Source: Shutterstock* 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. Many of the materials 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 the "share" button in the top right corner, Claude notes that sharing will create a "public" link, which "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. Other materials were shared in the form of Claude Artifacts, a feature that allows users to save certain projects as standalone apps or tools. That platform *does* warn users that publishing an Artifact "will make it accessible to anyone on the internet and potentially visible in search engine results." Some of the materials 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 seems as though it was only intended to be shared internally at a company, or between a small handful of people. Such documents, 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]() by Redditors over the weekend. As of today, the chats remain searchable. This isn't the first time this has happened at Anthropic: [*Forbes* reported last year]() 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]() and [Grok chat logs]() were revealed to have discoverable in Google. Reached for comment, Anthropic said the system was working as intended. "We give people control over sharing their Claude conversations publicly, and in keeping with our privacy principles, we do not share chat directories or sitemaps with search engines like Google," the company said in a statement. "These shareable links are not guessable or discoverable unless people choose to share them themselves. 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." However, in its investigation last year, *Forbes* tracked down a user whose Claude material was appearing in Google search results who denied sharing the materials online. 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. **More on Anthropic:** [*Anthropic Caught Secretly Spying on Users*]() ## Author At Futurism, I've reported extensively on the rise of AI as a cultural and business force shaping the media industry, and more broadly how those dynamics are changing how we all consume and share information and relate to one another. I'm also fascinated by public health policy and ethics, the role of emerging tech in politics and governance — and the powerful people and forces at those intersections — climate change, and the environment. My investigation on Sports Illustrated's use of AI-generated authors with fictional biographies won a 2024 Mirror Award for "Best Story on Media Coverage of Artificial Intelligence in Journalism and the Media" from Syracuse University's SI Newhouse School, I contributed to Niemen Lab's 2025 Predictions for Journalism series, and I've discussed my work for Futurism during appearances on NPR, CNN, the BBC, the CBC, and more. I grew up in rural Pennsylvania and attended the University of Massachusetts Amherst, where I played Division I field hockey for the Minutewomen as a midfielder. Since then, I've lived in New Orleans, Louisiana and Manhattan, New York. I spend my free time running, reading, perusing archival fashion, and searching for the world’s best negroni. I also have a debonair tuxedo cat, Westley, who's named after "The Princess Bride." ### Author social links [Bluesky]()
