How does usedby know which AI a company uses?

Each tool is linked to a public page that names the company: a vendor customer page, a published case study, a press release or a job post. We save most pages with a dated capture. Each line carries a proof level: confirmed (a case study, a named quote or a press release), observed (the vendor shows the company on its own pages) or signal (a job post shows employees use the tool). Every level counts as a tool the company uses; a signal is the weakest proof.
