An unspecified number of Claude chat logs and Artifacts were discovered publicly searchable on Google over the weekend after Reddit users used Google search operators to locate shared links. Claude’s share chat feature lets users create links that allow anyone with the URL to view a conversation or project, a capability the interface describes as intended for friends, colleagues, and small groups. Search results showed that links posted on forums or social media could be indexed, while private links sent directly to individuals did not appear in search results, according to Anthropic. Reddit users first flagged the issue on Saturday, and 404 Media reported the story on Monday morning; subsequent searches by TechCrunch on Monday afternoon returned no results, indicating that the exposure had been remedied. Futurism, Fortune, and other outlets reported finding health records, internal company documents, personal information of children, and erotica within exposed chats, illustrating the range of data that may have been accessible. Anthropic attributed the exposure to user actions, stating that share links are only discoverable when users post them publicly, and that the company does not provide chat directories or sitemaps to search engines, a position echoed by Google, which said it respects site owners’ crawling directives. Users can review and modify sharing settings in the Privacy section of Claude’s settings, where options to keep chats private or create public links are available.
