Private Claude Chats Were Posted Publicly on Google (And It's Not The First Time)

An untold number of shared Claude conversations and Artifacts, the mini-apps and documents users build inside Claude, were found publicly searchable on Google over the weekend, according to TechCrunch and 404 Media. Some reportedly contained medical records, internal company documents, and the names and phone numbers of children.^[1][2]

The exposure was not unique to Claude. Shared ChatGPT conversations have surfaced in Google results before, and the common thread is a feature most major AI tools now offer: a link that lets users share a chat. For anyone who uses that option, the practical question is whether Claude and similar tools are safe to share conversations on, and how those links can become publicly searchable.

How Claude shared chats ended up in Google search results

The issue surfaced when Reddit users found that a search operator like site:claude.ai/share returned a list of shared conversations in Google. A Reddit user first flagged it on Saturday, and 404 Media first reported it on Monday.

The exposed chats contained sensitive information. Futurism reported finding a detailed medical report of a real patient, clinical trial results that included patient names, documents listing the names and phone numbers of primary school-aged children, company files marked for internal use only, and employee reviews containing personal information about workers. Exposed Artifacts included code and work notes.

The exposure did not stem from a breach of Anthropic's systems. It traces to Claude's share feature, which lets users create a link so anyone who has it can view a conversation. According to VentureBeat, Anthropic's system asked search engines not to crawl the share directory, but the pages lacked a “noindex” instruction, so once a public link was posted somewhere crawlable, Google could index the conversation.

Anthropic disputed the framing that it exposed user data. “These shareable links are not guessable or discoverable unless people choose to share them themselves,” spokeswoman Amie Rotherham said. “When someone shares a conversation, they are making that content publicly accessible, and like other public web content, it may be archived by third-party services.” As of Monday afternoon, a test search by TechCrunch no longer returned results, which the outlet said suggested the exposure had been remediated.

What the Claude leak means for anyone who shares AI chats

Claude's share feature creates a link that, in the company's words, lets “anyone with the link” view a conversation. That differs from a comparable Google Docs link, which does not appear in Google search results. An indexed Claude share page, by contrast, could be surfaced through a search query.

Deleting a chat may also not fully undo the exposure. Once a page has been indexed or archived, it can persist elsewhere, which is why Anthropic's statement noted that shared content “may be archived by third-party services.” 

The problem has precedent, and it is not limited to Anthropic. In September 2025, Forbes reported that Google had indexed just under 600 Claude conversations before they were removed. 404 Media previously found that roughly 100,000 shared ChatGPT conversations were searchable on Google.

How to check whether your AI chats are private

Several steps can reduce the risk that a shared conversation becomes public.

1. Audit your shared Claude chats. In Claude, go to Settings > Privacy > Shared Chats to review conversations you have made public, and revoke links you no longer need.
2. Do the same across other AI tools. ChatGPT, Gemini, Meta AI, and others also offer sharing. Check each one's settings and remove old public links. 
3. Limit sensitive data in shareable chats. Medical details, financial information, government IDs, and other people's personal information carry the most risk if a conversation becomes public.
4. Request removal of an exposed page. If a shared chat was indexed, you can request removal of your personal information from Google.
5. Check for existing exposure. A free data exposure scan can show what information is already public, and data broker removal can help remove some of it.

Bottom line: Is Claude safe, and are your AI chats private?

This specific exposure appears to have been remediated, and it stemmed from shared links rather than a breach of Anthropic's systems. But any AI conversation shared through a link can potentially be indexed by a search engine or archived by a third party, and that applies across AI chatbots, not only Claude. To limit exposure, review the share links in each AI tool you use, revoke the ones you no longer need, and keep sensitive information out of conversations you might share.
