WhatsApp Introduces Private AI Chats
WhatsApp has launched a new AI feature called Incognito Chat. This allows users to chat privately with Meta AI. Importantly, Meta cannot see the questions or answers. The feature is built on WhatsApp’s Private Processing system, which started a year ago. This system already supports message summaries and writing tools. Incognito Chat aims to give users a way to use AI without risking privacy. The conversations are private, and Meta only knows that the feature was used, not what was said.
How Incognito Chat Keeps Conversations Private
Incognito Chat is designed to protect user privacy fully. These chats are temporary and disappear after the session ends. The system runs the AI inference in a Trusted Execution Environment. This setup keeps messages hidden from anyone else, including Meta. Additionally, Meta invites third-party checks to verify the security of the system. However, users still need to trust Meta, as chats are processed in the cloud. Future plans include possibly saving some conversations for users who want to keep a chat history.
Functionality and Future Benefits
Right now, Incognito Chat works with text only, but support for images and voice is coming soon. To make the feature easy to use, Meta is working on reducing delays caused by processing AI securely. Besides Incognito Chat, Meta adds Side Chat with Meta AI. This feature lets users ask AI questions during a conversation with friends. For example, users can get restaurant tips or movie suggestions without sharing private interests with other companies. Overall, these updates aim to balance privacy and the convenience of AI.
