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.)
