SeenSure, watched by SeenSure
Most software in this category asks you to trust a testimonial. We do not have any — the product is new and has no customers yet, and inventing some would sit badly with a tool whose whole job is refusing to overstate evidence.
So here is the other thing we can do: run it on ourselves, in public. Every row below is a real AI crawler that really reached this site, recorded by the same beacon a customer installs, and checked the same way.
0 of 2 crawlers proved who they were; 2 sent the name and could not be verified.
Why "claimed only" is on this page
A user-agent header is a claim. Anything can send a request saying it is GPTBot, and plenty of things do. So a row marked claimed only means requests arrived wearing that name and neither the signature nor the source address checked out — and we would rather show you that than quietly count it as a visit.
Address verified means the request came from inside the range that crawler's operator publishes. Signed is stronger still: the operator's own key signed the request. Both are proof; the difference is how much.
It would be easy to hide the unverified rows and make this table look cleaner. They are the most useful thing on it.
How this is measured
The same way it would be on your site. A few lines run on our server, before any HTML is rendered, and report each crawler visit — server-side because AI crawlers do not execute JavaScript, so a script tag would faithfully record every human visitor and not one crawler. Then the visitor's address is checked against the list its operator publishes, refreshed daily.
Full method, including where it cannot tell and says so, is on how it works.
