About
A check you can run without handing over an email.
Most tools that look for copies of a website ask you to sign up before they show you anything, or show you a few results and keep the rest behind a plan. That is backwards for someone who just wants to know whether there is a problem. So this check is free, needs no account, and shows everything it finds.
What it does
It reads up to ten of your pages, sets aside the parts every site shares (menus, footers, cookie notices), and picks the sentences and photos that are most clearly yours. It searches for each of them, then opens every page that came back to confirm your words are really there and to count how many of them it carries, in your order.
For the bigger matches it also looks at public dates: when the Internet Archive first saw each page, what each page says about its own publish date, and when the other domain was registered. And it looks for a link back to you, because a page that credits you is a different conversation.
What it is careful not to say
A match is never called a theft here. Text gets reused with permission all the time: suppliers hand out product descriptions, speakers send out the same bio, agencies reuse their own templates. The check tells you where to look and how much overlaps. Deciding what it means is up to you, after you have read the page.
It also does not see everything. It depends on what search engines show, and it only matches the same words in the same order or the same photo file. If it finds nothing, that is good news, not proof.
Who runs it
A small team that works on copyright notices for website owners. If you leave your email under your results, one of us reads them and replies. We do not pass your results to anyone, and we do not add you to a mailing list.
