Anthropic's Claude chats briefly exposed on Google, raising privacy alarms

Key Points

• Reddit users discovered Claude chats searchable on Google via "site:claude.ai/share" query.
• Exposed content included medical records, internal company documents, and children's personal details.
• Anthropic attributes the leak to users sharing public links; company says it does not expose chat directories to search engines.
• Amie Rotherham emphasized that shareable links are only discoverable if users post them publicly.
• Google spokesperson Ned Adriance noted that search engines index only pages that are publicly accessible.
• By Monday afternoon, a test search showed no results, suggesting the issue was remedied.
• Previous incidents last year saw hundreds of Claude chats indexed before disappearing.
• Anthropic advises users to review shared links in Settings → Privacy → Shared Chats.
