What you are and are not buying
Will this get my site cited by ChatGPT or Perplexity? We do not know, and neither does anyone selling that. llms.txt is a proposal some assistants read and others ignore. Monitor tells you whether the file is correct and whether a named user-agent fetched it. That is the entire claim.
What does the canary prove? That something requesting with a given User-Agent string followed a link that exists only in your llms.txt. User-Agent strings are self-declared and can be faked, so a match is evidence, not identity. No hits means no hits on that link; it says nothing about whether the file was read another way.
What happens when I cancel? Checks stop at the end of the paid period. Your domains, runs and fetch log stay readable for 90 days, then they are deleted. Failed payments get a 7-day grace period with an email before anything pauses.
Can I monitor a domain I do not own? No. Monitoring needs a DNS TXT record or a meta tag on the home page. The free tools have no such check because they change nothing on your site.
