If you’ve ever shared a Claude conversation using a public link, it might be worth checking your privacy settings. Over the weekend, users discovered that publicly shared Claude chats and Artifacts were appearing in Google Search and other search engines through queries such as site:claude.ai/share. The indexed pages reportedly included everything from resumes and business documents to API keys, health information, and other sensitive conversations that users likely never expected to become searchable.
How did this happen?
Importantly, this wasn’t the result of a hack or data breach. Instead, the conversations were shared using Claude’s built-in Share feature.
Claude allows users to generate a public share link, creating a snapshot of a conversation that anyone with the URL can access. That snapshot also includes any Artifacts such as interactive documents, apps, or code generated during the conversation. While the feature is intended for collaboration, users discovered that some of these public pages had also been indexed by search engines, making them discoverable through simple Google searches.
The issue first gained traction after Reddit users noticed hundreds of searchable Claude conversations over the weekend. Reports suggest that many users assumed “anyone with the link” meant the content wouldn’t appear in search results unless someone explicitly shared the URL with them, leading to understandable confusion once Google indexing came to light.
What Anthropic and Google are saying
Anthropic says the behavior wasn’t the result of a bug or data breach, but rather how its sharing feature is designed to work. The company told TechCrunch that Claude chats remain private by default, and it doesn’t publish chat directories or sitemaps for search engines. However, if a user shares a public Claude link on a website, forum, or social platform that can be crawled, search engines may index it like any other publicly accessible webpage.
The company’s Privacy Center also states that shared chats create a public snapshot of the conversation, including any Artifacts generated before the link was created. Users can revoke access at any time by heading to Settings > Privacy > Shared Chats and unsharing the conversation. That said, previously indexed pages may continue to appear in search results or cached archives until they’re refreshed.
Google, meanwhile, says the responsibility lies with the website hosting the content. In a statement to TechCrunch, spokesperson Ned Adriance said search engines don’t decide which pages are made public, noting that Google provides website owners with controls to prevent crawling or indexing and respects those directives. The incident serves as a timely reminder that once content is made publicly accessible on the web, it can often be treated like any other webpage — even if it started as a private AI conversation.
