As artificial intelligence tools like ChatGPT, Gemini, Claude, Microsoft Copilot, and Grok become integrated into daily life, users are being advised to exercise caution regarding data privacy. Experts suggest treating chatbots with the same caution as a stranger and avoiding the input of any information that a user would not be comfortable sharing publicly. Further analysis highlights that users often share more information than necessary because they do not perceive chatbots as corporate entities, leading to a loss of control over how submitted data is stored or utilized. Security concerns are underscored by past technical errors, such as a 2023 OpenAI incident that allowed users to view others' personal information. Experts specifically advise against sharing personally identifiable information, including ID numbers, passports, home addresses, or full dates of birth.

Broader scrutiny has emerged regarding data sovereignty and enterprise security. A report by DeutschlandGPT comparing twelve AI platforms found that being a European provider does not guarantee data sovereignty, noting that some European companies failed to meet the criterion of “data processing within the EU”. ~~Additionally, security experts are warning of increased hacking attempts targeting AI accounts as users input more confidential business details.~~
