Claude Chat Logs Surface in Search Results
Over the weekend, users of Anthropic's Claude chatbot learned that some of their conversations could be found via search engines like Google and Bing. The discovery has prompted questions about how much control users have over their shared online content.
Anthropic allows Claude users to create public links to chat threads, similar to sharing options on Google Docs. Anyone with the link can view the conversation, but users may not have realized that these linked chats can appear in public search results. As of Tuesday morning, no Claude chats appeared in Google or Bing searches that had previously surfaced them.
Reddit Sparks Awareness
The uproar began Sunday after Reddit users found that typing “site:claude.ai/share” into Google or Bing pulled up chat logs containing personal conversations. Once users create publicly shareable links, the chats become public and may be indexed by search engines. What was intended for a small group could inadvertently be shared with the entire internet.
This is not the first time. After a similar incident in September, Anthropic told Forbes that chats became visible on Google and Bing because they had been shared online or on social media. Anthropic said it uses a “robots.txt” file to prevent indexing, but both Google and Bing recommend adding a “noindex” HTML tag to block pages from search results. Many of the exposed chats lacked that tag, according to Wired. Anthropic did not respond to questions about whether it had added the tag to shared links and declined to comment, though it previously told other publications it does not share chat directories or sitemaps with search engines.
Similar Issue with Google Drive
The Guardian used a similar search query for Google Drive files with public links and found a long list of sensitive documents, including exams, lead and radon test results, and a city health department confidentiality agreement. Some files dated back to 2003. Google spokesperson Ross Richendrfer said these documents were discoverable because their links had been posted somewhere on the internet or social media.
Neither Google nor Anthropic warn users that their files might be indexed by search engines when creating shareable links. Jacob Hoffman-Andrews, a senior staff technologist at the Electronic Frontier Foundation, said “the privacy afforded by ‘anyone with a link’-style sharing of chats and documents is fragile. If you share something with a friend, and they share it with a friend, and they post it to social media, suddenly it’s findable and readable by anyone on the web.” He advised users to exercise “extreme caution” when creating shareable links and to consider alternatives like copying text or taking screenshots.
How to Protect Your Content
Users can unpublish previously shared chats or Google files. On Claude's desktop browser, click your profile icon, go to settings, then the privacy tab, and under “your data” click “manage” public chats to delete them. On Google Drive, open each public document, click the “share” button, and change “general access” from “anyone with the link” to “restricted” or specific people or groups.
Hoffman-Andrews warned: “Designing to incentivize viral sharing can also lead to users unintentionally oversharing.” The incident serves as a reminder to be cautious about what information is shared with “anyone with the link.”
