How does usedby know which companies use a tool?
Each company is linked to a public page that names it: a vendor customer page, a published case study, a press release or a job post. We save each page 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 the company’s employees use the tool, the weakest proof). Every level counts as a customer, and each line shows its level.
How many AI tools does usedby track?
484 tracked tools. 468 of them are AI tools with public customers, across 7,551 companies on usedby. A tool without a public customer keeps its page and appears at the end of the ranking.
