## AI tools

Each line links to the public page that shows the company with the tool. Every line is a customer, at one of three proof levels: 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 the company's employees use the tool, the weakest proof). The first public proof is not an adoption date.
