United States of America Superintelligence (USASI) is an independent, unofficial directory documenting U.S. AI organizations and U.S.-led open models, software, and research. It is not a U.S. government website. The project helps visitors understand what organizations build, find publicly available AI resources, and trace claims to their original sources. Its catalog includes companies, research labs, foundations, and other organizations, alongside model families and releases, software, datasets, and evaluation tools.

USASI offers searchable directories, subject hubs, state-based browsing, explainers, a glossary, news, and a comparison workspace showing catalog coverage. Visitors can explore topics such as local AI, agents, robotics, evaluation, and datasets, or use guides to learn terminology, find usable tools, understand organizations, and check claims. The site also provides information about its review process, methodology, corrections, and data reuse. Entries link claims to sources and note when evidence was reviewed; information without supporting evidence is marked unknown, while unverified candidates are excluded from the published catalog.
