A Whole Bunch of People’s Claude Chats Are Publicly Accessible Online, and There’s Some Wildly Private Stuff in There

A trove of chat logs and projects created with Anthropic's Claude, including sensitive personal and company information, have been left exposed to Google and are searchable to anyone on the web. The artifacts were made public when Claude users used the chatbot's "share" feature, which creates a public link but does not warn users that shared content could be indexed by search engines. Anthropic has not responded to a request for comment, and as of this morning the chats remain searchable.

A trove of chat logs and projects created with Anthropic’s Claude — some including sensitive personal and company information — have been left exposed to Google, making them them searchable to anyone on the web. The artifacts appear to have been made public when Claude users opted to distribute a given chat or project to colleagues or associates using the chatbot’s “share” feature. After hitting a “share” button in the top right corner, Claude notes that sharing will create a “public” link, and “anyone with the link can view.” The warning, though, doesn’t alert users that shared content could wind up being indexed by a search engine — meaning that a user could effectively be sharing their Claude-generated document with the entire internet. Some of the artifacts exposed to the web and indexed by Google, such as personal websites and some vibe-coded apps, appear to have been created for public consumption. But much of the discoverable content was likely intended to be shared internally at a company, or between a small handful of people. Such artifacts, which were reviewed by Futurism by way of Google Search, included what appeared to be a detailed medical report of a real patient, clinical trial results that included patient names, documents sharing the names and phone numbers of primary school-aged children, company documents marked for internal use only, and employee reviews that included personal information about workers. We’re opting not to share any links to the content out of concern for users’ privacy. The exposure was first spotted https://www.reddit.com/r/ClaudeAI/comments/1v6fiyj/you can view a lot of shared conversations via/ by Redditors. Reached late Sunday evening, Anthropic hasn’t responded to a request for comment. As of this morning, the chats remain searchable. This isn’t the first time this has happened at Anthropic: Forbes reported last year https://www.forbes.com/sites/iainmartin/2025/09/08/hundreds-of-anthropic-chatbot-transcripts-showed-up-in-google-search/ that hundreds of Claude chats had been indexed by search engines, prompting Anthropic to scrub the chats from the web. OpenAI and xAI have each been similarly caught in hot water after ChatGPT https://www.fastcompany.com/91376687/google-indexing-chatgpt-conversations and Grok chat logs https://www.bbc.com/news/articles/cdrkmk00jy0o were revealed to have discoverable in Google. If you’re hoping to send Claude-generated documents that may include sensitive information to colleagues, friends, or loved ones: you might want to stop hitting the “share” button, and instead opt to copy-paste the Claude-generated text into a secure document.
