Shared Claude chats were searchable on Google

July 28, 2026 · Malwarebytes · Severity: MEDIUM

Reddit users discovered that shared conversations from Anthropic's Claude AI chatbot were appearing in Google search results, exposing sensitive data like crypto wallet keys, personal details, and private discussions. The issue stemmed from Claude's Share feature, which generated public web links for shared chats and Artifacts (interactive documents created by Claude). While Anthropic has reportedly fixed the Google indexing problem, shared links remain accessible to those who already have them, and Wired confirmed Bing still surfaces these results. This incident highlights the broader risk of users unknowingly making AI chats public when using share features, similar to past exposures involving Grok and Meta AI. The exposure underscores how easily shared AI conversations can become publicly discoverable, especially when indexed by search engines. Although Claude chats are private by default, users who explicitly shared conversations inadvertently made them accessible beyond intended recipients. To mitigate risks, experts advise avoiding sharing personally identifiable information with chatbots and reviewing privacy settings. The incident serves as a reminder that AI chat sharing functions more like publishing than private messaging, with limited user control over indexing. Users should assume shared content could become public and utilize temporary chat options when available, though these don’t guarantee complete privacy.

Reddit users found that by using a specific Google search query, it was possible to find Claude conversations that users had shared.

This exposed sensitive material, including crypto wallet keys, names, addresses, work notes, and even erotic or otherwise policy-violating chats. Fortune says Anthropic appears to have fixed the Google indexing issue, but the shared links themselves were still live for people who already had them.

The exposure was tied to Claude’s Share feature, which creates a public web link to a snapshot of a conversation rather than leaving it inside a user’s private account. Reddit users found a search query that surfaced many of these shared chats, plus Claude Artifacts (interactive documents, apps, and other content created by Claude) in Google results. Wired reports that this is still true for Bing.

The main risk is that people use chatbots to think through work, health, legal, or personal matters without realizing that a shared link can behave like ordinary public web content.

This isn’t unique to Claude. We’ve previously seen Grok chats show up in Google search results, and Meta AI conversations can also become public by design. We have also written about the share option in ChatGPT that was swiftly removed after users unintentionally made thousands of conversations searchable.

Anthropic says Claude chats are private by default, and only conversations users explicitly chose to share were affected. But the incident is a reminder that a “share” button on an AI chat can be more like publishing than messaging, especially if search engines can discover the resulting URL.

How to stay safe

The easy way out here is not to share your AI chatbot conversations with anyone, because you could end up reaching more people than you intended.

That’s because it’s harder to stop pages from being indexed than you might expect. And you don’t have those controls aren’t in your hands. The AI provider should take care of that.

But there are a few things you can do:

Don’t share Personally Identifiable Information (PII) with a chatbot, so that if a conversation is ever exposed it can’t be easily linked back to you.
To review or stop sharing conversations in Claude, go to Settings > Privacy > Shared chats.
If you’re using an AI service from a social media company, such as Meta AI, Grok, or Gemini), remember that your conversations could be tied to your account—which might contain a lot of personal information.
When using AI, make sure you understand how to keep your conversations private. Many services offer temporary or incognito chats that aren’t saved to your history, but they aren’t a guarantee against bugs, leaks, or data breaches. Only use the share feature when you’re comfortable with anyone potentially seeing that conversation.
Read the privacy policy so you understand how your conversations are stored and shared. If it’s too long, you can always ask an AI to summarise the important points.

Let’s face it, an incognito window can only do so much.
