More from AAI Innovations
All listings by AAI InnovationsSearch United States federal regulations from the electronic Code of Federal Regulations (eCFR) directly in Claude. The collection covers about 8,300 CFR parts across all 50 titles, in English. Each part carries its agency and its place in the title, chapter and part hierarchy.
Claude can find a part by words in its title or by its eCFR identifier (for example us-cfr-title40-part98), check its versions, and search inside it for the passage that answers your question. Results come back as document details and matching excerpts, so Claude can cite the exact section it relies on. Full documents are never returned in one piece.
Useful for compliance teams, regulatory affairs, and anyone who needs a precise answer from US federal rules, including NHTSA vehicle safety standards and EPA emissions rules.
