Claude shared chats and Artifacts may have ended up on Google

2 months ago

Claude chats and Artifacts became publicly searchable on Google after a Reddit user discovered that using search operators like 'site:claude.ai/share' revealed a long list of shared conversations.
Exposed data included sensitive information such as health records, private company documents, and the names and phone numbers of children.
Anthropic attributed the exposure to users publicly sharing links, stating that private links remain out of search results, and emphasized that they do not share chat directories with search engines.
The issue was first flagged on Reddit and reported by 404 Media and TechCrunch; by Monday afternoon, a test search showed no results, suggesting remediation.
Futurism reported finding medical reports, clinical trial results with patient names, children's personal data, internal company documents, and employee reviews with personal information.
Exposed Artifacts also included code and work notes, and one chat labeled 'shared by Anthropic' showed Claude producing erotica, violating usage policy.
Google stated that it does not control what pages are made public, and site owners have controls to prevent crawling or indexing.
A similar incident occurred last year when hundreds of Claude chats were indexed by search engines, and a researcher scraped around 100,000 publicly shared ChatGPT conversations.
Users can review and manage their publicly shared Claude chats via Settings -> Privacy -> Shared Chats.
