Is Claude-User blocked on your site?
Claude-User is the Claude (live browsing) crawler that fetches a page live when a user asks about it. If your robots.txt blocks it, that engine cannot read your pages, and a page it cannot read is a page it can never cite.
Free, no sign-up. We fetch one public file and read it. Nothing is stored.
