Your chats leak.We keep the receipts.
Anthropic’s Claude chats, including a patient medical report and internal company files, were left exposed to Google via the “share” feature. Anthropic said the system was working as intended.
DeepSeek shared-chat links are being indexed by Google, making private conversations searchable. Researcher David Konitzny found the warning doesn’t mention search engine indexing.
Anthropic removed a hidden Claude Code tracker that flagged Chinese users via “prompt steganography” after a researcher exposed it. An engineer called it an “experiment.”
A researcher found Claude Code hides markers in the “Today’s date is…” system prompt line, encoding user timezone and API URL data via invisible Unicode tricks.
Anthropic became the third AI firm whose Claude chats appeared in Google search. Despite blocking crawlers, ~600 shared conversations were indexed before removal.
xAI published 370,000+ Grok chat transcripts to Google without users’ knowledge via its “share” button — some containing instructions for drugs, bombs, and a plot to kill Musk.
R2 Copilot encrypts what you write on your device and discards it when you close the add-in. Nothing to index, nothing to leak, nothing to archive later.
