I tried Proton's AI Paper Trail tool — and I couldn't believe how much data chatbots know about me (www.techradar.com)

Proton has launched an AI tool called Paper Trail that analyzes users' ChatGPT or Claude chat histories, revealing the extensive amount of personal data they may have unintentionally shared. Built on Proton's privacy-focused LLM, Lumo, the tool emphasizes data protection by claiming to delete user information immediately. Users have reported unsettling revelations, such as detailed profiling regarding their financial situations and health—often exceeding what they explicitly disclosed. This highlights the alarming capability of AI chatbots to derive personal insights from seemingly benign interactions, raising concerns about privacy and data retention practices. The significance of this tool lies in its potential to educate users about the privacy implications of engaging with AI platforms. With chatbots increasingly becoming data-rich environments, the ease of profiling individuals can lead to the commodification of personal information without users' informed consent. The findings also point to a broader issue in the AI/ML community, where the quest for improving models often overshadows the necessity for stringent user data protection. Experts advocate for better privacy practices, emphasizing the need for users to treat all interactions with AI as potentially vulnerable to exposure, thereby fostering a more cautious approach to digital privacy as reliance on AI technologies grows.
