CrawlCheck
Free AI visibility audit · ChatGPT, Claude, Perplexity, Google

See what AI crawlers actually receive from your site — graded A–F, free.

Can ChatGPT, Claude, Perplexity and Google reach you, read you and safely quote you — and what to fix first.

CrawlCheck is a free AI visibility audit: it fetches your site the way AI crawlers do, grades what they get A–F and counts every defect by severity. We implement the fix list for $749.

No signup. Nothing installed. Nothing changed on your site.

  • Reach — can AI crawlers get your pages?
  • Read — do they get real words and files that parse?
  • Quote — is there a clear fact they can repeat about you?

Paying never changes a score.

Built and run by one person in Denver, on the client sites it measures — the demo report is a real, unretouched scan.

Who it is for

Three ways in.

Site owner

Tell me what is broken, and fix it.

Scan free. We implement the fix list for $749 and verify it with a re-scan; monitoring keeps it fixed from $29 a month.

Agency

Monitor clients and prove the work.

40 domains on one key, client-safe reports, change receipts a client can verify, and the API: 5,000 scans a month.

Agency plan →

Developer

Use the measurement in code.

Report JSON with the evidence behind every finding, batch scans, webhooks and a CI gate, from 2,000 scans a month.

API docs →

Trust

What it measures, and what it does not claim.

Method

Every rule and threshold is published.

What each check measures, what counts as passing, and the one limit: crawler identities are tested from our address, not an operator’s.

How it works →

Privacy

What a scan sends and keeps.

About 30 read-only requests. Reports are kept 90 days; any domain can opt out without an account.

Data policy →

Open core

The reader is open source.

The robots.txt reader is MIT-licensed and tested against production.

crawlcheck-core →

Limits

Evidence, not a citation claim.

A scan proves what your server sent. It never claims an answer engine cited you, and paying never changes a score.

Start with the free scan.

If the machine layer is already clean, you will know in a minute and pay nothing. No login, nothing changed on your site, and ad-hoc scans are never published by name.

CrawlCheck certificate for crawlcheck.io: certified machine-readable This site carries its own certificate. The seal is recomputed from the latest measurement, so it would show a lapse the day one happened.
