Publicly Shared Claude Artifacts Reportedly Became Discoverable Through Google Search

Users reported that publicly shared Claude Artifacts (apps, documents, spreadsheets, and other files) could be found through Google Search. Reportedly, indexed artifacts containing business plans, infrastructure diagrams, clinical-trial planning materials, and other potentially sensitive content were also located. Anthropic said links became searchable only after being posted somewhere crawlable.
