Proton’s Tool Reveals What ChatGPT and Claude Know
Swiss provider Proton launched AI Paper Trail, a browser tool that analyzes exported chat data (zip/json) from ChatGPT and Anthropic’s Claude to summarize what those chatbots may have learned about a user. The tool — which currently supports ChatGPT and Claude exports — reports metrics such as a “Privacy Exposure” score and an estimated monetary value of a user’s data. A Bitkom survey of 1,003 Germans found 34% of AI users consult chatbots for health questions and 43% of respondents worry personal data are not securely stored by AI providers. The article notes OpenAI and Anthropic say they do not build advertising profiles from user data but may use exports for model training depending on settings; deleted chats can still be retained in some cases (Anthropic: at least 30 days). Proton positions the tool to highlight privacy exposure and to promote its privacy-focused Lumo chatbot; its transparency report shows past compliance with Swiss authority orders for Proton Mail.
