usedby tracks which companies publicly use which AI and software tools. Every customer line links to its public source and carries a proof level, strongest first: - CONFIRMED: a case study, named testimonial, press release, or the company's own public account - DECLARED: the company told usedby, or lists the vendor as a sub-processor - OBSERVED: a vendor logo wall or customers page, a DNS record, or a config file in public code - SIGNAL: a job post, the weakest proof With this connector, Claude can: - List the companies that use a tool, such as Harvey, Cursor or Clay - Show the AI and software stack of a company - Compare two tools and the customers they share - Show what companies of your industry and size use for a given task - Shortlist tools for a task against exact requirements (integrations, data residency, DPA, pricing), with the evidence for each check - Track customers newly listed by vendors Read-only, no account and no API key needed. Counts describe companies tracked on usedby, not market share.
