Spock (https://spock.chat) is an AI assistant. When a user asks it about a web page, it reads that page on their behalf: one request per page the user's question needs, not a crawl. Requests carry the User-Agent "SpockFetch/1.0 (+https://spock.chat)" and are signed with Web Bot Auth; the key directory is at /.well-known/http-message-signatures-directory. Spock obeys robots.txt for the product token SpockFetch (else *), honours Content-Signal ai-input=no, and stops when a site refuses automated readers. Contact: louis@spock.chat
