How does usedby know which AI tools Yahoo uses?
Each tool is linked to a public page that names Yahoo: a vendor's customer page, a published case study, a press release or a job post. We save each page with a dated capture and check it again on each run. A tool leaves the list only after three checks in a row that no longer find Yahoo, and at least 14 days after it was last seen. A tool with a published case study or quote is never removed automatically.
