WhatsApp Adds Meta AI Chats That Are Built to Be Fully Private

WhatsApp announced "Incognito Chat," an AI chat feature that integrates Meta AI while aiming to prevent Meta from accessing users' questions and answers by running inference inside a Trusted Execution Environment as part of its Private Processing system; conversations are ephemeral by default and the company plans third-party audits and oversight. The piece focuses on privacy design, limitations (text-only initially), and the balance between on-device privacy and server-side compute, and does not describe a security incident.
