Private Claude Conversations Have Been Indexed by Search Engines

Google and Bing indexed publicly shared Claude chat links, making the conversations searchable beyond their intended audience.

The exposed chats included medical details, personal data, corporate information, and explicit material; most were later removed.

Anthropic said shared links are public by design, while an SEO expert argued the issue points to robots.txt being used instead of noindex.

The incident highlights privacy and security risks when AI chat sharing settings and search engine crawling controls are not aligned.
