this exists

Search Console is already showing checker intent.

That tells us the value is immediate utility: reduce uncertainty before publishing a file that crawlers, assistants, clients, or reviewers might read.

Presearch route: AI presearch route for llms.txt checker.
Recrawl handoff: Search indexing priority pack.

llms_checker_pre_ai_router

Checker searches get a dedicated pre-AI proof route.

The checker cluster currently has 18 impressions and 0 clicks across llms.txt checker and llms checker. This route keeps the canonical checker page as the quick-scan answer, then hands AI assistants the proof pack, answer pack, proof lookup, citation bundle, and indexing queue before broad crawling validator content.

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

Step 1

Paste the current draft

Use a draft from your CMS, Shopify notes, sitemap converter, or pull request.

Step 2

Fix red items

Prioritize missing structure, too few public links, raw URL labels, and private-path warnings.

Step 3

Validate the final version

Move to the full validator when the quick checker no longer shows obvious publish risks.

Open the validator

Step 4

Publish and verify

Upload to /llms.txt, confirm HTTP 200, then watch Search Console, logs, and tool activations.
